In the fascinating world of gemstones, sapphires are highly cherished for their brilliant hues and unrivaled durability. Traditionally mined from the depths of the Earth, sapphires are now being grown in laboratories with exceptional precision and sustainability. This breakthrough in gemology has been led by pioneers like Djeva, a Swiss factory that has mastered the Verneuil method of synthesizing sapphires. Their innovative approach has enabled us at Niji to offer a rainbow spectrum of 16 different colors of lab-grown sapphires, all sourced just an hour and a half away from home.
The Magic of Lab-Grown Sapphires
Sapphires are the gems of the corundum family, famed for their intense blues. However, sapphires are not confined to the blue spectrum; they are found in an array of colors, including pink, yellow, green, and even white. These 'fancy' colored sapphires are rare in nature, but thanks to modern gemological practices like the Verneuil method, they can now be grown in a lab environment.
Lab-grown sapphires possess the same physical, chemical, and optical properties as their naturally occurring counterparts. This means that aside from their origin, there's essentially no difference between a lab-grown sapphire and a mined one. The real magic lies in the Verneuil process, which has made the production of these stunning gems both affordable and sustainable.
The Unwavering Quality of Lab-Grown Sapphires
While the term "lab-grown" might make one think of replicas or substitutes, in the case of sapphires, nothing could be further from the truth. Lab-grown sapphires are every bit as real and exquisite as sapphires mined from the earth. They are composed of the same mineral - corundum - and share the same hardness, second only to diamond on the Mohs scale. This unparalleled durability means our sapphires can be worn anywhere, standing up to the rigors of daily wear while retaining their stunning brilliance.
This is the key distinction between lab-grown sapphires and other gemstone simulants such as cubic zirconia or Swarovski crystals. While these materials are often used to mimic the appearance of precious gemstones, they do not share the same properties. Cubic zirconia, for instance, ranks much lower on the Mohs scale, making it less resistant to scratches and wear over time. Similarly, Swarovski crystals are a type of glass, lacking the hardness and refractive index that define precious gemstones.
Mastering the Verneuil Method at Djeva
Named after the French chemist Auguste Verneuil, who developed it in the early 20th century, the Verneuil method, also known as flame fusion, is one of the oldest and most cost-effective methods of creating synthetic gemstones. The process involves dropping a mixture of fine aluminum oxide powder (the primary constituent of sapphire) and coloring agents through a high-temperature flame, where it melts and falls onto a boule, solidifying into a cylindrical crystal as it cools.
Swiss factory Djeva has not only mastered this technique, but they have also made significant advancements to create a whole palette of sapphire colors. By carefully adjusting the types and amounts of coloring agents used in the process, Djeva's expertise allows for the creation of sapphires in a range of stunning hues. The fact that these gems are grown in labs doesn't diminish their beauty or value; it enhances it, allowing for greater control over the final product's color, clarity, and size.
