A rose quartz cabochon sits on the hand like a calm patch of warm, saturated colour - from a light pink to a deeper, slightly purplish shade depending on the light. The very big size of the stone keeps the band narrow and simple, so all the attention stays on the stone itself. This is a modern take on an engagement ring - no extra ornamentation, just a clear, uniform centre. Rose quartz has long been associated with tenderness and harmonious relationships, which fits well with the engagement character of this piece.

A specimen like this - with even, deep colour and a clean surface free of cloudiness - is easy to overlook, since good stones in this shade are becoming rarer. Silver and good coloured stones are rising in price, so buying at today's price seems like a sensible decision. The stone is set in refined European silver 925, of high alloy purity, free of nickel and other sensitising additives, which matters for sensitive skin. A layer of rhodium protects the surface from tarnishing and scratches, keeping the shine bright for years. The silver also bears the maker's mark establishing the piece's origin, registered with the French assay office.

For office wear, the ring pairs well with a smooth shirt and a blazer in muted tones - beige, grey or navy. The pink cabochon draws the eye with every gesture of the hand, without disrupting the calm character of the outfit. In the evening it works well with a simple dress in a cool shade, where the colour of the quartz gains even more depth. This particular cabochon, weighing 7.2 grams as part of the whole ring, remains a clear, calm focal point on the hand.
