Whiteflash

Whiteflash is an online seller based in Sugar Land, Texas, that specialises in GIA-certified natural diamonds and also offers IGI-certified lab-grown stones. Its A CUT ABOVE line is a super-ideal round cut with hearts-and-arrows precision, and natural GIA diamonds carry AGS Ideal reports as well. The lab-grown side runs under a Precision Lab Diamond brand. Loose stones come in the usual range of shapes, and finished engagement rings, wedding rings and jewellery are available alongside designer collections.

Each stone is shown with HD video and can be examined through diamond analytics tools such as ASET, Ideal Scope and the HCA, and the education section covers the four Cs. Free worldwide shipping, a lifetime trade-up program and a money-back guarantee mean a Zurich buyer can pick the diamond first and ship it in for setting.
