Shop Gemstone Engagement RingsLab grown gemstones (also known as lab-created, cultured, or synthetic gemstones) are real gemstones that are grown in a laboratory rather than mined from the earth. They are not imitations or simulants — they are chemically, physically, and optically identical to natural rubies, sapphires, and emeralds.
The only difference is their origin. While natural gemstones take millions of years to form deep within the Earth under extreme heat and pressure, lab-grown gemstones are created in controlled environments that replicate these exact conditions in just a few weeks or months.
This modern approach allows us to produce exceptional quality gemstones with fewer inclusions, more consistent color, and significantly lower environmental impact.
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.
Choosing the perfect lab‑grown gemstone is simple when you follow these expert steps:

Our lab grown rubies are renowned for their intense “pigeon’s blood” red color — the most sought-after hue in the world. With Mohs hardness of 9, they are incredibly durable and perfect for everyday wear in engagement rings and fine jewelry.
Key Features of Quorri Lab Grown Rubies:
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.
The classic royal blue sapphire remains the most popular choice. Our lab-grown blue sapphires display rich, velvety color with outstanding clarity and brilliance.
Romantic and feminine, our lab-grown pink sapphires range from delicate pastel to vibrant hot pink. Perfect for unique engagement rings and meaningful gifts.
Sunny and cheerful, yellow sapphires bring warmth and positivity. Our lab-grown versions offer intense, even color that rivals the finest natural stones.
All of our lab-grown sapphires are available in a wide range of shapes and sizes, ready to be set into your dream jewelry design.
Emeralds are the birthstone of May and have symbolized love, rebirth, and wisdom for centuries. Our lab-grown emeralds capture the rich, lush green color of the world’s finest natural emeralds while offering superior clarity and durability.
Unlike many natural emeralds that require oiling or other treatments to hide inclusions, our lab-grown emeralds are naturally inclusion-free or have only the most minor inclusions — giving you a cleaner, more brilliant stone at a much more accessible price.
