Expert opinion

This ring has been assessed by our in-house gemmologists:

The rubies are most likely to be from the old Burmese mines.

Comments

Calibre cut gemstones were worked into special shapes to fit into a specific area. Each gemstone would be fashioned so they sit right next to each other within a channel, with no metal in between visible from above. They would usually be held securely in place with a rubover or millegrain setting – a fine piece of secure metal bordering the stones. Calibré cut gems were usually faceted into small step-cuts or could also be polished to create tallow tops or miniature cabochons.

To produce this technique on an often minute scale required incredibly skillful and precise fashioning.

Condition report

The ring is in good condition.
