🌍 GENERAL MATERIAL DESCRIPTION

  • Material Name:CZ Yellow Sapphire
  • Country of Origin : China
  • Growth Method:

Yellow Czochralski sapphire is a beautifully crafted synthetic gemstone, created using the sophisticated Czochralski process. This innovative method of crystal growth involves melting a nutrient-rich material in a crucible, then carefully introducing a seed crystal into the molten mix and gradually withdrawing it. This delicate process allows the crystal to develop meticulously on the seed, resulting in a single, flawless crystal.<br><br>The captivating yellow hue of this sapphire is the result of trace impurities embedded within its crystal structure, with iron being the predominant element that imparts the yellow coloration. However, additional dopants can also contribute to this effect. When iron atoms integrate into the crystal lattice of corundum (the base mineral of sapphire), they selectively absorb certain wavelengths of visible light. This absorption process enables the distinctive yellow color to emerge, captivating the human eye. The intensity and specific tone of yellow can fluctuate based on the iron concentration and the presence of other trace elements, which can influence both color saturation and hue. The precise chromophore responsible for the yellow coloration in this material has not been conclusively identified through testing.

🏭 SPECIFIC Lot INFORMATION

Yellow Czochralski sapphire is a rare material with limited industrial applications that justify its high production costs. The primary investment in creating this material was driven by the desire to manufacture entirely sapphire yellow watch cases, a niche but high-value endeavor. The unique appeal and premium nature of full sapphire yellow watch cases provided the financial incentive for developing this specialized material, despite its otherwise limited industrial use.
