Asscher Cut Engagement Rings

The Asscher Cut

Asscher Cut Engagement Rings

An asscher cut diamond is a square step cut with deeply cut corners, so it reads as an octagon from above, and concentric facets that draw the eye into the center like a hall of mirrors. It is the emerald cut's square cousin and the most architectural diamond made, a cut from 1902 that has never needed updating. Every asscher cut engagement ring here is made to order in our Los Angeles atelier, modeled to the exact measurements of the diamond you choose.

Asschers face up smaller than any other shape at the same carat weight, because the cut is deep and the weight sits below the table. What you get for that is depth: an asscher has a quality of looking into the diamond rather than at it, and it suits art deco and geometric settings in a way no brilliant cut can.

Two ways to own one

Build your ring. Choose a setting below, then pair it with a natural or lab diamond from our inventory. A ROSI™ Score Report, our gemological intelligence, reads the cut performance and fair market position of any natural diamond you are considering, and John Anderson, our Lead Gemologist, reviews the shortlist with you.

Choose a Select ring. The Select rings arrive complete, with an IGI certified lab diamond already matched to the setting in the carat weight you choose.

How to choose an asscher cut diamond

• Clarity. VS1 or better. The step facets and open center show inclusions that a brilliant cut would hide. Clarity is worth paying for in this shape.
• Color. G or better in platinum and white gold. H in yellow gold. The deep pavilion holds color.
• Ratio. 1.00 to 1.05, a true square. An asscher that reads rectangular is an emerald cut; the octagonal outline depends on the square.
• Corners. Wide, even cut corners are what make an asscher read as an octagon. Small corners make it read as a plain square.
• Setting. Four prongs on the corners, or a bezel, which suits the shape perfectly. Art deco and geometric settings with baguette or trapezoid sides are the natural pairing.

Talk to a jeweler before you decide

An asscher is chosen by people who know what they are looking at, and the diamonds that reward them are not the ones with the best numbers on paper.
