South Sea Pearls (AKuya), small sizes 6mm to 8 mm :
Cultured in Japan and China, this variety is well known for it's use in Jewelry.
The akoya oyster is the smallest pearl-producing oyster used in pearl culture today. Akoya pearls also tend to be small, ranging in size from about 2 to 10 millimeters. They also tend to be the most consistently round and near-round pearls, making them ideal in terms of matching for multi-pearl jewelry such as strands and bracelets.
- A string of 8 mm white pearls top quality, top luster would cost around 900 USD
- A similar string but of other color, and lower grade would cost around 500 USD
- Available by piece
- Available colors : White, Black, Grey

(Photos)
- A string between 10 mm and 12 mm white pearls in gradient of good quality and luster would cost around 3.000 to 3.500 USD.
- A string between 8 mm and 10 mm white pearls in gradient of good quality and luster would cost around 1500 to 2.500 USD
- A stringusing a single size (like all pearls 10 mm) would be 20% more expensive because it requires a selection at th farm and constitutes a special order. In 9 mm maybe they would surcharge less, but 10 mm is the most depended size, s if everyone wants this size they will not be able to matche the rest of the sizes in gradients, being short in 10 mm.
- For South Sea Pearls in bigger sizes we do not supply strings.

South Sea pearls when they are bought in pairs or as a single pearl tend to be more expensive because mostly prefect in shape and sold as a unique pearl or unique assortment. The price will mainly be influenced by the color and the luster.

- Bigger sizes are exceptional and prices are to be discussed case by case.

EXAMPLE
=======

Please consider this example of design that we proposed to our customer in Bangkok :

This is a South Sea pearls necklace coming in a set with a pair of white pearls and princess diamonds earrings designed by us for a Customer in Thailand. The lady didn't have pierced ears and needed to have her earrings custom made.
The entire set, custom made was sold $3700 which wouldn't cover a similar pearl string (without the earrings) bought from a specialized wholesaler here in Bangkok, because we bought it directly from the farm in Japan.

Description of the necklace :

Color: white
Size: 10 to 11 mm gradient sizes
Luster: good to very good
Quality: perfect rounds, very few surface accidents

6 Diamonds Princess cut :
Clarity: VVS2
Color: F
Weight: 0.36 carats


Such items are ordered from Japan by order basis and should be paid up front because we cannot return them unless the quality does not correspond to the description. Therefore our customer needs to rely on our judgment for the quality and use the grading classification mentioned above (Shape, surface, luster) to describe his requirement.
Similar products are available in Thailand from wholesalers (faster delivery, but higher price than bought from the pearl culture farm)
Our supplier has a very strict and well organized classification system just like we would expect from a Japanese.
