Are Lab Grown Gemstones Real Gems?

Absolutely! Our lab-grown gems, including rubies, sapphires, emeralds, and alexandrites, are 100% real. They are chemically, physically, and optically identical to earth-mined stones but cost up to 90% less.

How Are Lab Grown Gems Created?

A popular method for creating lab-grown gemstones is Flux Fusion. Over six to twelve months, crystals grow in a controlled environment that mimics natural conditions. This process involves the careful application of minerals, heat, and pressure, ensuring the gradual formation of high-quality gems. By replicating the natural environment, Flux Fusion produces gems with the same physical and chemical properties as their natural counterparts. This method provides an ethical, sustainable, and equally brilliant alternative to mined gemstones, catering to the discerning tastes of modern consumers.
