E505 Beautiful Tanzanite 2.88-Carat, Gemstone Ring:


The ring is the 20th Century; the setting is made for this amazing brilliant just under 3 carats of natural Tanzanite. The gemstone is held by 10 strong prongs, the setting and band are made of 10 karat yellow gold.
There are Tanzanite's that are lab grown or coated to look like a Tanzanite. I have sent this ring to a Gemstone Lap in Philadelphia, to be refracted and tested to be certain it is a true natural Tanzanite.
Meaning of Tanzanite:
Tanzanite is a stone of transmutation, shifting from lilac-blue to sapphire blue and into deep blue-violet. In faceted form it is stunning, celebrated as the Gemstone of the 20th Century and first promoted by the New York jewelers, Tiffany & Co. who created magnificent pieces to showcase this stone. Tanzanite is blue Zoisite, a calcium aluminum silicate, and forms in prismatic, usually striated crystals, transparent to slightly opaque, and ranges in color from deep ultramarine blue to light violet-blue. The most coveted crystals are a saturated blue with a hint of purple around it. In raw form Tanzanite occurs as blue, purple, brown and yellow. In artificial light it appears as an amethyst blue.

Manuel de Souza, a tailor and part-time gold prospector living in Arusha (Tanzania), found transparent fragments of vivid blue and blue-purple gem crystals on a ridge near Mererani, some 40 km southeast of Arusha. He decided that the mineral was olivine (peridot) but quickly realized that it was not, so he took to calling it "dumortierite", a blue non-gem mineral. Shortly thereafter, the stones were shown to John Saul, a Nairobi-based consulting geologist and gemstone wholesaler who was then mining aquamarine in the region around Mount Kenya. Saul, with a Ph.D. from M.I.T., who later discovered the famous ruby deposits in the Tsavo area of Kenya, eliminated dumortierite and cordierite as possibilities, and sent samples to his father, Hyman Saul, vice president at Saks Fifth Avenue in New York. Hyman Saul brought the samples across the street to the Gemological Institute of America who correctly identified the new gem as a variety of the mineral zoisite. Correct identification was also made by mineralogists at Harvard University, the British Museum, and Heidelberg University, but the very first person to get the identification right was Ian McCloud, a Tanzanian government geologist based in Dodoma.
Scientifically called "blue zoisite", the gemstone was renamed as tanzanite by Tiffany, who wanted to capitalize on the rarity and single location of the gem, but who thought that "blue zoisite" (which might be pronounced like "blue suicide") wouldn't sell well. Tiffany's original campaign advertised that tanzanite could now be found in two places "in Tanzania and at Tiffany's".
The size of the rings band is size 8 1/8 which can be resized if needed. The Tanzanite gemstones sell for $1100.00 per carat in todays marked. When the mines are depleted the value of the gemstone will go up significantly. So they are an investment gemstone.
