Two labradorite cabochons in these earrings shimmer with a cool, blue flash against a dark, almost graphite background. A slight turn of the head is enough for the stone's surface to reveal a new streak of light - a phenomenon jewellers call labradorescence. The simple, classic stud shape doesn't distract from this play of light, and the small size means the earrings sit well against the face and hairline. Labradorite is sometimes associated with clarity of mind and confidence - an association, not a promise, but a nice thing to keep in mind when putting them on in the morning.

We assess each of the two labradorites for colour and depth of reflection before it goes into its silver setting, and this selection translates into a clearly visible effect despite the stone's small size. Silver and good coloured stones are steadily rising in price, so buying at today's price makes sense. The piece is made from refined European silver, sterling silver 925 - a pure alloy free of nickel and other allergenic additives, which can be worn without fear of skin irritation. A layer of rhodium protects the surface against tarnishing and keeps the shine intact despite daily wear. The piece is stamped with the French maker's mark, which establishes the item's origin and is registered with the assay office in France.

These earrings feel most at home in relaxed, weekend outfits. Pair them with an oversized sweater in a cool grey and a shawl draped over the shoulders - the blue flash of the labradorite brings life to a muted, autumnal palette. With hair worn loose, the stone appears and disappears depending on how you move your head, an effect that shows particularly well with simple, sleek hairstyles that leave the ear exposed. They weigh just 2.4 grams, so wearing them all day stays light and comfortable.
