Priced at a nicely economical £75 apiece, the Druzy rings feature, depending on the version you choose, either craggy crystals sprouting from its base or a deep V revealing lovely natural layers. It almost makes us wish we'd paid more attention in science class.
The rings come in pink, purple (contrasted with a lovely brown base), navy, and black, which basically means there's one to match just about everything in your wardrobe...even those bloody mittens.
