Buying guide
An Asscher is a square step cut with cropped corners. Its long, flat facets form rings of light that draw the eye toward the middle, often called a hall-of-mirrors look. Step cuts show clarity and color more openly than brilliant cuts, so a large Asscher rewards a clean stone. At 3.5 carats the outline reads as bold and geometric, and it pairs well with straight, simple bands.
Accent stones add to the ring's overall weight; the 3.5 carat figure is the center stone alone.
Every ring comes in white, yellow or rose gold (10K, 14K or 18K) or platinum. Platinum is dense and naturally white, while gold is lighter and comes in three colors. Prices start from about $3,150, and most rings are between about $3,450 and $3,650 in 10K gold with the center included; platinum and higher karats cost more.
Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.
