18ct white gold Asscher cut halo engagement rings, handmade to order by our family workshop in the Cotswolds and set with a diamond you choose yourself. The Asscher cut is a square step-cut diamond with cut corners, much loved in the Art Deco era. A halo surrounds the centre diamond with a ring of smaller diamonds for extra sparkle and a bigger look.
The Asscher cut diamond
The Asscher is the square cousin of the emerald cut. Its deep step facets and cut corners draw the eye into the centre of the stone, giving a hypnotic, windmill-like pattern. First cut in 1902, it is the classic Art Deco diamond. The halo follows the outline of the Asscher diamond, so the shape reads clearly from across a room.
Why a halo?
A halo frames the centre diamond with a ring of small diamonds. The extra sparkle makes the centre stone look larger, so it is a good way to get a big look for less. Paired with a diamond-set band, it gives the most sparkle of all.
Why 18ct white gold?
18ct white gold is 75% pure gold, alloyed with white metals and finished with rhodium plating for a bright, mirror-white shine. It costs less than platinum and is lighter on the finger. As the plating wears, usually over a year or two, a hint of warmth can show; a quick re-plate brings it back. Want to spend less again? See our 9ct white gold engagement rings.
Choosing your Asscher diamond
Like the emerald cut, the Asscher shows its clarity, so choose VS2 or better. Look for a ratio between 1.00 and 1.05 for a true square. A G or H colour keeps the step facets crisp and bright.

Every ring is set with a centre diamond you choose yourself, natural or lab-grown, from our live stock. Each stone has its grading report, and the ring page shows the finished price before you buy.
