Buying guide
A Celtic knot is a woven, unbroken line with no beginning or end, often read as a sign of lasting connection. On this platinum knot ring the knots open out on the shoulders and lead into the center, while the rest of the band stays smooth. It gives a solitaire some detail without adding stones that need upkeep.
Platinum is dense and naturally white, so it holds prongs firmly and never needs plating to stay white. Instead of wearing away, it forms a soft satin patina that a jeweler can polish back to a shine. The weight feels solid on the hand, and the white metal works with both white and fancy-color centers.
The setting starts from about $1,950. That price is for the setting alone; the center is priced when you choose it.
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.
