Asscher Cut Three Stone Engagement Rings in Platinum Under £4,500

A platinum three-stone ring combines the symbolism of past, present, and future with the enduring strength of platinum. Each diamond is held securely by the densest precious metal, ensuring the trilogy remains intact for generations.

The Asscher cut is a square step-cut diamond with deeply cropped corners that create an almost octagonal outline. Its concentric square facets draw the eye deep into the stone, producing a mesmerising windmill pattern. Invented in 1902 by the Asscher Brothers, it remains one of the most distinctive and collectible diamond shapes.
