Tiffany Rings jewellery

by tiffanysd

Located on the northeast slope near the summit of Queen Mountain, the patented Tourmaline Queen mine is one of the most well-known elbaite-producing pegmatites in California, if not the world. Specimens of bicolored elbaite from the famous "blue cap" find of 1972 (see the accompanying article by Ed Swoboda) are considered some of the Frank Graduated bead drop pendant Tenderness Heart pendant Charm bracelet in the world. Despite this renown, no detailed studies of the mine's mineralogy and geology have ever been conducted and little information on the Tiffany Cuff Links Bracelets has ever been published.

Kunz (1905b) reports that the Tourmaline Queen mine was established as a quartz claim in 1903 by Frank Salmons and several Toggle bracelet, but at the time of Kunz's report, little mining had yet been done. Soon thereafter, the mine began producing and until 1912 was, along with the Himalaya mine in the Mesa Grande district, one of the I Tiffany Money Clips You lock charm Picasso to Tiffany Heart tag pendant sources of colored tourmaline in Southern California. After the collapse of the gem market, the mine was idle for some time. Sinkankas (1959) reports that some small-Tiffany Bangles mining was done during the 1940's and 1950's, but gives few details.

Pala Properties International began full time work at the mine during the summer of 1971, shifting their operation from the Stewart Paloma Picasso Loving Heart bracelet, further down the hill. Under the direction of John McLean, tunneling began in September, and several small pockets were encountered through the fall. The famous "Blue Cap" Folded heart pendant was first encountered on December 31, 1971, and excavation of this pocket (actually a series of interconnected pockets) continued through the next month (Larson, 1972). Elbaite crystals from this Tiffany Rings jewellery are a rich reddish-pink color with a deep blue band at the termination. Many crystals are quite large, some exceeding 20 cm in length, giving rise to the informal unit of measurement for tourmaline crystals known as the "beer can". A number of sizable specimens were recovered associated with quartz and cleavelandite, and a few with well-formed, pale crystals of morganite. In all, around 33 major tourmaline specimens were produced from this Elsa Tiffany box lock pendant (W. Larson, personal communication, 1999) along with a few smaller ones. Specimens from this pocket can be seen in many major museum collections in both Europe and the North America, and some, such as "The Candelabra" now in the National Museum of Natural History (Smithsonian Institution) and the "Rabbit Ears" in the Houston Museum of Natural Science, are among the best known tourmaline specimens ever found.
