This polycrystalline/ceramic spinel is created using the Hot Isostatic Pressing (HIP) process.  HIP spinel for gemstones is created under intense heat and pressure in an inert gas environment. This process enhances its clarity, color, and durability, making it ideal for crafting high-quality gemstones prized for their beauty and resilience

The faceted gem is for example only, and is not included.
