An amethyst engagement ring draws out the stone's deep, dark purple, a hue that intensifies in the light and brightens with every movement of the hand. The cabochon cut gives the surface a smooth, slightly domed form, while two cubic zirconia stones at the sides add a discreet sparkle without taking the leading role away from the amethyst. The modern, understated band keeps attention on the stone, its line kept simple, and the big size means the ring sits well on the finger. It works equally well as an engagement ring or as a wedding band.

Each amethyst is examined carefully before it goes into the setting - what matters is the depth of colour and the clarity inside, free of cloudy inclusions. Silver and good coloured stones rise in price year after year, so buying this quality at this price makes sense today. The setting is refined European silver, sterling silver 925, further coated with a layer of rhodium, which helps the metal keep its shine for longer and need cleaning less often. The alloy contains no nickel or other irritating additives, making it comfortable even for sensitive skin. The silver bears a maker's mark registered with the French assay office, attesting to its origin. Amethyst's purple has long been associated with calm and clarity of mind, symbolism that suits a ring meant to accompany an important decision.

Styled with an all-black outfit, this ring finds a natural backdrop - a black turtleneck or a simple blouse won't compete with the stone, letting the amethyst catch the eye as the hand lifts in a gesture or holds a cup. It also pairs well with a dark coat or a leather jacket, where the cool grey of the accessories brings out the intensity of the purple. The big size and a weight of 3.8 grams give the ring a clear, but not heavy, presence on the finger.
