Vintage 10k Gold Three-Stone Ring with Square Blue Sapphire and CZ Accents

A refined statement of colour and craftsmanship, this vintage 10k gold ring showcases a beautifully cut square blue sapphire framed by two brilliant round CZ stones. The sapphire tests as corundum on the Presidium tester and displays the saturated cobalt tone associated with high-quality lab sapphires—clean, vibrant, and full of light.

The three-stone arrangement is elevated by the sleek architectural lines of the gold setting, giving the ring an elegant profile with a contemporary edge. Each stone is held securely in a sculpted open-back gallery designed to maximize brilliance and colour play.

This is a ring that feels luxurious on the hand: substantial, visually balanced, and crafted with attention to detail. Whether worn as a right-hand statement piece or as a treasured addition to a fine jewellery collection, it delivers sophistication and presence in equal measure.
