Rainbow Sapphire And Diamond Eternity Ring
A wide 18K rose gold band channel-set with 30 square rainbow colour sapphires at approximately 1.85 ct, bordered by 66 round diamonds at approximately 0.55 ct.

Product Overview
Ninety-six stones in one band, in a colour sequence that has to run smoothly from one end to the other and meet itself without a jump. The sapphires are square cut and set in a row, so any gap between two stones shows as a dark line, and the colour order is laid out on the bench before setting starts rather than being decided stone by stone. The photographs on this page were taken at that bench.

- 66 round diamonds, approximately 0.55 ct total, bordering the colour row

How It Compares With The Alternatives
A technical comparison against other ways of solving the same problem. Nothing here is a performance claim against a named competitor product.
| Against a catalogue equivalent | This page publishes the metal, the karat, the stone grade and the dimensions the factory states, and says plainly where it states none. Catalogue product usually publishes adjectives. |
| Against buying the piece ready made elsewhere | Design, casting, setting, drilling and polishing all happen in the same building, which is what keeps the decisions with the person holding the stone rather than with a purchase order. |
| Against another family in this range | See the Rings page for what this family does that the others do not, and the related products below for the nearest alternatives. |
