An important diamond rivière necklace

An important diamond rivière necklace comprising a graduated line of fifty-one round brilliant-cut diamonds, weighing 7.19, 5.06, 5.00, 3.41, 3.40, 3.27, 3.25, 3.16, 3.12, 2.35, 2.27, 2.21, 2.02, 2.00, 1.70,1.65, 1.40, 1.30, 1.29, 1.28, 1.25, 1.12, 1.06, 1.02, 0.80, 0.75, 0.75, 0.75, 0.72, 0.72, 0.71, 0.70, 0.70, 0.70, 0.70, 0.64, 0.61, 0.61, 0.60, 0.58, 0.57, 0.57, 0.55, 0.54, 0.53, 0.52, 0.52, 0.52, 0.38, 0.34 and 0.31 carat, joined by a heart-shaped clasp, weighing 2.04 carats

The 130 lots are led by an important diamond rivière necklace estimated at $1,400,000-1,800,000. The jaw-dropping jewel is composed of 52 graduated round brilliant-cut diamonds weighing more than 70 carats in total. What’s more, the diamonds are of the highest graded cut, polish and symmetry grade, rendering them Triple X-cut diamonds. Pulling the sparkling rivière together is a heart-shaped diamond clasp.

While colorless diamonds remain a constant, it is the colored gemstone that is making waves this year in both new jewelry and old. Prices for vibrantly colored diamonds, spinels, tourmalines and the like have risen noticeably over the past year and this sale offers an exciting mix of richly hued diamonds and gemstones.

For pink diamond lovers, the sale boasts a blushing stunner – a 3.56-carat Fancy Intense pink diamond and diamond ring estimated at $600,000-800,000. If blue is more your speed, there is a shining star of a ring centering a 0.71-carat Fancy Deep blue diamond in a diamond-studded star setting. That stellar jewel is estimated to fetch $250,000 to $350,000. Trouble choosing a color? Then, a floral motif crossover ring by William Goldberg is set with diamonds of many colors, including a Fancy Dark greenish-gray diamond and a Fancy brown-pink diamond (est. $50,000-70,000).
