Natural Conch Pearl & Antique Rose Cut Diamond Ring in 18K Gold
This gorgeous ring features an EXTREMELY RARE, natural conch pearl framed by antique rose cut diamonds, in 18 karat gold.
A conch is a medium to large-sized marine gastropod from the Strombidae family, known as the Strombus Gigas, or Queen Conch. Queen Conchs are found off the coast of the Bahamas, Florida Keys, Caribbean Islands and Bermuda where they're harvested for their delicious meat. Popular conch dishes include conch fritters, conch salad and conch chowder. Very rarely, a natural pearl will be found inside a conch shell.
Only 1 out of every 10,000 to 15,000 conchs will produce a pearl. Only 1 out of every 100,000 to 150,000 conchs will produce a gem conch pearl! These natural conch pearls are produced when an irritant, such as a grain of sand, enters the mollusk. As a defense mechanism, the conch will coat the irritant with a calcium carbonate, over time producing a porcelain-like pearl.
While pink is the most valuable color, conch pearls can range in color from pink to red, orange, brown and white, sometimes displaying a characteristic known as flame structure that appears as a fire burning on the pearl's surface. This flame-like or silk-like appearance is due to a phenomena known as chatoyancy.
This conch pearl displays a silky, gem flame structure within its vibrant pink hue! It measures approximately 5.35 x 4.22mm and weighs exactly 0.69 carat.
The pearl is framed by a halo of twelve (12) natural antique rose cut diamonds. These diamonds total approximately 0.06 carat.
The die struck ring shank is signed and hallmarked, "PSP 18K".
The ring is presently a size 6.25 and has a gross weight of 4.1 grams.
Please Note: The conch pearl is set in a genuine antique head, which has been attached to a more modern 18K gold ring shank.
