If you live in or are visiting New York City the next few months, you might want to stop by the American Museum of Natural History and get a rare chance to view some exceptional colored diamonds. September 15 was the opening of a new display of in the museum’s Morgan Memorial Hall of Gems.
The collection includes the following diamonds:
- An intense-pink brilliant diamond from the Argyle Diamond Mine in Australia set in gold metal mounting with small pink diamonds designed by Carvin French.
- A 5.4-carat round brilliant-cut diamond set in a white gold pendant with 20 sapphires, designed in California in 1960.
- Five vivid naturally colored diamonds ranging in size from 1.01 to 2.34 carats from the Olympia Diamond Collection, which are on loan from Scarselli Diamonds. The five diamonds are a 1.01-carat vivid orange-yellow diamond (mined in Africa), a 1.02-carat vivid blue-green diamond (mined in Brazil), a 2.17-carat vivid purplish-pink diamond (Argyle Mine in Australia), 2.13-carat vivid blue diamond (mined in Africa), and a 2.34-carat vivid orange diamond (from Africa). The vivid color grade is the highest colored diamond grade given by the GIA (Gemological Institute of America) and these five diamonds are rare because they are completely saturated colors.
- Synthetic (laboratory-grown) diamonds from the Boston-based Apollo Diamond Corporation, created using the chemical vapor deposition (CVD) technique. The display shows the stages of growth of CVD diamonds as the diamonds form in gas mixture to a heated chamber containing “seed” material.
- Synthetic (laboratory-grown) diamonds from Sarasota, Florida-based Gemesis Corporation, created using the high-pressure, high-temperature (HPHT) technique, which uses large presses to transform carbon material to diamond using compression. The display includes uncut and cut (polished) diamonds, loose and in jewelry.
This special colored diamond display runs until January 2010 and is free with admission to the museum, which is located at Central Park West and 79th Street in Manhattan.
