Engagement Rings
Lab Grown Ruby
Our PUREGEM® rubies are grown to the most prized standard in the ruby world — a vivid, consistent blood red with exceptional fire and brilliance. With a hardness of 9 Mohs, ruby is second only to diamond and an outstanding choice for engagement rings and fine jewellery worn daily.
Every PUREGEM® ruby is hand-selected for superior clarity, available in any cut and size, and priced 70 to 90 percent less than a comparable natural ruby.
Lab Grown Emerald
Emeralds have symbolized love, rebirth, and wisdom for centuries — and the finest are among the rarest coloured stones in the world. PUREGEM® emeralds capture the rich, lush green of the world's finest Colombian and Zambian stones, without the inclusions, treatments, or environmental cost of mining.
Unlike most natural emeralds which require oiling or filling to mask inclusions, every PUREGEM® emerald is grown to VVS to FL clarity — a standard that natural emeralds at any price rarely achieve. Available in two colour profiles: Colombian Light Green for a vivid, bright tone and Zambian Dark Green for a deeper, richer hue.
Lab Grown Blue Sapphire
The most iconic coloured stone in fine jewellery — deep, velvety royal blue with exceptional clarity and brilliance. PUREGEM® blue sapphires evoke the legendary Kashmir and Ceylon stones prized by collectors worldwide, grown conflict-free at a fraction of the natural equivalent. Hardness: 9 Mohs.
Lab Grown Pink Sapphire
Soft, romantic, and increasingly sought-after as a distinctive alternative to pink diamond. PUREGEM® pink sapphires range from delicate blush to vibrant deep pink — each one grown to exceptional clarity with the same 9 Mohs hardness that makes sapphire one of the finest choices for engagement rings and everyday fine jewellery.
Lab Grown Yellow Sapphire
Warm, luminous, and strikingly beautiful against yellow gold and rose gold settings. PUREGEM® yellow sapphires offer vivid, consistent colour that rivals the finest natural stones — grown to exceptional clarity with the same 9 Mohs hardness as all corundum gemstones. A vibrant and meaningful alternative to yellow diamond at a fraction of the cost.
All PUREGEM® sapphires are available in a wide range of cuts and sizes, ready to be set into your custom design.
What Are Lab Grown Gemstones?
Lab grown gemstones are real gemstones — not imitations, not simulants. They are chemically, physically, and optically identical to rubies, sapphires, and emeralds formed deep within the earth. The only difference is their origin.
Natural gemstones take millions of years to form under extreme heat and pressure. PUREGEM® lab-grown gemstones replicate those exact conditions in a controlled environment, producing stones with fewer inclusions, more consistent colour, and a significantly smaller environmental footprint — in a fraction of the time.
The result is exceptional quality you can see, at a price that makes sense.environmental impact.
How Are Lab-Grown Rubies, Sapphires & Emeralds Made?
At Quorri, we use the most advanced and ethical methods to grow our PUREGEM® lab-grown gemstones:
Ruby & Sapphire (Corundum): We primarily use the flame-fusion (Verneuil) process, where pure aluminum oxide powder is melted at extremely high temperatures and slowly crystallized. This method produces the famous “pigeon’s blood” red rubies and vibrant blue, pink, and yellow sapphires with exceptional clarity.
Emerald (Beryl): Our lab-grown emeralds are created using the hydrothermal or flux-growth method, which closely mimics the natural formation process. The result is rich, saturated green emeralds that rival the finest Colombian and Zambian stones in color and brilliance.
Every PUREGEM® stone is meticulously inspected to ensure it meets our strict standards for color, clarity, and cut before it reaches you.
Lab Grown Sapphire Gemstones
Sapphires are the birthstone of September and one of the most popular choices for engagement rings. Our lab-grown sapphires offer the same legendary durability (Mohs 9) and stunning color as natural sapphires — without the premium price tag.
