An Elegant Twist. This six prong solitaire engagement ring features a round brilliant cut diamond, the most popular shape. You control the price by selecting the 4 C's: carat weight, cut, color and clarity. The classic six prongs come with a twist. To understand, take a look from the side view. The prongs are formed by six arms that gracefully embrace the diamond, a woven basket. Simply beautiful. Available in platinum of 3 colors of 18, 14 and 10k gold: yellow gold, white gold or pink gold. Engraving available.
