You can tell if a black pearl is dyed by checking for dye buildup in the drill hole (darker color, white nucleus showing), looking for unnaturally uniform color and plastic-like shine (natural pearls have variations and depth), spotting tiny black speckles on the surface, and noting if the color seems too vibrant or lacks the natural rainbow overtone. Dyed pearls often appear too perfect and lack the natural luster and subtle surface imperfections of genuine Tahitian or high-quality freshwater pearls, which feel cool and heavier.
How to tell natural vs dyed? 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.
Pearls with dye treatments are worth less than those with natural colours.
While pearls can naturally occur in every hue and be very saturated in color, pearl colors can be treated to alter their appearance. The most common color treatment is dyeing, and it is more common with freshwater pearls than saltwater pearls.
Natural Black pearls (uncultivated) are extremely rare and are found in about 1 in every 10,000 oysters. In an effort to preserve the species, it is illegal to dive to find natural pearls.
Is the color on dyed pearls permanent? The dyes used to color cultured pearls can fade over time. Because organic pearls are porous, they often absorb human oils, makeup and perfume, which can stain and alter the color of the pearls and the dyes used to color them.
Black pearls generally fall within a price range of $100 to $10,000 per pearl or more. The variation depends on whether the pearls are natural or cultured, size, and quality. For example, smaller cultured black pearls might cost a few hundred dollars, whereas large, flawless specimens can fetch thousands.

Ultraviolet Light Test
When exposed to ultraviolet (UV) light, real pearls may fluoresce or glow slightly, depending on their origin. Imitation pearls generally do not fluoresce or may exhibit an unnatural glow.
Another way to check if your pearls are real is to submerge them in vinegar. If they are real, the pearls will form bubbles due to the chemical reaction of vinegar acid and calcium carbonate which is the primary chemical that a real pearl is made of.
Methods of Authenticating Black Pearls
Real black pearls sometimes exhibit subdued green, purple, or blue overtones. The Tooth Test: Run the pearl lightly between your teeth. Fake pearls will feel silky; real pearls will feel slightly rough.
The most expensive pearl colors are often deep, rich hues like Golden South Sea (especially 24k deep gold), rare Peacock Tahitian (dark green/blue/purple overtones), and intensely pink or pink-overtoned White South Sea pearls, with value heavily depending on rarity, luster, size, and lack of blemishes, rather than just the base color itself. While white and black are common, specific, saturated, and rare overtones within these categories command the highest prices.
Contrary to popular belief, imitation pearls very rarely turn yellow due to their composition of plastic and ceramic. Pearls that begin to yellow indicate that they are organic and subject to change.
