Amethyst stud earrings play with violet depth at every turn of the head. Two cabochon-cut amethysts have a smooth, domed surface that gathers light into a single point and reflects it back in a dark, saturated purple. This is a colour jewellers have long associated with calm and clarity of mind, and here it takes a simple, distinctly classic form, free of unnecessary flourishes. The medium-sized studs sit close to the earlobe, so they don't pull at the ear or interrupt the line of the neck.

Each of the two amethysts was inspected individually and chosen for pure, even colour free of cloudiness - this selection is exactly what makes it possible to achieve high stone quality without inflating the price. Silver and good coloured stones are rising in price, and stones with this depth of colour are harder to find today, so buying at this price makes sense now. The setting is made of refined European 925 silver plated with rhodium - this metal is hard and scratch-resistant, so the shine of the studs doesn't dull over time. The alloy contains no nickel or other harmful additives, so even with prolonged wear it won't irritate the skin around the ear. The maker's mark stamped on the silver, registered with the French assay office, attests to the origin of the metal.

These earrings come into their own in the evening - with a little black dress, a silk blouse or a satin top, when the hair is swept back behind the ears to reveal the line of the neck. The purple of the amethyst draws the eye more strongly than it would amid a lot of other jewellery, so it's worth keeping the rest of the look understated, without an additional necklace or chunky rings. In their classic cabochon form, these studs stay discreet by day and striking after dark.
