Colored Lab Diamond Jewelry

Kay lists a designer collection with colored lab-grown diamonds (such as pink, blue and yellow). Colored lab diamonds are less commonly offered by some large online specialists, so this may be of interest if you want something other than a white diamond. Check the retailer's listings for current availability and specifications.

Lab Diamond Selection at Kay Jewelers

Kay publishes a dedicated lab-grown collection covering engagement rings, wedding bands, earrings, necklaces and bracelets, along with designer collections it lists on its site. According to the retailer, lab-grown diamonds come with independent grading reports. Check the report on the specific stone.

The loose lab diamond search is narrower than at online specialists.

Pricing: How to Compare

Kay's prices are often higher than online-only specialists but can be comparable to other store-based jewelers. The retailer runs promotions from time to time, so check its site for current offers.

Compare the same specification (carat, color, clarity, cut, certificate) at James Allen, Brilliant Earth and Clean Origin for your stone.
