Bulk Asscher HPHT CVD Lab Diamonds & Fine Jewelry
Square clipped-corner step-cut stones deliver iconic hall-of-mirrors depth, supplied in full fancy hues. We offer bare gems, finished jewelry and bespoke customization for vintage bridal & luxury collections.
Asscher cut lab grown diamonds feature a unique square silhouette with four cropped corners and orderly concentric step facets, generating a stunning hall-of-mirrors optical depth that differs sharply from pear cut’s elongated teardrop sparkle. Produced via mature HPHT and CVD technology, they cover white, yellow, pink and blue fancy colors to match diverse vintage Art Deco styling demands.
The clipped corners eliminate fragile sharp tips, boosting durability for daily wear without easy chipping. Geometric symmetrical lines create a poised, sophisticated wearing effect, ideal for vintage engagement rings, square stud earrings and geometric pendants.
We supply full-size loose Asscher lab diamonds, finished matching jewelry sets and one-stop personalized custom services. Favored by clients chasing retro architectural aesthetics, these stones stand out as exclusive alternatives to mainstream brilliant and pear-cut gems for high-end bespoke fine jewelry creation.
