Why Buy Blue Gemstones from GemSelect?

FAQs

Do you provide certification for Gemstones in Blue?

Yes. You can add an optional lab report (e.g., ICA GemLab, AIG GemLab, BGL) from the product page before checkout.

How can I find a matching pair for earrings?

Filter by “Pairs” or contact us with your target size, shape, and budget. We can hand-match two stones in the same hue and cut.

What types of Blue Gems do you sell?

We stock Sapphire, Topaz (London/Swiss), Aquamarine, Tanzanite, Spinel, Kyanite, Zircon, Apatite, Lapis, and more. Each listing is a single, unique stone unless noted as a pair or lot.

Are the photos of the exact stone I’ll receive?

Yes. Each listing shows the actual Gemstone - no stock images. Dimensions, weight, and color are measured for that item.
