Cornflower Blue Cushion Sapphire

This is a classic Ceylon sapphire — unheated Sri Lanka stone with that clear, cornflower blue you see in the trade. In daylight it reads a bright, clean medium blue; under warm incandescent light it takes on a slightly richer, warmer tone and shows moderate pleochroism if you tilt it. Eye-clean clarity means there are no visible inclusions to the naked eye, so the face-up is open and lively; you won’t need a halo to mask anything. The cushion cut balances brilliant facet play on the crown with a solid pavilion — gives good scintillation without sacrificing depth. For durability, I recommend a four or six-prong head with slightly raised gallery or a low-profile bezel if the piece will be worn daily. Metal pairing: platinum or 18k white gold keeps that pure blue crisp; 18k yellow or rose will warm the stone if you want a softer look. Best uses: engagement ring or a pared-back pendant where the colour is the star, or a signature cocktail ring with protective shoulders. Practical, wearable, and straightforward to set well.
