Calibre Cut Ruby Ring
A calibre cut ruby ring combines geometric stones with fiery red colour, making it a sought-after choice for vintage jewellery collectors.
Calibre Cut Ruby Ring
A calibre cut ruby ring is primarily defined by stones shaped precisely to fit closely together within a mount, often forming bold geometric patterns. Buyers searching for a calibre cut ruby ring will encounter various interpretations, from streamlined Art Deco designs to heavier Retro Modern styles.
Alongside rubies, these rings frequently incorporate diamonds, sapphires, and platinum settings to enhance the visual impact. The combination of calibrated red stones and brilliant white diamonds creates the distinctive contrast that defines this group.
How they were made
Makers utilised precious metals such as platinum and 18ct white gold to construct secure, durable settings that could hold closely fitted stones. The metalwork often involves intricate detailing, such as millegrain edges or structural shapes like tank and crossover motifs.
The central rubies are cut in specific geometric shapes, including French cuts or calibre styles, to align seamlessly with surrounding diamonds. Old cut and rose cut diamonds are commonly used to add texture and softer brilliance next to the crisp lines of the rubies.
