Size (L x W x D). 10.16 x 10.29 x 7.96 MM. Tanzanite is a stunning, rare, and valuable gem of mineral Zoisite.It was discovered in 1967 in the Merelani Hills of Northern Tanzania, Africa. Tanzanite is a single source gemstone with deposits found exclusively in an 8 square mile (20 square kilometers) area just north of Arusha.
1000 times rarer than diamonds, investors as well as jewelry connoisseurs around the world have created far more demand than can be supplied by the few operational mines that remain. Most of you understand that tanzanite will "mine out" in the near future and though we cannot be sure exactly when this will happen, we can say with certainty that prices are climbing steadily. A quick trip to the jewelry store will confirm this. Tanzanite is considered the most important gemstone discovery in 2,000 years. Exquisite and unique, the colors of tanzanite range from soft lavenders and sea greens to investment quality deep sapphire- blue/violet and violet/blue with tertiary flashes of bright red.Highly pleochroic, when viewed from different angles and in changing light, tanzanite's colors shift and blend as if seeing shades of blue and lavender at once. Tanzanite scores 6.5 to 7.0 on the MOHS hardness scale, and is well suited for use in all types of jewelry and is favored by many of today's acclaimed fine jewelry designers. A valuable addition to your jewelry collection, we recommend gentle wear, no ultrasonic cleaning, and separate storage to avoid scratches. A gemstone like no other, tanzanite will soon disappear into private collections rarely available or affordable. We are currently able to offer you investment quality natural tanzanite at prices that are well below today's market value, an opportunity that we hope you will take advantage of while it lasts. It is our pleasure to provide you with the information you need to make an informed decision. Thank you for your patronage.
