ABOUT THE ITEM
Tridacna pearls are very rare, organic gems produced by the largest living bivalve mollusk from the Cardiidae family, known as the Tridacna gigas or Giant Clam. Tridacna clams can be found in the shallow waters of the Indo-Pacific, inhabiting coral reefs. They can live for up to 100 years, can grow as large as 4 feet across, and weigh up to 440 pounds! Natural Tridacna pearls are known for their porcelaneous appearance, sometimes displaying beautiful flame patterning.
Coral is a living marine organism that forms in branch-like structures in tropical and sub-tropical ocean waters. When coral polyps die, a dull, hardened skeleton remains that can be polished to a beautiful waxy luster. Most coral is white to cream in color but coral does occur naturally in several other colors such as red, pink, peach, black, orange, golden, blue, lavender, and angelskin. The most valuable coral, known as precious coral, falls within the red to pink color range.
This magnificent, 1-of-a-kind, multi-strand opera length necklace features 293 graduated precious coral beads fastened by a custom 18K white gold starfish clasp set with 3 carats of extremely fine quality pavé set round brilliant cut diamonds. At the center of the starfish is an extremely rare natural tridacna pearl. The pearl weighs 17.71 carats and displays eye-visible flame patterning!
