“Black Tahitian pearls” are natural-color Tahitians from the black-lipped oyster.
True jet black pearls do not exist; most show dark gray to green, blue, purple, or peacock overtones.
Black Akoya & Freshwater pearls are always dyed or treated
Dark "black" pearls are often less desirable than dark green, purple or blue
Buy from sellers who disclose pearl type and treatments.
For centuries the black pearl has captivated pearl collectors and treasure hunters alike. With its dark body color and mesmerizing overtones and iridescence, the black pearl is both enchanting and full of mystique.
Up until recently a strand of exotic black pearls could fetch $150,000+. Thankfully today consumers have several options if they wish to wear these mysterious black gems. But still the question often comes up "why are black pearls black"?
Black pearls are Tahitian pearls that come from the black-lipped Pinctada Margaritifera oyster. You can also find “black” Akoya or “black” Freshwater pearls, but they’re always dyed. Tahitian pearls are the only naturally black pearls.
Yes, Black pearls are real. Tahitian pearls are often called black pearls because of their natural, untreated, dark body colors.
Within the pearl industry, the term "black" is used to describe any pearl with a dark body color. In reality a natural, truly black body color just doesn't exist in the world of pearls. Instead, within the Tahitian pearls what we see are dark greens, blues, purples, silver, gray and the most coveted coloration "peacock".
Below is a small lot of very high quality Tahitian Pearls. Notice the wide range of colors, but no jet-black pearls.
Natural black pearls are made when an irritant enters the shell of an oyster. Cultured black Tahitian pearls are made by inserting a bead nucleus into a black-lipped Pinctada Margaritifera oyster.
Interestingly the color of pearl produced through culturing is influenced by the host oyster’s shell color. If the inside of the Tahitian black-lipped oyster displays greens or blues, these colors are likely to show up in the pearl. However, Mother Nature is still in charge and there are no guarantees in pearl farming - which is what makes the rarest colors so valuable.
Other black pearls are made by dyeing or irradiating white pearls, such as white Freshwater or white Akoya pearls.
GIA treats “black pearls” as mostly cultured pearls from the black-lipped oyster Pinctada margaritifera, with production centered in French Polynesia; natural blacks exist but nearly all on the market are cultured. Color is defined as body color plus overtone; the most prized look is a greenish black often called peacock. Grading follows five trade factors: color, luster, shape, size, and surface. Typical sizes average 9–12 mm, with larger rounds rare.
On treatments and testing, the lab notes long use of silver-salt dyeing on Akoya to imitate black, and gamma irradiation that darkens Akoya by coloring the freshwater bead nucleus. To separate natural color from treated, GIA relies on non-destructive lab work: long-wave UV fluorescence patterns, X-ray fluorescence to detect silver, X-radiography to reveal nuclei and “reversal rings,” plus careful visual and microscopic checks. Definitive calls require a well-equipped lab.

You can find natural black pearls in French Polynesia – these are the Tahitian pearls.
French Polynesia is renowned all over the world for its production of beautiful, dark and very colorful Tahitian pearls. Not only are the colors of these pearls natural and unique, but pearl farming in French Polynesia is also a completely sustainable practice. Which makes these “black” pearls the only "green" gems in the world.

When culturing a Tahitian pearl, technicians insert a small square of donor mantle tissue with a mother of pearl shell bead into a Pinctada Margaritifera oyster. The mantle tissue influences the pearl's color, depending on colors present in the shell of the donor mollusk. It may lead to shades of plum, green, blue, cherry or gray depending on the tissue used.
As well as body color, black Tahitian pearls often exhibit strong overtones of green, cherry, aubergine or peacock. The end result is a pearl that boasts a dark body color and colorful overtones that are only present in black Tahitian pearls.
“When shopping for Tahitian pearls, look for dark green body colors with peacock overtones. This is the ultimate combination that never goes out of style”

Black Akoya pearls are dyed to achieve this color. The dyeing process leaves pearls that are incredibly uniform in color, and very saturated.
Black Freshwater (China) and black Akoya pearls (Japan) are produced with dyes and treatments. Black color does not exist naturally in these two types of pearls.
Jewelry technicians employ dyes or irradiation to transform light colored pearls into black pearls. One treatment involves an Akoya or Freshwater pearl being dipped or soaked in a silver nitrate solution which darkens the pearl's nacre like a dye. Sometimes irradiation is also used. This process employs gamma rays that darken the nucleus of the pearl. While these processes are artificial, they are considered permanent and often produce fantastic body colors that many jewelry lovers find appealing.
Color treated Freshwater pearls are near jet black pearls with blue, green, violet, copper and sometimes even peacock overtones. Similarly, color treated Akoya pearls are deep black pearls with strong green or blue overtones.
Dyed black Freshwater pearls look nice, but up close you can sometimes see tiny black speckles where the dye has accumulated unevenly.
Yes, you can tell them the difference, but it isn't always easy... Treated pearls tend to be far more uniform in color than Tahitian pearls, which usually show some natural variation.
Another clue is to inspect the drill hole of the pearl. When pearls are dyed, the color will naturally collect in this space and show slightly darker. Looking directly in the drill hole you may also see a darkened nucleus, but this can be hard spot on smaller pearls. No such variation in color will be noticeable in natural black Tahitian pearls.
In the last few years, we've witnessed a flood of online sellers selling dyed Freshwater pearls as Tahitian pearls. We've seen this on eBay, Amazon and even some big name online jewelry websites.
Reputable jewelers, like Pearls of Joy, will always disclose whether the pearl is a Tahitian or dyed Akoya or Freshwater pearl. In any case, it's always best to do your own research to better understand exactly what it is you're purchasing.
For jewelry buyers, understanding the value of black pearls as well as where to buy them is an important consideration.

Size and luster move price fastest
Dyed Akoya or Freshwater strands are cheaper and more uniform
Common Tahitian sizes (8–10 mm) run a few hundred to several thousand depending on luster, surface, and matching. Large clean rounds 11–13 mm+ can easily fetch $10,00.+
Entry strands ~$300–800; fine quality often $800–5,000+
Chips, dull luster, or poor matching drop value fast
Natural Tahitians show varied overtones and a clean drill hole that matches the body color. Dyed pearls often look uniformly dark with a darkened drill hole.
