(You save )

This truly outstanding 10.1 carat Tanzanite center stone spectacularly showcases the beautiful violet blue color for which the stone is admired. 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. Not only is this necklace beautiful, but with a chain that’s completely adjustable up to 22 inches in length, you’ll find it extremely practical. This allows the pendant to be positioned so it lays exactly where you want. No matter the outfit, your necklace will be perfectly placed! NOTE: Besides this arrangement (as a necklace complete with a 22 inch long adjustable chain) this tanzanite beauty can be purchased in 2 additional different arrangements:

  • As a pendant with no chain. If you already own the perfect chain and don’t need another one. To learn more, go to item “P-10” under the “Pendant” sort in the product menu.
  • As a necklace complete with a 20 inch fixed length and slightly thicker 18 KT gold chain. For the person who doesn’t require the flexibility of the adjustable chain, but wants to purchase this outstanding piece as a necklace. Go to item “N-10-20-Fixed” in the “Necklace” sort

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.

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 Continued:
Tanzanite is particularly vulnerable to hard blows, so it should be worn with care. Avoid ultrasonic and steam cleaning.
Care 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 Education & Resources Section of the Website for a more detailed explanation.
