Buying guide
Filigree is delicate openwork in the metal, lace-like curls and scrolls that let light and air through. On these rings it sits in the gallery under the center and along the shoulders, so the detail shows from the side. It gives a filigree lab-grown ruby ring an heirloom feel without making the top heavier.
Every ring here has pavé lab-grown diamonds, so the red center sits in a bright frame. Openwork can collect dust; a soft brush with warm soapy water keeps it clean.
A lab-grown ruby is the same red corundum crystal as a natural ruby, grown under controlled conditions. It rates 9 on the Mohs scale, just below diamond, so it holds up well in a ring worn every day. The color is even and the stone is usually very clean, at a far lower cost than a natural ruby of similar size and color.
Each design offers 1 to 9 carats total weight. Yellow and rose gold show filigree in a warm tone; platinum, white gold and silver give it a crisp, lacy look. Prices start under $400, and most rings sit between about $840 and $1,030 at their smallest size.
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.
