    PureGem® lab-grown emeralds are physically and optically identical to mined emeralds — the same beryl crystal structure, the same 7.5 to 8 Mohs hardness, and the same vivid green colour that has made fine emerald one of the world's most coveted gemstones for centuries.

    Fine-quality emeralds of significant size are among the rarest and most valuable coloured stones in existence. Every PureGem® emerald is individually selected to meet or exceed the highest gem standards — available in two distinct colour profiles: Colombian Light Green for a bright, vivid tone, and Zambian Dark Green for a deeper, richer hue. Compare at $2,000 to $11,000+ per carat for a vivid green natural emerald equivalent.

    Conflict-free, sustainably created, and available at a fraction of the cost of a mined stone. PureGem® lab-grown emeralds are made to order in your choice of cut, shape, and carat size. See the Shipping & Delivery tab for completion estimates, or email us for available in-stock sizes.

     

    About This Stone

    Every PureGem® emerald shares the same chemical composition, crystal structure, and optical properties as a mined emerald — the only difference is how it was created. Grown in a controlled laboratory environment, each stone tests positive as genuine emerald on all standard gemological instruments and meets the same quality criteria as the world's finest natural emeralds.

    Colour
    Available in two versions — Colombian Light Green, a vivid and bright tone favoured for its clarity of colour, and Zambian Dark Green, a deeper and more saturated hue prized for its intensity. Both are consistent, vibrant, and free of the colour variation that makes high-quality natural emeralds so rare.

    Clarity
    VVS to FL. Natural emeralds at this clarity grade are extraordinarily rare and command some of the highest prices in the coloured stone market. Every PureGem® emerald is held to this standard as a baseline.

    Hardness
    7.5 to 8 Mohs — durable for rings, pendants, earrings, and any fine jewellery piece intended for regular wear with proper care.

    Customization
    Available in any cut — emerald, round, oval, cushion, pear, marquise, and more — and in any carat size up to 30 carats. Each stone is hand-cut to your exact specifications and set in your choice of solid 10k, 14k, or 18k gold in yellow, white, or rose, or 950 platinum.

    Ethical & Eco-Friendly
    No mining, no land disruption, no conflict. PureGem® emeralds are sustainably created and conflict-free by design — the same beauty, none of the compromise.
