Craftsmanship You Can Feel
Every diamond is chosen by eye for its cut, fire and brilliance. Our lab-grown diamonds are real diamonds, chemically and optically identical to mined stones, and IGI certified.
Each piece is cast in solid 14K white or yellow gold and finished after you order it, so it is made for you rather than taken from a shelf.
Your center stone and every accent diamond are set and secured by our master jeweler, then polished so the setting sits smoothly and safely on the hand.

Ring Sizing Guide
Every Alessa ring is made to order in your size. Use one of the two methods below, then find your size in the chart.
- Choose a ring that fits well on the finger you are buying for.
- Place it on a ruler and measure the inside diameter, from inner edge to inner edge, in millimetres.
- Find the closest diameter in the chart below to see your size.
- Wrap a thin strip of paper or string around the base of your finger.
- Mark the point where it overlaps, then lay it flat and measure the length in millimetres.
- That length is your finger circumference. Find the closest match in the chart below.
Tip: measure at the end of the day when your fingers are warm, and make sure the ring can pass over your knuckle.

Between two sizes? Choose the larger one. Wide bands sit more snugly, so consider going up half a size.
