Here is a quick run down on the 4 main types of cultured pearls you'll encounter while pearl shopping.
AKOYA PEARLS:
When most people think about white pearls they are thinking about Akoya pearls- the are the classic white pearls. They are grown in saltwater off the coast of Japan.
Mikimoto and Tiffany's sells primarily cultured Akoya pearls.
If you want classic white, round pearls with high luster, BUY AKOYA PEARLS.
FRESHWATER PEARLS:
If someone says they are offering "cultured pearls" but doesn't tell you a type of pearl, 9/10 times they are cultured freshwater pearls.
These pearls come in white, peach, lavender, and recently some very EXCITING EXOTIC COLORS.
Freshwater pearls used to be very low quality, but today freshwater pearl farmers are producing affordable pearls that rival the very best saltwater pearls.
My GEM GRADE FRESHWATER PEARLS are exceptional quality at about 1/3 the price of Akoya pearls.
BLACK TAHITIAN PEARLS:
These are the only naturally "black" pearls. It's important to understand that the term "black" is used to describe dark colored pearls, including silver, gray, green, blue & purples -- not necessarily a true black.
They are grown in saltwater "atolls"off French Polynesia and Fiji. They aren't actually black but instead they are dark shades of gray, green, blue and purple.
They are large exotic pearls that just 20 years ago would have sold for $100,000/strand. Today with increased production the same strand can be purchased from me for $3000.
