Fancy Colored Diamonds

You may or may not know that diamonds come in all of the colors of the rainbow, from reds and pinks to blues, greens and yellows. However, not all fancy colored diamonds get their color naturally. Below is an article explaining the color enhancement processes of natural diamonds.

COLOR ENHANCEMENT OF NATURAL DIAMONDS
TREATMENT OF DIAMONDS TO CHANGE THEIR COLOR HAS BEEN AROUND SINCE 1940’S. INITIALLY IT WAS DONE BY EXPOSING THEM TO RADIATION FOLLOWED BY HEAT TREATMENT (ANNEALING). THIS PROCESS IS SIMILAR TO SANITIZING FOOD PRODUCTS. THE RESULTING DIAMONDS ARE FREE OF RADIATION AND SAFE TO USE. THIS TREATMENT PRODUCES COLORS OF BLUE, YELLOW, GREEN, AND VERY RARELY PINKS AND REDS. WHILE THESE COLORS ARE PERMANENT, INDUSTRY TEST SUGGEST CAUTION BE USED FOR EXPOSURE TO TEMPERATURE ABOVE 300-400 C.
Since the 1990’s, the color of diamonds has also been altered by HPHT process (High Pressure High Temperature). Polished or rough diamonds (natural and synthetic) are processed in the lab under very high pressures and temperatures, mimicking conditions deep in the earth where diamonds are formed. Depending on the composition of the diamond the results could be colorless as well as yellow, green, orange, and very rarely pink and blue. Colors produced by HPHT are permanent and they have the same features as a regular natural diamond.
There are other methods of diamond treatment such as PVD (pressurized vapor deposit), a color coating scheme, and clarity enhancements such as lasering, [fracture filling] treating, or filling. Color treatment can be done on any synthetic or [natural/minded] diamond. In the US these processes are done under strict and safe conditions.    Article written by Cendico Diamond

The Wittelsbach diamond, a 35.56-carat fancy deep grayish-blue diamond with a long history, was among the gems slated for auction at Christie’s “Jewels: The London Sale” last month. What was the asking price? Read on:

Officially known as “Der Blaue Wittelsbacher,” the diamond is one of the few that can claim 17th-century heritage.

In 1664, King Philip IV of Spain (1605-1665) selected the diamond as part of the dowry of his daughter, Infanta Margarita Teresa (1651-1673), upon her engagement to Leopold I of Austria (1640-1705), who later became Holy Roman Emperor.

The diamond subsequently became part of the Austrian and then the Bavarian crown jewels.

The diamond has been part of a private collection since 1964, and its appearance at the upcoming Christie’s auction marks its first offering to the international market in nearly 80 years.

“It is a great honor and a lifetime dream to handle a museum-quality stone such as the Wittelsbach,” said Francois Curiel, chairman of Christie’s Europe and international head of jewelry. “The appearance of a large blue diamond, among the rarest of colors, with a history that can be traced back to the 17th century and 300 years of royal connections will surely be a thrilling occasion for all collectors of exceedingly rare jewels and works of art.”

So what did the historic diamond go for? How about a record-setting $24.3 million! Recession? What recession?

“In the midst of these challenging times, we were thrilled to achieve an historic price for an historic diamond,” said Francois Curiel, chairman of Christie’s Europe and auctioneer for Wednesday’s sale.

The previous sales record was a mere $16.5 million for a 100-carat diamond in 1995.

Woo hoo! It’s time to put the conservative, recession-era mindset in a box for a night. No talk about wise, understated jewelry choices. No sir. It’s New Year’s Eve. It’s time for lavishness. Outlandishness. EXCESS!

This New Year’s Eve, pull out that piece that seems a little too much and wear it, proudly. Trust me, this mentality only works for December 31. So why not overdo it this year?

Pull out the stops, baby!
