A $10,000 Valentine Day’s Diamond Proposal

Luxist reports that The Algonquin Hotel in New York City is now offering the most expensive martini ever.

The Grey Goose $10,000 proposal cocktail comes with a one-of-a-kind diamond ring placed in the glass. This specialty cocktail is served by a white gloved waiter in a crystal glass on a silver platter in the hotel’s famous Blue Bar. The hotel arranges for clients to work with a private jeweler to customize the engagement ring by picking carat size, number of stones and the setting. The hotel needs at least 72 hours notice to set up this arrangement.

Guys, don’t forget or slur your proposal speech.

Where is The World’s Second Largest Diamond Market?

Reuters reports today that due to its excellent economic growth which increased by 8.7%, China has overtaken Japan to become the world’s second largest diamond market behind the United States with trade on the Shanghai diamond exchange rising 16.4 per cent to more than US$1.5 billion.

China’s increasingly affluent middle class and vast pool of customers are the key factors for the rise in diamond sales in the world’s most populous country.

Demand for diamonds only really started to develop in the 1990s when De Beers brought its global advertising campaign to China, tapping into the Chinese desire for conspicuous consumption and pursuit of Western lifestyle trends.

Engagement Rings Online

Here are some pictures of a recent diamond engagement ring we completed for one of our customers! This is a very popular classic solitaire engagement ring and we have sold many of them right here in the New York City Diamond District. I don’t know if there are specific engagement rings that New Yorkers are buying, but I do know that the ratio of these engagement rings sold to New Yorkers, is quite impressive!

Take a look.

Diamond Engagement Rings On Neptune and Uranus?

Not so far-fetched.

The journal, Nature Physics in a recent article reports that oceans of liquid diamond, filled with solid diamond icebergs, could be floating on Neptune and Uranus.

This research is based on first detailed measurements of the melting point of diamond and found that diamond behaves like water during freezing and melting, with solid forms floating atop liquid forms. The finding gives scientists a new understanding about diamonds and some of the most distant planets in our solar system.

Diamond is an incredibly hard material, tough to melt and thus its difficult to measure its melting point. When diamond is heated to extreme temperatures it physically changes from diamond to graphite. The graphite then melts into a liquid.

Ultrahigh pressures such as found in huge gas giants like Neptune and Uranus are some of the places where ultrahigh temperatures and ultrahigh pressures exist. In this study, scientists liquefied a small diamond weighing a tenth of a carat at by blasting it with lasers at ultra high pressures 40 million times greater than what a person feels when standing at sea level on Earth. From there they slowly reduced the temperature and pressure.

When the pressure dropped to about 11 million times the atmospheric pressure at sea level on Earth and the temperature dropped to about 50,000 degrees solid chunks of diamond began to appear. The pressure kept dropping, but the temperature of the diamond remained the same, with more and more chunks of diamond forming. Then the diamond did something unexpected. The chunks of diamond didn’t sink. They floated. Microscopic diamond ice burgs floating in a tiny sea of liquid diamond. The diamond was behaving like water.

With most materials, the solid state is more dense than the liquid state. Water is an exception to that rule; when water freezes, the resulting ice is actually less dense than the surrounding water, which is why the ice floats and fish can survive a Minnesota winter.

Up to 10 percent of Uranus and Neptune is estimated to be made from carbon.

Have You Ever Seen A Red Diamond?

They really exist, but are very rare.


Leibish & Co .52 Carat Natural Purplish Red Argyle Diamond

You’re looking at the .52 carat, SI-1 Clarity Radiant shape Argyle Natural Purplish Red Diamond, mined from the Argyle Diamond mine in Western Australia and now owned by the Israeli Diamond Wholesaler, Leibish & Co. The diamond was grade by the GIA Gem Trade Laboratory. The majority of the current red diamonds weigh less than one-half carat. The Argyle Mine accounts for 95% of all the red and pink diamonds in the world and supply is expected to run out by 2018.

According to Robert Kane of the GIA Gem Trade Laboratory, intense and vivid pink diamonds are rare and red where the primary dominant hue is purplish red is the rarest of all. Red diamonds are among the rarest of fancy color diamonds with only 20 known natural red diamonds in the world and have sold for record breaking prices.

In 1987, the fancy purplish red .95 carat Hancock Red Diamond sold for $926,000 per carat, and in 2007, a 6.04 carat flawless fancy blue diamond was sold by Sotheby’s Auction House for $1.3 million per carat! Compare this to to the price for the highest colorless and flawless diamond which trades at $100,000 per carat.

In the world of fancy colored diamonds; “Do you see red”, can take on a whole other positive meaning.
