Many jewellery brands cut corners to reduce cost - for example, using lighter, thinner settings, less gold, or simplified constructions.

At Atlas Carré, we don’t compromise: our pieces are built solid, with proper weight and durability, advanced innovations like our non-flip tennis setting, and designed for stacking in 13 signature colours.

The result is jewellery that feels substantial, looks striking, and lasts - without shortcuts.

Lab-grown coloured gemstones let us offer the beauty of rare gems - sapphires, rubies, emeralds, spinels, alexandrites - at a fraction of the cost of their mined equivalents. Natural stones of the same quality can be extremely rare and priced out of reach.

By choosing lab-grown, you get the same chemical and optical properties, with greater consistency, vibrant colour options, and far better accessibility - all without the environmental and ethical impact of mining.

Yes, our lab-grown gemstones are chemically, physically, and optically identical to mined stones. They are real gems, created in laboratories using advanced technology that replicates natural conditions - without the environmental or ethical costs of mining.

We offer a curated selection of high-quality lab-grown gemstones, including:

• Diamonds (colorless and fancy hues)
• Sapphires (blue, pink, yellow, purple, orange)
• Emeralds
• Rubies
• Alexandrites
• Amethysts
• Citrines
• Spinels (blue, green, black)
• Tsavorites (Green garnet - YAG)
• Cultured pearls - saltwater and freshwater.

Lab-grown gemstones (also called synthetic or synthesised) are real gems, with the same chemical composition and crystal structure as natural stones.

Simulated gemstones only imitate the appearance of other gems but have a different composition. For example, we use high-quality spinels to simulate aquamarine, blue topaz, and green tourmaline.

There are two main methods:

• HPHT (High Pressure High Temperature): replicates the natural conditions of heat and pressure.
  
• CVD (Chemical Vapor Deposition): grows diamond layers from carbon-rich gas inside a chamber.
  

Both methods create real diamonds that are chemically and visually identical to mined ones.

Yes. All our lab-grown diamonds above 0.5 ct are certified by the International Gemological Institute (IGI). Certification covers the 4Cs: Cut, Color, Clarity, and Carat weight.

Yes. Upon request and for an additional fee, we can provide third-party gemological certification for colored lab-grown gemstones. This includes rubies, sapphires, emeralds, and other premium stones.

Yes. Like natural gems, lab-grown stones can show inclusions - though usually fewer and less visible thanks to controlled growth. Each stone is unique and hand-selected for exceptional quality.

Yes. Lab-grown gemstones are far more sustainable than mined stones: they require less energy, use minimal water, and avoid destructive mining practices.

Lab-grown gemstones are not typically purchased for investment purposes. Their value lies in their exceptional quality, beauty, and sustainability.

While you may find stones advertised as “lab-grown” on mass-market sites, they are often not genuine lab-grown gemstones but cubic zirconia or other simulants. Even when they are real, lab-grown gems vary widely in quality - just like mined stones.

At Atlas Carré, we use only premium-grade lab-grown gemstones, cut to the highest standards for brilliance and colour. Each stone is carefully selected and set by hand to ensure exceptional beauty and durability. This means our gems are not just affordable alternatives, but true fine jewellery gemstones - designed to last and hold their value.

Because we believe in conscious luxury. Lab-grown stones deliver the same brilliance and beauty as mined gems -without the environmental damage or ethical concerns of mining.
