Color Characteristics & Optical Behavior
Soft rose pink, peach, and salmon-pink hues caused by trace manganese; often forms flat tabular hexagonal crystals.
Geological Context & Pakistani / Global Localities
Forms in lithium- and cesium-enriched granitic pegmatites in Pakistan (Skardu/Shigar), Afghanistan (Nuristan), Brazil, and Madagascar.
Collector Interest & Rarity Factors
Tabular pink crystals from the Hindu Kush and Karakoram mountains are prized by crystal collectors for their sharp geometry and association with tourmaline and cleavelandite.
Fine Jewelry Applications
Highly favored for rose-gold engagement rings, cushion-cut pendants, and statement earrings.
Treatment Considerations & Disclosure
Frequently heat-treated at low temperatures or irradiated/annealed to convert yellow/orange modifiers into pure pink. Treatment status is disclosed per specimen.
Care & Cleaning Instructions
Wash gently in warm soapy water; store away from sustained intense heat.
