Purple Amethyst

Purple Amethyst Untreated Fancy Rectangle 5.89CT 11.1x10.1mm 

Untreated purple amethyst is a natural, unheated quartz that gets its signature color from iron impurities and natural irradiation. Unlike heat-treated varieties (which turn yellow-orange into citrine) or irradiated stones, untreated amethysts retain their genuine, often richly varied purple hues. 

Key Characteristics & Value

• Color: Ranging from light pastel "Rose de France" to deep, royal violet or dark purple.
• Pricing: Generally retails between $80 and $180 per carat depending on the color depth, clarity, and cut.
• Testing: Untreated stones are heavily favored by collectors and crystal healers. GIA and IGI laboratory reports are usually required to officially certify a stone as "unheated" or "untreated". 

Sourcing & Uses
