This delicate, modern rose quartz ring pairs the clean, geometric silhouette of a solitaire with the warmth of a natural stone. The cabochon cut smooths the surface and gathers the light into a single point, so the colour appears richer and the flashes only catch as you turn your hand. It's a solitaire and promise ring in one - just as easy to wear every day as to give as a gesture of affection. Rose quartz has long been linked to love, tenderness and harmonious relationships, though here it's the calm, even colour that takes centre stage.

Only a small share of the carefully checked raw material makes it into this piece - what matters is purity and an even shade, free of flaws or cloudiness. Silver and precious metals keep rising in price, and good-quality natural stones are becoming harder to find, which makes a purchase like this a sound one right now. The ring is made of refined European 925 silver, coated with a layer of rhodium - a hard metal resistant to scratching, which protects the surface from tarnishing and keeps its shine for a long time. A pure alloy free of nickel and harmful additives means even sensitive skin can wear it without irritation. The piece is stamped with the French maker's mark, which attests to the silver's origin.

Its small size and weight of 2.3 grams mean the ring sits light and almost unnoticed on the finger, until it catches the light. For the office, it works well with a smooth shirt and a jacket in a muted colour - grey, beige or navy - where the pink cabochon adds a warm touch without being too much. It pairs just as well with a simple sweater or a collarless shirt, when a discreet, feminine shape is what counts. A gentle turn of the hand is enough for the stone to draw the eye.
