Asscher Cut Solitaire Engagement Rings in Platinum Under £2,000

Platinum solitaire is the most refined combination in engagement ring design. The purest precious metal holding a single diamond — nothing more, nothing less. This pairing has defined the engagement ring category for over a century.

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.
