PHILADELPHIA, PA.- Freeman’s May 17 Jewelry Auction is sure to dazzle and delight jewelry enthusiasts and collectors alike. The nearly 160 lot sale includes a fine selection of antique and contemporary jewelry by names such as Cartier, Tiffany and Co., Van Cleef & Arpels, and Bulgari. 

Interested buyers will have the chance to bid on diamonds of all colors, including blue, pink, and yellow. The most common diamonds contain small amounts of the impurity nitrogen, which causes a diamond to impart a yellow color. The cause of blue in a diamond is due to the presence of the impurity boron. As the amount of nitrogen or boron increases, so will the depth and intensity of color. The star of the show will no doubt be a fancy light yellow diamond, diamond and eighteen karat gold ring ($140,000-180,000) weighing 13.16 carats, flanked by triangular-cut diamonds, and mounted in 18 karat gold, this breathtaking ring is sure to inspire interest from around the globe.

Another unique characteristic is if a chameleon diamond is saturated with fluorescent light, it can phosphoresce for up to one hour.
