Cocobolo (Dalbergia retusa)
Cocobolo (Dalbergia retusa)

Common Name(s): Cocobolo (many variant spellings, such as cocabola or cocobola)

Scientific Name: Dalbergia retusa

Distribution: Central America

Tree Size: 45-60 ft (14-18 m) tall,

                     1.5-2 ft (50-60 cm) trunk diameter

Average Dried Weight: 68.5 lbs/ft3 (1,095 kg/m3)

Specific Gravity (Basic, 12% MC): 0.89, 1.1

Janka Hardness: 2,960 lbf (14,140 N)

Modulus of Rupture: 22,910 lbf/in2 (158 MPa)*

Elastic Modulus: 2,712,000 lbf/in2 (18.7 GPa)*

Crushing Strength: 11,790 lbf/in2 (81.3 MPa)*

*values from tentative strength group assessment per South American Timbers

Shrinkage: Radial: 2.7%, Tangential: 4.3%,

                          Volumetric: 7%, T/R Ratio: 1.6

Color/Appearance: Cocobolo can be seen in a kaleidoscope of different colors, ranging from yellow, orange, red, and shades of brown with streaks of black or purple. Sapwood is typically a very pale yellow. Colors are lighter when freshly sanded/cut, and darken with age; for more information, see the article on preventing color changes in exotic woods.

Grain/Texture: Grain is straight to interlocked, with a fine, even texture. Good natural luster.

Rot Resistance: Rated as very durable, and also resistant to insect attack. Its natural oils are reported to give it good resistance to degrade from wet/dry cycles.

Workability: Due to the high oil content found in this wood, it can occasionally cause problems with gluing. Also, the wood’s color can bleed into surrounding wood when applying a finish, so care must be taken on the initial seal coats not to smear the wood’s color/oils into surrounding areas. Tearout can occur during planing if interlocked grain is present; the wood also has a moderate blunting effect on cutting edges/tools due to its high density. Cocobolo has excellent turning properties.

Odor: Cocobolo has a distinct spice-like scent when being worked, which some find unpleasant: though it has been used in at least one women’s perfume.

Allergies/Toxicity: Notoriously allergenic. Reported as a sensitizer; can cause skin, eye, and respiratory irritation, as well as nausea, pink-eye, and asthma-like symptoms. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Cocobolo is in limited supply, and is also in relatively high demand, (for ornamental purposes), and is likely to be quite expensive. Prices should compare similarly to other rosewoods in the Dalbergia genus.

Sustainability: Cocobolo is listed on CITES appendix II under the genus-wide restriction on all Dalbergia species—which also includes finished products made of the wood (though finished items under 10 kilograms are exempted). It is also listed on the IUCN Red List as vulnerable due to a population reduction of over 20% in the past three generations, caused by a decline in its natural range, and exploitation.

Common Uses: Fine furniture, musical instruments, turnings, and other small specialty objects.

Comments: One of today’s most prized lumbers for its outstanding color and figure—yet also one of the most infamous for its difficulty in gluing, and its tendency to cause allergic reactions in woodworkers.

Images: Drag the slider up/down to toggle between raw and finished wood. Because there is so much variation in the color and grain in cocobolo, three different samples are shown.

A special thanks to Steve Earis for providing the turned photos of this wood species.

Porosity: diffuse porous

Arrangement: solitary and radial multiples

Vessels: medium to very large, few to very few; reddish brown deposits common

Parenchyma: diffuse-in-aggregates, vasicentric, and banded (marginal)

Rays: narrow; normal to close spacing

Lookalikes/Substitutes: Can bear a similarity to many different genuine rosewood species. pau ferro (Machaerium spp.) has a very similar overall appearance that can also be confused with (or substituted for) cocobolo. In the latter’s case, cocobolo can be separated from lookalikes based on it’s large and very infrequent pores, averaging only about 3-6 pores per mm2.

Notes: Ripple marks present.

A box in cocobolo


Cocobolo baton.

steven smith

does this wood steam bend well or not please steven.

Serena Breeze

I have a Backun clarinet made from cocobolo wood. It is an amazing clarinet, the wood helps the sound resonate a lot more. Its a beautiful color and I recommend cocobolo wood for a solo clarinet or a wind symphony clarinet.

Jim LaForge

I have a cocobola baton from my dad when he was a cop in the 70’s.
I recently started using it I’m my martial arts practice and had to sand the finish off, ( as it was to slick).
Should I leave it natural or apply an oil?

Why is some cocobolo just purple and others have the yellow, red, brown, purple, black, ECT.
Thank you,


I’m currently in the process of having a pool cue made with Cocobolo. One of my other custom cues was made with ebony going into purple heart. It hits great. So, like getting tattoos, I had to get another. I’m having cocobolo going into purple heart. I don’t want to readjust my game by changing the purple heart. And since cocobolo is very similar in structure to ebony, I figure it should work. After paying for it in full upfront, I can’t wait to see it completed….let alone to use it. If anyone has images of their own cocobolo custom… Read more »

is this referred as Genuine Rosewood? My friend has these Rosewood from Brazil they were cut maybe 20 years ago and brought to Canada.

Carol Fairbrother

I have a wall clock made out of cocobolo wood. Two layers of shellac was applied but what kind of finish can be used now to complete the project and give it a more glossy look? Would appreciate any advice.


I was given a piece of wood that I cannot quite identify. From all the woods I know, it resembles Cocobolo the closest. It is very heavy and dense. The grain resembles cocobolo, but has some very tight grain in places. Only thing is it has a very purple color to it, not brown as pictured above. Also, when it is cut, it is very aromatic. A nice perfume smell with a hint of cinnamon. Can anyone help me identify it as cocobolo or something else? Thanks.


In Dalbergia, East Indian Rosewood and Kingwood are the most purple. I can’t remember the smell of Kingwood.

john watt

Have just used some kingwood to make some pens when drilling out the barrels the smell had a hint of single malt whisky to it


That green is also reported to sometimes GLOW softly.


I work as laser cutter operator (and other jobs) at Martin Guitar. While fairly uncommon, a very small handful of East Indian Rosewood guitar backs come through on an irregular basis with a green in the lighter portions of the heart wood. An oldtimer there told me that it almost shimmers and is often turns to a somewhat lustrous silver when finished to full gloss with lacquer. Similar case with EIR that has a red color in it, often in a thin streak. On another note, freshly sanded, cut, or steam bent cocobolo does have a very strong smell. Most… Read more »


I think the East Indian Rosewood that I have seen with yellows, oranges and green is plantation grown in Indonesia, called Sonokelling. The purples and reds seem to come from India.


It could be oxygenation or a UV reactivion. Obviously, things can respond to oxygenation so that may be the culprit. Maybe freshly cut the wood and seal it as quickly as possible? Also, there could be a UV reaction going on. UV rays can fade colors or even sometimes brighten them. Brazilian Rosewood, especially when submerged under water or exposed to minerals in the soil, can develop bands of green and red that are reactive in sunlight. Check out this image:

Hi, my late father who was a true craftsman when it came to working with wood was given a gift of some Cocobolo by a friend several years ago. He used it to add decoration to Grandfather Clock cases that he made but he also made a large ‘coffee table’ with a gloss sealant over the top and turned legs. It is a really beautiful and unique piece. As we live in Ireland it was quite unusual that he had this beautiful wood to work with. Unfortunately my home is not big enough to store all the work that my… Read more »

List The Lies

While I can’t comment on the quality of your father’s work, Cocobolo is a very expensive wood. Around $30 USD a board foot is typical (To give you some perspective, I can buy American Beech at my local hardwood supplier for 2.95 a bf). So if you have an entire coffee table made out of Cocobolo, then the table is probably worth a few hundred dollars in wood alone. Obviously that value can be lost if the craftsmanship/design is poor. As far as the finish quality/condition, I can’t really tell you how that would effect the value of a piece… Read more »


Wow!! That is very interesting Hoover!!! Please do share how testing and actual practices goes!

I am working on a project to make cocobolo wood into fine powder for the pharmaceutical industry.
there is a compound (toxic to fish and human skin) in cocobolo called OBTUSAQUINONE seems like is an alternative natural medice for poor people with cancer


Has anything new come to light since the 2013 mouse study?


i have recently been turning several items in cocobolo and have had a massive reaction to this wood it has total stripped the skin from my face and numbed most of my facial nerves it also penetrated my arms etc be very careful with this wood even though I was using face masks etc. it was not sufficient protection, this condition has lasted for two/three months and has taken a hell of a lot of clearing up, so once again please be very careful. All the best.


This applies to all true rosewoods (Dalbergia genus). Wear a mask and safety glasses when working. Shower after working with it for a few hours, as you generally should avoid sleeves in the woodshop, especially when turning. Disposable sleeves do exist and are used by some of my coworkers when working with rosewoods.

I recently purchased a beautiful bowl of Cocobolo. The grain and color is the most beautiful I have ever seen.
However: I have been warned that it will blacken over time and this really bothers me. A friend showed me a bowl he turned 15 years ago and it is so black you can hardly see the grain pattern.
Is there a finish that I can apply that will preserve the color and luster?


Not that I’maware of. The best thing I’ve found is to polish it out with micromesh, up to 12000. It’s some work, but the end result is astonishing. It looks like stone almost, but feels something like thesurface of an ipad. It will also make the wood look a bit lighter. you may not have a true cocobolo, but perhaps another very similar rosewood, which may notturn black brwn.


Dear Eric I have made a stain! This could be a really big seller! How much would you pay for natural wood-oil stain? Did I mention its water resistant? The color is bright orange-yellow and it smells great!


It takes just around 80 years for a Cocobolo tree to mature to harvest-able size.


We have a few dozen hectares of Honduran rosewood planted around 25 years ago in Guatemala. While not full size, it’s large enough to harvest. Our cocobolo is younger but I don’t think it’s a significantly slower grower than Honduran (they’re very similar and have adjoining if not overlapping territory).


I have read that Cocobolo contains color/oils that when applying a finish will bleed into other woods can this color/oil be used effectively to stain wood? Just wondering.


Eric how long can it take to grow one rosewood tree?


Can Burmese rosewood look similar to cocobolo?


Guatemalan Rosewood often does look like a more plain piece of cocobolo, although usually with more brown in the reds and a less tight ring structure.


Each and every board varies greatly in color and grain. You most likely got a piece of heart-wood, which from my experience is a hue of beautiful oranges, browns, greys, blacks, and even sometimes a hint of purple blue or green. very rarely any green. Sapwood boards are your darkers boards considering it’s still growing and very oily.

Hope my contributions on this page are helping,



Sapwood is a light straw color.


A few days ago I bought another blank made of Cocobolo but instead of a dark piece I got a light one, can this color change? What color could this shift to?


The color generally shifts darker with UV and O? exposure.


It is usually a bright yellow when cut. Turns to apeach, then ornge, then red, then maroon, then brown, often almost black. It depends on the extracyives in the wood. highly polished, it will usually be a dark brown with black streaks, sometimes it stays a bit of a maroon.


Where does the name, Cocobolo come from and what does it mean?~Trevor


From what I’ve heard, it is coco, like coconut, meaning in the sense of exotic, tropical, and bolo, meaning stick. So, kind of exotic wood, as close as i could decipher. I heard this from a Mexican who seemed rather knowledgeable inetymology.


According to the Oxford Dictionary, it derives from the Arawak word kakabali. If so it implies the Spanish probably encountered the wood during the early colonial period as their first contact was with Taino speaking people in the Arawak group. It also suggests these people either had cocobolo on the Caribbean islands (it’s long gone now if it was ever endemic there) or obtained it through trade with mainland Central or South America. In Panama today, cocobolo refers to baldness and probably isn’t a reference to the wood but rather a tongue in check reference to coco-coconut and bolo-ball.


When any fine particles of Cocobolo hit a mucus gland, it turns into a fine acid, due to the fact of the type of oil in the wood. So when it hits your nose the fine or semi-fine particles turn into a mild acid. In the most severe cases, very fine particles from sanding that make it into your lungs produce nitric acid in your lungs, which is very lethal. I was once routing mortises into a leg made of Cocobolo and had a bunch of rough dust fly up my nose and experienced the same thing you experienced. Of… Read more »

Not being facetious, but I find it fascinating how the different flora and fauna have produced self defense mechanisms like this and others. Fascinating biology.


I am not allergic to cocobolo but one day when was making a pen from it i began to experience an awful burning sensation in both nostrils and my eyes began to water. Am i allergic to this wood? P.S. I have worked with cocobolo twice, in a well ventilated shop.


well sometimes compromise must be made. And also, Cocobolo is getting very hard to find now-a-days, so not being able to work with it might not be as bad! I encourage to try to find a new way to turn it once again without getting the painful side effects. best of luck!



I’m not sure I buy the “hard to find” thing. You can go to Penn State Industries, Packard Woodworks, Craft Supply USA or any of a number of other sites and get it already cut into pen blanks and the cost isn’t any more than the other “exotic” (as compared to domestic) woods. I have turned many pens out of it and never had any issues with blisters or other nerve problems and I often wear short sleeves and never wear gloves when turning or sanding. I do wear a face shield to keep the dust and such out of… Read more »

Well, the precaution I have taken is to simply no longer work with Cocobolo. When I was working with it I didn’t experience respiratory problems, but the skin reactions were so severe (redness that felt like sunburn, itching that might last for a week, even blistering)that it simply wasn’t worth it. Add to that my wife’s “Are you CRAZY!” whenever I dream up some new scheme that might let me turn it again! The odds are simply stacked against Cocobolo (but I still haven’t managed to part with the wood I have on hand).


Dear Tom, Actually, Cocobolo saw dust is extremely dangerous in certain cases. Irritation at the sites where dust contacted has been reported in some cases, but when sanding, take every precautionary you can, especially wearing a dust mask. I had a first hand experience with router dust and finish sander dust. When fine-sanding, the moment the dust particles enter your lungs, the fluid in your lungs causes a chemical reaction that turns the fine dust into a very potent acid and can be very lethal. i personally breathed some in when working on a table made of Cocobolo, wasn’t aware… Read more »

I do simple turning, just reel seats and pens, but I do a lot of it, and early on I wasn’t as careful about dust as I should have been. Cocobolo was my favorite wood, and I turned a lot of it. Sadly, I am now allergic to it. As far as my body is concerned, it might as well be radioactive dust! And I am not a person prone to allergies, as far as I know my allergy to Cocobolo is it, although that sensitivity has made me be very careful around any wood in the Dalbergia family. This… Read more »


I made an entire side table out of Cocobolo. The only part of the table that is not Cocobolo is the drawer box, which is naturally-stained soft maple which gives the Cocobolo a very nice contrast.


Hi,do you think that BASIC Specific Gravity = Specific Gravity?,and
that Specific Gravity = Weight?or if the green lumber = dried lumber?please let me know what happen?.Some literature say Cocobolo Specific Gravity is 1.1 for that sinks in water.


@ Jim: Specific gravity is definitely wrong.

If you look at the average dried weight: 1,070 kg/m3, converting to units of g per cubic cm gives you a specific gravity of 1.07, which would sink in water.


Specific gravity wrong. Must be greater than 1 to sink in water.

Bruce Hodgman

I made some handles for kitchen knives from cocobolo back about 1970. No finish of any kind was placed on them. They are fine today in spite of almost daily use and daily washing. One of them shows a slight crack, however.
