HPHT CVD Emerald Cut Lab Grown Diamonds & Rings
Rectangular clipped-corner emerald cut delivers clear mirror-like light stripes, offered in various fancy shades. We provide loose gems, finished jewelry and all-around bespoke customization support.
Emerald cut lab grown diamonds feature a neat rectangular outline with truncated four corners and parallel step facets, forming unique layered mirror light streaks totally different from cushion’s soft glow and pear’s elongated sparkle. Produced by HPHT and CVD techniques, they cover white, golden yellow, tender pink and icy blue color options to meet minimalist and retro Art Deco styling needs.
Flat, low-profile facets and smooth chamfered corners prevent scratches and snags, bringing lightweight, unobtrusive wearing comfort for long daily use. The horizontal rectangular shape visually stretches fingers and necks, ideal for sleek engagement rings, linear drop earrings and minimalist pendants.
We supply full-size loose emerald lab diamonds, complete matching jewelry sets and one-stop personalized custom services. Favored by lovers of understated architectural elegance, these stones are widely used for bridal proposals, formal cocktail ornaments and exclusive customized fine jewelry collections.
