This minimalist solitaire ring draws all attention to a single faceted blue topaz, set in a plain, smooth band. The multi-faceted cut catches the light with every turn of the hand, and the stone's colour shifts from a cool sapphire tone to a lighter blue as you change the viewing angle. The ring's form is spare and understated, so the focus stays on the stone rather than the setting.

Only a small share of the reviewed rough makes it into this solitaire. The topaz must show a clean, saturated blue and high clarity, so selection is strict, and the result is high quality at a reasonable price. Silver and good coloured stones rise in price year after year, so buying a ring like this now makes sense price-wise. The metal is refined European silver, sterling silver 925 - the fineness confirms the purity of the alloy, free of nickel and other harmful additives, which rules out skin irritation. A rhodium layer protects the silver from tarnishing and dulling, so the shine lasts longer. The ring is stamped with a maker's mark registered at the French assay office, which confirms the metal's origin.

A solitaire like this sits comfortably on the hand in everyday, understated outfits. A soft knit jumper in shades of grey or beige, paired with linen or cotton - in such a monochromatic styling, the blue of the topaz naturally draws the eye. It can be worn alone on the index or middle finger, without other rings nearby, so the solitaire form stays clearly visible. At 2.4 g, the ring sits lightly on the hand and doesn't get in the way of everyday gestures.
