Asscher Cut Halo Engagement Rings in Platinum Under £7,500

A platinum halo setting frames the centre diamond with a ring of smaller stones, all secured in the strongest precious metal. Platinum's natural white enhances the colourless appearance of the diamonds in the halo, creating seamless brilliance.

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.
