Frequently Asked Questions +
Are lab grown diamonds real diamonds? +
Yes. Lab grown diamonds are 100% real diamonds with the same chemical structure, hardness, brilliance, and fire as mined diamonds. They are made of pure crystalline carbon and are graded by the same international standards as natural diamonds.
How are lab grown diamonds made? +
Lab grown diamonds are created using advanced CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature) technology. These processes replicate the natural conditions under which diamonds form deep within the earth, but in a controlled laboratory environment.
Do lab grown diamonds look different from mined diamonds? +
To the naked eye, lab grown and mined diamonds look the same in terms of brilliance, sparkle, and clarity. Even trained gemologists rely on advanced instruments and laser inscriptions on the girdle, not eyesight alone, to tell them apart.
Are lab grown diamonds durable enough for everyday wear? +
Yes. Lab grown diamonds have a hardness rating of 10 on the Mohs scale, just like natural diamonds. They are highly durable, scratch-resistant, and suitable for everyday jewellery such as engagement rings, wedding bands, earrings, bracelets, and pendants.
Why do people choose lab grown diamonds instead of mined diamonds? +
Many people choose lab grown diamonds for better value, transparent and traceable sourcing, lower environmental impact, and the ability to pick larger or higher quality stones within the same budget compared to mined diamonds.
Are lab grown diamonds environmentally friendly and ethical? +
Lab grown diamonds avoid traditional mining and generally use fewer natural resources and less land disruption. For many modern buyers, this makes them a more sustainable and ethical choice with a smaller environmental footprint.
Are lab grown diamonds certified by IGI, GIA, and other labs? +
Yes. Lab grown diamonds are certified by the same trusted gemological laboratories that grade natural diamonds, including IGI and GIA. Each certified stone comes with a grading report detailing its 4Cs (cut, colour, clarity, carat), proportions, and growth method.
Do lab grown diamonds have resale value? +
Like most jewellery, resale value depends on demand, quality, and market conditions. Lab grown diamonds focus on delivering strong upfront value by offering more size and quality for your budget, which is why many people prioritise their beauty and wearability over potential resale.
Can lab grown diamonds be used in any type of fine jewellery setting? +
Absolutely. Lab grown diamonds can be set in all types of fine jewellery, just like mined diamonds. They work perfectly in 18K gold, platinum, and other precious metals across engagement rings, wedding bands, earrings, necklaces, bracelets, and custom designs.
Do lab grown diamonds come in different shapes, sizes, and qualities? +
Yes. Lab grown diamonds are available in all popular shapes—round, oval, emerald, cushion, radiant, pear, marquise, princess, heart, hexagon, and more—across a wide range of carat weights, colours, and clarity grades, just like mined diamonds.
