Its high purity and uniform crystal structure yield exceptional clarity and brilliance, resembling natural sapphire. Ideal for creating stunning gemstones, it offers durability, scratch resistance, and vibrant color, making it a prized material in the world of jewelry design.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eWhile the TGT method is similar to Czochralski, the TGT method relies on a controlled temperature gradient within the crucible, while the Czochralski method focuses on the controlled solidification of a molten melt.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eWith the dichroic nature of sapphire the shade of the stone may be different through each of the axis.
