Aqua Aura Kyanite – A New Twist on Vapor Treated Natural Stones

We have seen so many varieties of quartz coated with titanium, gold, indium and iron. Coated material from Brazil and Arkansas were standard, then, geodes, cactus quartz from South Africa and even some zeolites started showing up.

Yet, it was surprising to see Aqua Aura Kyanite blades.

These showed up at a gem show we were visiting and I asked the vendor to send us some photos of these beautiful stones.
The dealers, Cinderhill have a great selection of natural stone pendants. They told me that these are a type of kyanite from brazil that is black. Coating it with titanium vapors makes these clusters vibrant.

Sotheby’s Important Jewels Brings in Over $16 Million

Today’s auction of Important Jewels at Sotheby’s New York totaled $16,383,856 – well above its $14 million low estimate – and was 79.3% sold by lot. This marks another strong total for our jewelry sales in New York, coming just $100,000 shy of last year’s record for a September jewelry auction at Sotheby’s.
“We were very pleased with the solid results of today’s sale,” commented Gary Schuler, Head of Sotheby’s Jewelry department in New York. “We saw particularly strong prices for unique color diamonds, led by the fancy light pink diamond that soared to $1,426,500 above a high estimate of $700,000. While many of our top ten prices came from American trade buyers, both signed jewels and stones under 10 carats brought spirited bidding from collectors worldwide. Jewels from the estate of Kitty Carlisle Hart, which we were delighted to offer, doubled their overall low estimate and were led by her beautiful art deco diamond sautoir that achieved $146,500 (est. $60/80,000). And in a continuation of a trend we have observed in recent years, natural pearls remain a strong segment of today’s market.”

“We now look forward with great excitement to next week’s sale of Property from the Estate of Brooke Astor, which will offer a wonderful selection of the icon’s personal jewels in the Tuesday afternoon session.”
