The deep violet of the amethyst in this ring shifts shade with every movement of the hand - one moment a dark purple, the next a lighter, almost pink glow at the edge of the cabochon. The classic, understated setting doesn't draw attention away from the stone, and the very big size keeps the amethyst as the main focus of the whole piece. This design is meant as a wedding and engagement ring - simple in line, but with character that holds up well to everyday wear.

An amethyst of this kind, pure and even in colour, isn't easy to overlook among other stones - finding another with a similarly deep colour is far from simple. Silver and quality natural stone prices rise year after year, so buying this ring now makes sense price-wise. The cabochon is set in refined sterling silver 925 of European quality, coated with a layer of rhodium - this metal protects the surface against tarnishing and scratches, so the ring needs cleaning less often and keeps its shine for a long time. The silver bears a maker's mark struck into the metal, registered with the French assay office, which attests to its origin. The alloy contains no nickel or other sensitising additives, which matters for sensitive skin on the hand where the ring is worn. Amethyst has long been associated with calm and clarity of mind, and in many traditions it was regarded as a symbol of inner balance - hence its popularity in rings for this occasion.

Against total black - a black turtleneck or a plain blouse - the violet of the amethyst stands out clearly and draws the eye with every movement of the hand. It also looks good with a muted, grey office outfit, where the stone acts as a spot of colour on the hand. The size of the stone and its deep colour mean the ring needs no extra jewellery on the same hand - the gesture alone is enough.
