The faceted blue topaz opens up in this ring with a classic, clean line of colour. The facets are arranged so that light travels deep inside and returns as a cool, blue flash, without a trace of cloudiness. On either side, two cubic zirconia stones complete the composition, adding a discreet sparkle without drawing attention away from the main stone. The ring's form is classic and understated, designed to work equally well as an engagement ring or a wedding band meant to be worn every day.

We assess every topaz for colour and clarity before it goes into its setting, and in this piece the blue hue is even and deep, with quality that matches the price, which remains reasonable. Silver and good coloured stones are rising in price, and topazes of this colour saturation are becoming harder to find, so buying now makes sense. The ring is made of refined European 925 silver, coated in rhodium - a hard metal resistant to scratching, which keeps its shine for a long time and protects the surface from tarnishing. The alloy contains no nickel or other harmful additives, so the skin stays safe even with daily wear. The French maker's mark on the piece confirms the origin of the metal.

For the office, the ring pairs well with a smooth shirt and a blazer in muted, cool tones - navy, grey and deep blue set off the colour of the topaz without competing with it. The gesture of a handshake or holding a cup further shows off the play of the facets. In the evening, the same form works just as well with a simple dark dress, where the cool blue of the stone remains the main point that catches the eye. The medium size and weight of 3.1 g mean the ring sits light and unnoticeable on the finger through everyday movement.
