A faceted amethyst opens up in the light with a series of small flashes - with every movement of the hand the facets catch the light differently, and the stone's deep purple takes on a cooler or warmer tone. Two cubic zirconias on either side add sparkle without taking the lead role away from the amethyst. The ring's classic, understated band doesn't compete with the stone - the whole composition stays elegant and clear, just as befits a ring for an occasion such as an engagement or a wedding.

Every amethyst is examined carefully before it goes into the setting - what matters is the depth of colour and the clarity of the interior, since only a stone like that gives this deep, even colour. Good amethysts are rising in price along with silver, so a ring of this quality and price is worth considering now. The rhodium layer on the silver protects the surface against tarnishing and scratches, so the shine lasts long without frequent cleaning. The 925 fineness confirms the purity of the alloy - refined European silver, free of nickel and harmful additives, so the metal doesn't irritate the skin. The French maker's mark confirms the origin of the metal, and the European quality of the workmanship is visible in the precision with which the stone and the cubic zirconias are set. The purple of amethyst has traditionally been associated with calm and clarity of mind, which fits well with the character of a ring for an engagement or a wedding.

In a total-black outfit - a black turtleneck or a simple blouse - it's the amethyst that draws the eye when the hand rises in a gesture or during a handshake. The purple flash against black works more strongly than against coloured clothing, since nothing distracts from it. A ring like this also sits well with a simple sweater or a classically cut shirt - all that's needed is for the hand to stay at the centre of attention. Its medium size and weight of 3.1 grams mean it can be worn easily every day, not just on special occasions.
