A breathtaking mine of diamonds awaits collectors at Christie’s Hong Kong. The auction house’s June 2 Hong Kong Magnificent Jewels sale features an astounding thirteen diamond rings valued at over $1 million each. Spellbinding in shades of pink, green, blue, and orangy yellow, the spectacular, sizable rocks have their beauty enhanced by a variety of expert cuts and settings. But lovers of traditional white bling should take note of Lot 2108. It features an important 15.15-carat, rectangular-shaped Graff diamond. Flanked by tapered baguette-cut diamonds on its platinum mount, the irresistible bauble is waiting to be scooped up for an estimated $1,814,301 to $2,332,672. 

Lot 2105, a ring from discreet jeweler Moussaieff, is a standout with its pear-shaped fancy intense blue diamond surrounded by pink diamonds.
