Our Pearl Types

The four pearl types we use in our jewelry:

Akoya Pearl Akoya Pearls
Considered the classic among cultured pearls, Akoya pearls are primarily round or oval in shape and most commonly measure 5 to 8mm. They are cultured in many parts of the world, but most commonly in southwestern Japan and China. Their colors range from pinkish white to creamy shades of silvery blue.
Chinese Chinese Freshwater Pearls
Freshwater pearls are grown in an amazing variety of delicate shapes, ranging from round and oval to button, drop and baroque. Their colors vary from pure white to orange and rosy violet.
Tahitian Pearl Tahitian Pearls
Tahitian pearls are synonymous with magic and perfection. Most come from the atolls and lagoons of the South Pacific. They tend more toward drop shapes than round and vary in size from 8 to 14mm, and some can occasionally reach 16 or even 18mm. They can be black, silver, dark or light gray. The rarest color is "peacock green" – the greenish black color of a peacock feather.
South Sea Pearl South Sea Pearls
The South Sea Pearl is unquestionably the rarest and finest cultured pearl in the world. No other pearl can equal its natural beauty and size. South Sea pearls range in size from 9mm up to 20mm, and come in many varied shapes and colors. Among all of the South Sea pearls, the Australian are especially prized and generally more valuable.
