Rare Gemstones II

Red Beryl Emerald is found in the Thomas Range and the Wah Wah Mountains of Utah. It occurs on rhyolite where it crystallizes under low pressure and high temperature along fractures or cavities of volcanic rhyolitic magma. Very few cut specimens exist.
Musgravite is a silicate mineral whose 3 main ingredients are beryllium (Be), magnesium (Mg) and aluminum (Al).

It was first found in the Musgrave area in Australia in 1993. Musgravite has been found in Greenland and Madagascar, but neither produces gem quality material. Two pieces of faceted gem-quality musgravite came from Sri Lanka in the mid 90s.
Grandidierite is a bluish green mineral found primarily in Madagascar. The first faceted specimen came from Sri Lanka.

The crystal is trichroic, transmitting blue, green and white light.
Painite was first discovered in the early 1950s in Myanmar.(Burma) Before 2005 less than 25 crystals were known, more have been unearthed since.
Garnets are found in many colors including colorless. The rarest of them all is the blue garnet, first seen in the late 1990s in Bekily, Madagascar. It changes color from blue-green in the daylight to purple in incandescent light due to it's high vanadium content. A 4.2 carat blue garnet gem sold at auction in 2003 for $6.8 Million.
Serendibite is a cyan colored stone that comes from Sri Lanka and Burma exclusively. It is composed of a complex formula of calcium, magnesium, aluminum, silicon, boron and oxygen. There were only three faceted (cut) specimens in existance ... of 0.35 carats, 0.55 carats and 0.56 carats.
Very few red diamonds have ever been found. One in every hundred million diamonds is a natural red colour. The Moussaieff Red is the largest Fancy Red diamond in the world at 5.11 carats. Discovered by a Brazilian farmer in the 1990s, the rough stone weighed 13.9 carats. The triangular brilliant cut stone was sold in 2001 for around $8 million. It is valued today at over $10 million.


The Rob Red Diamond is 0.59 carats and it still holds a special place in the diamond world. Rob Red is rated as the most intense red diamond ever discovered.
Jadeite is found in the Motagua Valley, Guatemala, and was used by the Olmec and Maya. Typically, the most highly valued colors of jadeite are the most intensely green, translucent varieties. The record price for a single piece of jadeite jewelry was set at the November 1997 Christie’s Hong Kong auction. The “Doubly Fortunate” necklace of 27 .5 mm jadeite beads sold for US$9.3 million.

Gold coins from 1715 treasure fleet found

48 gold coins from the 1715 treasure fleet have been discovered off the Florida coast.

Brent Brisben, who owns the shipwreck salvage company 1715 Fleet – Queens Jewels LLC, discovered the coins with a four-member crew as part of his excavation quest Saturday. A half hour into their quest, the crew was only 100 feet away from the shore when they discovered the coins.

Brisben is estimating the value of the coins at $250,000, but says his archaeologist has to come in and provide the full value. He estimated that each coin is worth $4,000 to $5,000. The oldest one dates back to 1697, and the newest one 1714, he said.

On July 31, 1715 eleven of the twelve Spanish ships sailing from Havana to Spain with royal treasure were wrecked by a violent hurricane on the east coast of Florida from St. Lucie to Cape Canaveral.

Seven of these Spanish Treasure laden ships were scattered over the reefs from south of Fort Pierce to the Sebastian Inlet. Spanish coins of all types (gold and silver) started to be found on the beaches in the 1950s after strong nor'easters or a violent hurricane. This part of Florida's Atlantic east coast quickly became known as the Treasure Coast.
The (El Senor) San Miguel - was a 22 gun NAO Class(Fast Carrack). It very likely contained a significant portion of the treasure. It is believed the ship separated from the fleet the day before the storm struck and the wreck has never been found.

It is believed only a small fraction of the treasure of the lost 1715 Treasure Fleet has been recovered.
1715 Fleet ships believed to have been found are:

1 - Nuestra Senora de la Regla
2 - Santo Cristo de San Roman
3 - Nuestra Senora del Carmen
4 - Nuestra SeƱora de La Popa
5 - Nuestra Senora del Rosario
6 - Urca de Lima
7 - Nuestra Senora de las Nieves
- Ships of the 1715 Fleet never located are the:

8 - Maria Galante
9 - El Senor San Miguel
10 - El Cievro
11 - Nuestra Senora de la Concepcion

12 - Griffon made it safely and went on to France



VERO BEACH — Bonnie Schubert couldn’t believe her eyes when, about 1,000 feet off Frederick Douglass Beach near Fort Pierce, she came face to face with a solid gold statue of a bird that had lain under the Atlantic Ocean exactly 295 years and 15 days.

“I remember asking myself, ‘Is this real?’” Schubert recalled Wednesday as the 5.5-inch-tall statue she found Aug. 15 was revealed to the public at her home in the Vero Shores neighborhood of Vero Beach.“The Bird,” as it’s come to be known, is real all right.

So is it’s $885,000 appraised value.

The statue was aboard one of 11 Spanish ships laden with treasures from the New World that were bound from Havana to the court of King Phillip V before encountering a hurricane July 31, 1715, and sinking off the Treasure Coast.

2.95 carat diamond found in Arkansas

Terry Staggs of Kentucky was visiting the Crater of Diamonds State Park in Arkansas on July 4th when he saw something in the dirt sparkle in the sunlight. It turned out to be a 2.95-carat, champagne-colored diamond, according to United Press International. Mr. Staggs has named it the Patriot Diamond in honor of the day it was found.
The Crater of Diamonds is a 911-acre state park in Murfreesboro, Arkansas that contains a 37.5 acre plowed field in which visitors can literally dig for diamonds.
It's the world's only diamond-bearing site that's accessible to the public.

The largest diamond ever discovered in the US, the 40.23-carat Uncle Sam, was found there in 1924. It was cut twice, resulting in a final 12.42-carat (2.484 g) M-color, VVS1 clarity emerald-cut diamond. In 1971, the Uncle Sam was sold for $150,000.
