"The Perfect Palette," a trio of fancy vivid colored diamonds sold in separate lots at Christie’s New York Magnificent Jewels auction, amassed a total of $8.4 million, cumulatively, after their gavels had fallen.
Recently the IGI Lab in Shanghai received an antique Etruscan revival style necklace from the mid to late 19th century. When the necklace was submitted, IGI gemologists immediately understood the reason it was sent for identification: It seemed to weigh less than it should and, therefore, was suspected to be made of gilt copper, rather than gold.
The International Organization for Standardization (ISO), the world's largest developer of voluntary international standards, has certified IGI with the ISO 17025 accreditation for lab-grown diamonds, making IGI's laboratories the world's first to hold ISO accreditation for both natural and lab-grown diamonds.
Natural pink diamonds are extremely rare. When discovered, only one in 10 weighs more than 0.20 carats. This year, as the annual cherry blossom season hits its peak, the 15.81 carat flawless, fancy vivid purple-pink Sakura Diamond will be the star of Christie's Hong Kong’s Magnificent Jewels sale.
IDEX was among the first jewelry industry news outlets to cover IGI's unprecedented partnership with Diamond Standard, an entity which has received regulatory approval to offer the world's only market traded diamond commodity - the Diamond Standard Coin.
