Thousands of pearls found in recovered treasure

KEY WEST, Fla. - Shipwreck salvors discovered thousands of pearls Friday after opening a small, lead box they said they found while searching for the wreckage of the 17th-century Spanish galleon Santa Margarita.

Divers from Blue Water Ventures of Key West said they found the sealed lead box, measuring 3.5 inches by 5.5 inches, along with a gold bar, eight gold chains and hundreds of other artifacts earlier this week. They were apparently buried beneath the ocean floor in approximately 18 feet of water about 40 miles west of Key West.

"There are several thousand pearls starting from an eighth of an inch to three-quarters of an inch," said Duncan Mathewson, marine archaeologist and partner in Blue Water Ventures. "We have no idea exactly how many, because we haven't counted them yet."

James Sinclair, archaeologist and conservator consulting with Mel Fisher's Treasures, Blue Water's joint-venture partners, said the pearls are very rare because of their antiquity and condition.

"Pearls don't normally survive in the ocean very well once they've lost the protection of the oyster that makes them," Sinclair said. "In this instance, we had a lead box and the silt that had sifted into the box from the site of the Margarita, which preserved the pearls in a fairly pristine state."

An initial cache of treasure and artifacts from the Santa Margarita was discovered in 1980 by pioneering shipwreck salvor Mel Fisher. The pearls will be conserved, documented and photographed in an archaeological laboratory above the Mel Fisher Maritime Museum in Key West.

"Until they're properly cleaned and conserved we don't know their value, but it would seem they would be worth upwards of a million dollars," Mathewson said.

Pearls and Global Warming

Pearl farmers live in some of the world’s most beautiful places: sheltered lagoons with pristine clean waters and some of the world’s highest biodiversity. But this closeness to nature also means that they are also one of the most vulnerable industries to climate change. At this year’s GIA Gemfest in Basel, which featured leading pearl producers from all over the world, the topic of the threat of global warming to the quantity and quality of pearl production was one of the interesting topics raised. more...

Mikimoto introduces South Sea grading system


New York—Pearl house Mikimoto has created a grading system for its South Sea cultured-pearl collections.

The proprietary system, similar to Mikimoto's Akoya grading system established in 1974, gives each pearl a grade based mainly on the luster and surface perfection of the gem. The system does not reflect a pearl's shape, size and color, but those factors do contribute to the pearl’s value.

Pearls receive grades from A to AAA. A AAA South Sea pearl represents the most perfect possible pearl.
