Out of the Blue

Carrie Underwood sings at CMA awards December 15, 2014

Sutra sapphire earrings

Colors don't have to 'pop' as fashionistas are always wont to say. Sometimes the strength of a statement is in--more is more. Carrie Underwood sang at the recent CMA awards in a vivid blue gown and accessorized by Sutra asymmetrically designed pendant earrings. Both are intense blue and drive home the power of sapphire's bold hue.

Sapphire and ruby are kissing cousins--both are exactly the same gem mineral species, being corundum. What makes their coloration different is the inclusion of chromium in the case of ruby to turn the stone a bright crimson. With sapphire, it's iron, titanium and chromium which are responsible for the lush cobalt tint. 

When considering what accessories to pair with an outfit, don't forget the monochrome statement which can be a bold and memorable choice.

Precious Pinks

Christie's New York Magnificent Jewels sale December 10,  2014
Christie's New York announced tonight the sale of an oval cut fancy light pink Golconda diamond of 21.30 cts in their Magnificent Jewels sale. The anonymous winning bidder carried it off for US $4,253,000 including buyers premium.

It's right on par with the pre-sale estimate which was between 4-6 million dollars.

The Golconda moniker describes diamonds  devoid of nitrogen--an uncommon and highly desirable trait for a diamond. They are classified as Type IIA and coveted because nitrogen contributes a slight yellowish cast to diamonds. They also tend to be very clean stones. But Golconda is also a place; the Golconda Fort in India was the sole source of diamonds for thousands of years prior to their discovery in Brazil and South Africa.

Black Friday Every Day

Spirit of De Grisogono - World's largest black diamond

Once upon a time in a far away land, carbonado, or black diamonds were routinely chucked out in favor of the colorless 'white' variety. Thankfully for black diamond lovers everywhere, things have done a one-eighty in that department.

Under microscopic scrutiny, black diamonds may actually be one of several deep toned hues, like intense brownish black or gun metal green.A truly semi-transparent straight black diamond is a rarity inside a rarity.

A distinguishing trait about all blackies is their phenomenal toughness. We know that all diamonds are exceedingly hard, rating 10 on the Mohs scale. But black diamonds go one step further. Their extraordinary toughness is the result of criss-crossed fissures in their lattice structure, but you knew that. They are hard to cut and polish. But oh baby, when they are polished expertly, the result is dramatic . .   . .  highly polished facets and razor sharp facet junctions. The larger the stones, the better to see it my dear.

Take the splendid Spirit of De Grisogono for example. This is the world's largest cut black diamond, and the 5th largest diamond of any kind whatsoever. It was found as a hefty 587 carat rough crystal. Today, it's slimmed down nicely to a 312.24 carat beauty and set in the diamond encrusted ring you see here. The value for such a wonderful object? Who knows? It seems to have been sold to a private customer who's keeping that all under wraps.
