Sharp square brilliant facets deliver intense concentrated sparkle with clean geometric lines. Multiple fancy shades available, we offer loose gems, finished jewelry and full bespoke customization.
Princess cut lab grown diamonds feature a symmetrical square shape with pointed corners and dense brilliant faceting, creating bold concentrated sparkle distinct from soft oval, romantic heart and linear emerald styles. Crafted with HPHT and CVD technology, they come in white, golden yellow, pastel pink and vivid blue fancy colors to suit modern and vintage bridal aesthetics.
Precise angular facets maximize light return for striking shine, while polished smooth side edges minimize skin friction for comfortable daily wear. Its neat square outline brings a sleek, sophisticated vibe, perfectly suited for contemporary engagement rings, square stud earrings and minimalist pendants.


We stock full-size loose princess lab diamonds, complete matching jewelry sets and one-stop personalized custom services. Ideal for customers who love neat architectural silhouettes, these stones are widely used for proposal gifts, wedding bridal sets and exclusive customized luxury fine jewelry collections.
