Signum Caeli — Sign of the Sky
A sapphire diamond ring with a clear sky-blue soul, Signum Caeli takes its name from Latin. Signum means sign, while caeli means of the sky. Therefore, the ring feels like a golden emblem. The deep oval sapphire anchors the face. Meanwhile, diamonds and blue sapphires form two bright paths.

As style context, GIA’s sapphire guide explains that colour is central to sapphire value. It also notes that strong blue tones are highly prized. Therefore, Signum Caeli speaks to the lasting pull of blue sapphire.
In fashion, coloured stones now feel more personal. For example, Who What Wear’s colourful gemstone jewellery editorial highlights blue sapphires among key modern stones. As a result, this ring feels expressive without feeling loud.
Also, Vogue’s high jewellery report places gemstones, craft, and story at the centre of jewellery value. This matters here because the panel feels like a small golden tablet. Each stone becomes part of its private mark.
Within Ojamie’s collection, Signum Caeli sits naturally among fine diamond rings. It also connects with the architectural feeling of the Phoenix collection. Therefore, this sapphire diamond ring feels made for collectors drawn to colour, structure, and quiet power.
