Dark and shot through with blue light, labradorite is a stone that only reveals its character in motion. The cabochon cut brings out the labradorescence in full - the smooth, domed surface lets steel-grey and blue flashes travel across the dark background rather than scatter them through facets. Five labradorites set along the chain create a composition with a distinctly vintage weight, and 14.9 g of silver with a length of 48 cm plus an adjustable 9 cm extender allow the necklace to sit exactly where you want it at the neckline.

All five labradorites were matched so that the play of colour is even - each stone responds to light in the same deep blue tone. Good labradorites are increasingly rare, and silver prices are rising, which makes this price all the more welcome. The necklace is made from refined European sterling silver 925 - an alloy free from nickel and other sensitising additives, safe even for sensitive skin. The rhodium layer maintains the shine and protects the metal from scratches for many years. The piece is signed with the French maker's mark - a guarantee of quality and origin of the precious metal.

In summer the necklace pairs beautifully with a linen dress in off-white or light beige - the blue flash of the labradorites brings life to a muted background and draws the eye at the neckline. It works equally well with a loose shirt in fine cotton, where the vintage form of the necklace gives the look a clear character. In many cultures labradorite has been associated with inspiration and self-confidence - an association that suits jewellery worn close to the heart.
