Lab-Grown Gemstones: Emerald, Paraiba, Padparadscha & More

Coloured gemstones are priced by the rarity of their colour. Growing them in a lab removes that rarity premium while keeping the colour — and the inclusions that weaken natural stones.

Emerald

Colombian colour is brighter with a slight blue cast; Zambian is deeper and cooler. Lab-grown emerald has the characteristic green without the surface-reaching fractures that make natural emerald risky in a daily-wear ring.

Paraiba

The neon blue-green of paraiba tourmaline is one of the most distinctive colours in jewelry, and one of the most expensive naturally. Lab-grown makes it accessible.

Padparadscha

The pink-orange 'lotus blossom' sapphire. Rare and warm, it flatters yellow and rose gold particularly well.

Sapphire and ruby

Both are corundum, 9 on the Mohs scale, and both are hard enough for everyday rings. Lab-grown gives you even saturation and eye-clean clarity.

Which to choose for which piece

Emerald and padparadscha look best with protection — pendants, earrings, or a bezel-set ring. Sapphire, ruby and paraiba are tough enough for any setting. Browse lab-grown gemstone jewelry.
