Blue Sapphire

About this stone

Blue Sapphire is a corundum that medieval clergy wore to vow celibacy and that Vedic astrologers reach for to ground a chaotic Saturn. In Western practice it is a Saturn-and-Jupiter stone: structural clarity that does not collapse into pessimism. It is potent — Vedic tradition cautions trying it on for a few days first — and best for charts where hard aspects keep cycling without resolution.
