Just took a look at Christie’s eCatalogue for their New York Jewels Sale in October. There are a lot of outstanding pieces of jewelry in the upcoming sale–like the Bvlgari Blue, some amazing JAR pieces, many huge diamond rings, and the Vanderbilt diamond necklace. The impeccable diamond necklace (above) features detachable pear-shaped diamonds, all set in platinum. Below is the JAR violet ring crafted in pink sapphire. Below that is a cat’s eye chrysoberyl ring designed by Oscar Heyman and Brothers mounted in 18k yellow gold and platinum. And the Bvlgari Blue, one of the rarest blue diamonds to date (vivid blue), is set to be sold at Christie’s. The ring is projected to go for $15 million! Take a look at some of the highlights from the catalogue, and if you are enticed check out the entire 400 page spread.
