Pink sapphire price: what it is worth per carat
Pink sapphire spans delicate pink to vivid hot pink. Saturation drives value, and the boundary where intense pink becomes "ruby" is itself a major price threshold.
What drives pink sapphire price
Pink sapphire is corundum in pink hues. Saturation is the main driver: vivid, hot-pink stones are far more valuable than pale ones. Where colour becomes deep enough to be called ruby, value can jump — the pink/ruby boundary is a genuine pricing threshold and can be contentious.
Colour & treatment
Vivid pink to slightly purplish-pink with strong saturation is most prized. Most pink sapphire is heated (standard); unheated stones with lab reports carry a premium. Some hot-pink stones overlap with fancy pink and padparadscha territory.
Clarity, origin & size
Type II corundum tolerates minor inclusions; eye-clean is preferred. Sri Lanka, Madagascar and East Africa are key sources. Fine stones rise in per-carat price with size.
