This truly outstanding 10.1 carat Tanzanite center stone spectacularly showcases the beautiful violet blue color for which the stone is known. The intense color of this Tanzanite is further magnified by three tiers of dazzling white diamonds surrounded by luxurious 18 kt white gold.  This extraordinary and opulent show-stopper is sure to turn heads.

Gordon’s Design Notes: I first came across a vendor specializing in tanzanite gemstones at the Thai Gem Show in Bangkok. I immediately became enchanted by the rich blue hue with a hint of purple of this amazing 10.1 carat tanzanite gemstone. I had to have it. I decided such a regal stone must be conspicuously displayed, so I chose to place it on a throne atop 3 steps of sparkling diamonds. This necklace is impossible to miss.

Design Inspiration: Erin

Price: $24,300 NOTE: This tanzanite piece can be bought in two additional arrangements, as a pendant (P-10) or with a 22 inch adjustable length chain (N-10-22-Adj). Details above.

When dressing, fine jewelry should always be the last item put on and the first item taken off to minimize the gemstones coming into contact with perfume, lotions, hair products, etc.
Care Continued:
Protect your jewelry from impact against hard surfaces and avoid contact with abrasive surfaces. All gemstones, including diamonds, can chip, scratch, or abrade under the right circumstances.
Care specifics:
Tanzanite is particularly vulnerable to hard blows, so it should be worn with care. Avoid ultrasonic and steam cleaning.
Care Specifics Continued:
With wear, rhodium plating can thin to the point where a yellowish tinge may show through. Periodic re-coating with rhodium will revive the original bright white color. Re-plating does not damage the gemstones.
The best method for cleaning all your jewelry is to soak each item in a mixture of lukewarm water and gentle dish washing liquid followed by a very light cleaning with a soft child’s toothbrush.
Cleaning Continued:
Place the item(s) in a fine mesh strainer and rinse to remove the soap. Gently place each item on a lint-free cloth and softly pat them dry. See the Care and Cleaning Section of the Website for a more detailed explanation.
