🌍 GENERAL MATERIAL DESCRIPTION

  • Material Name:CZ Alex
  • Country of Origin : Thailand
  • Growth Method: Czochralski

Lab-grown Alexandrite, meticulously cultivated through the Czochralski method by Tairus in Thailand, is a sophisticated response to the increasing demand for precious gemstones. This innovative process yields a trichroic mineral, remarkable for its ability to display a spectrum of colors — green, blue, and a hint of orangish hues — depending on the crystallographic axis along which it is viewed and cut. This unique characteristic means that the specific orientation chosen for cutting can subtly influence the final appearance of the gem, making each piece distinct with its color transitions.

However, the inherent darkness of this lab-created material presents a limitation on the size of the finished gemstone. In addition to its fascinating color shift, this synthetic Alexandrite showcases an extraordinary red fluorescence when exposed to sunlight, similar to the deep red seen in Christmas garnet. This intense fluorescence adds another layer of beauty, making the gemstone glow with a captivating red hue under direct sunlight. Such a feature not only enhances its visual appeal but also sets it apart from other gemstones, making it a prized possession for collectors and jewelry enthusiasts alike.

By combining the traditional allure of natural Alexandrite with the advancements in synthetic gemstone production, Tairus's lab-grown Alexandrite bridges the gap between rarity and accessibility. It offers a sustainable and beautiful alternative that captures the essence of one of the most sought-after gemstones in the world, ensuring that each piece can be cherished for its unique beauty and remarkable properties.

🏭 SPECIFIC Lot INFORMATION

This specific material, notable for its deep hue, is best used for stones smaller than 15mm. Capturing its essence in photographs poses a challenge due to its intense darkness. However, it dazzles with beautiful, color-changing sparkles. Admirers of darker, color-shifting gems such as natural alexandrite or garnet will find this material particularly appealing.
