London Pearl is looking for a buyer for what it claims is “probably” the largest round Tahiti necklace in the world.

The necklace’s pearls measure 18 – 20mm with good lustre. Pearls larger than 15 – 18mm are exceedingly rare and Daniel Vecht of London Pearl said it is the largest round necklace he has ever seen.

London Pearl said the necklace is a natural colour black Tahiti cultured pearl – with the pearls measuring 18 – 20mm. It believes it is the largest round necklace of its kind currently on the world market.

It said the Tahitian oyster is much smaller than the Australian South Sea oyster and therefore pearls of this size are very rare. The pearls all originate from the seas surrounding the island of Tahiti. London Pearl said the necklace it has composed is exceptionally large and because the pearls are so big, it said it has had to make the necklace longer than the standard 16 inches to make it wearable – this necklace is over 18 inches long, it claims.

London Pearl also announced it has also just made some white drop-shaped pairs that measure 13 x 22mm.
