Investment Grade Tanzanite
This class of Tanzanite belongs to the very top 1% mined and is very rarely seen in the market. We specialize in sourcing the few Tanzanite mined that meet this grade using our 20 year relationship with the miners and our proximity to the mines. Out of a thousand carats mined literally 9 or 10 will be of this grade. These colors are extremely rare and their rarity makes them attractive to investors.
This gorgeous Tanzanite began its formation on the slopes of Mount Kilimanjaro about 550 million years ago. Heated ground waters circulated through rock fractures, dissolving minerals from the surrounding rocks and redepositing them in open spaces like fractures. Here as the rock folded with time, the heat and pressure grew to a level where it was possible for Tanzanite to form.
This remained constant for the many millions of years between that time and the time it was discovered by man. Any changes in the environment during this time would have meant that this Tanzanite would not have formed – the heat and pressure and mix of chemicals must have stayed constant for the entire 550 million years. Hundreds of millions of years later it was chiseled from the crevice within which it had lain for so long and carried to the surface by miners in Block D of the Merelani Tanzanite mining area.
