Diamondere

Diamondere runs a made-to-order model where you choose a stone and setting separately, then specify the metal and ring size before anything is made. The coloured stone range is broad: blue, pink, and yellow sapphires, rubies, emeralds, alexandrites, and several other options all appear in the catalogue with accompanying certification.

Every stone comes with a GIA or equivalent certificate, and custom design requests are handled via consultation. Worldwide shipping is included, and the prices sit well below Zurich boutique levels for comparable material. Returns are accepted within a set window.
