Tanzanite

Tanzanite is the blue/purple variety of the mineral zoisite. (a calcium aluminium hydroxy silicate) It was discovered in the Mererani Hills of Manyara Region in Northern Tanzania in 1967, near the city of Arusha and Mount Kilimanjaro.

This is only known source in the world and has been depleted over the years. Naturally-formed tanzanite is extremely rare.
TanzaniteOne Mining Ltd. is a gemstone mining company which exclusively mines the blue gemstone.

TanzaniteOne Mining Ltd is a fully owned subsidiary of the London AIM listed resource company, Richland Resources.( AIM : RLD )
Tanzanite is a relatively new gemstone in the world of gemology and jewelry. Since its discovery, tanzanite has sold for as little as $20 per carat and as much as $1,000 per carat or more, for gem-quality, finely coloured stones.

That price may seem like a bargain in time, as tanzanite is a single-source gemstone and that source is expected to be mined out within the next 20 to 30 years based on the latest mining information.
Tanzanites are typically blue or violet-blue, but they can also be rare greenish and greenish-blue shades. Tanzanite is a highly pleochroic gem, meaning it can appear blue from one angle and violet or violetish-blue from another.

Vanadium is the main coloring agent required to produce the rich blue-violet colors that are so highly prized.

Ancient gold of Kuban

Since the start of construction of the Olympic venues, over a dozen archeological expeditions have been held, and close to 400 artifacts have been handed over to the city's history museum. "The construction of the Olympic venues in Sochi over the past five years has triggered large-scale archaeological excavations previously unseen in this resort city," said Alla Guseva, Deputy Director for Research at the museum.
In October 2013 the museum unveiled the Ancient Gold of Kuban and the Black Sea Region exhibition as part of the Cultural Olympiad's Year of Museums. This is the first exhibition to feature artifacts unearthed during the Olympic construction.

The excavations in the Imereti Valley started in the wake of the Olympic construction. Previously, the area was considered unattractive for archeological expeditions. However, the first excavations have demonstrated that the area has been populated since ancient times.
The Bosporan Kingdom was an ancient state located in eastern Crimea and the Taman Peninsula, on the shores of the Cimmerian Bosporus (now known as the Strait of Kerch). It was named after the Bosphorus, also known as Istanbul Strait, a different strait that divides Asia from Europe.

The Bosporan Kingdom was the longest surviving Roman client kingdom. The prosperity of the Bosporan Kingdom was based on the export of wheat, fish and slaves. The profit of the trade supported a class whose conspicuous wealth is still visible from the newly discovered archaeological finds.

Van Cleef & Arpels - High Jewels

Van Cleef & Arpels is a French jewelry, watch, and perfume company.
It was founded in 1896 by Alfred Van Cleef and his brother-in-law Salomon Arpels. Van Cleef & Arpels are known for their expertise in precious stones and for a gem-setting procedure known as the Mystery Setting.

Since its inception, Van Cleef & Arpels has been synonymous with royalty, the famous and the affluent, providing the elite with exceptional and unique pieces of jewellery.
The Mystery Setting is a proprietary mounting technique for gems. There are no visible prongs; instead the individual stones are hand grooved to fit into a mesh of gold or platinum wire. This type of setting was perfected by Van Cleef & Arpels in the 1930s.
