Kay Jewelers Review 2026: Lab-Grown Diamonds
Kay Jewelers
Best Colored Lab DiamondsLast Updated: April 2, 2026
Kay Jewelers is a strong choice for buyers seeking designer lab-grown diamond collections — especially colored lab diamonds. Their Monique Lhuillier Bliss collection (pink, blue, yellow lab diamonds) is unique in the industry. Prices are higher than online-only specialists but competitive for a physical retailer with designer partnerships. Best for buyers who want something distinctive rather than a standard white diamond solitaire.

Quick Answer
Is Kay Jewelers a good place to buy lab-grown diamonds?
Yes — particularly if you want colored lab diamonds, designer collections, or in-store service. Kay's Monique Lhuillier Bliss collection with pink, blue, and yellow lab diamonds is unique among major retailers. For standard white lab diamonds at the best price, online-only retailers like James Allen or Clean Origin will be cheaper.
📊 Kay Jewelers is one of the only major retailers offering pink, blue, and yellow lab-grown diamond engagement rings through their Monique Lhuillier Bliss collection.
Our Experience Testing Kay Jewelers
We tested Kay Jewelers both in-store and online. The in-store experience was warm and helpful — staff were knowledgeable about their lab-grown offerings and proactively highlighted the Lab-Created Diamonds by KAY collection. Online, Kay's website is functional with reasonable filtering, though not as advanced as James Allen's or Brilliant Earth's search tools.
The standout discovery was the Monique Lhuillier Bliss collection — genuinely beautiful colored lab diamond rings we haven't seen at other major retailers. If a colored engagement stone appeals to you, Kay is the leading destination.
