While Jade Jagger and her hippie-deluxe lifestyle are often the subject of style and party pages, it is easy to overlook her status as a well-respected jewellery designer. Fairly early in her career she was employed to bring an edge of quirky design and gilded London youth to establishment jewellers Garrard. What she learnt there about precious stones and metals made a strong impression and has stood her in good stead for developing her own brand.

As she matures, her handwriting increasingly displays a distinct style that mixes boho chic with rock-chick elements such as skulls or arrows. She also employs the traditional techniques of Jaipur, India’s jewellery craft centre, where she spends a lot of time and has a permanent team. In recent collections Jagger has been working with large, Indian-sourced precious and semi-precious stones set in gold to make spectacular cocktail rings, and the production part of her range has been a regular among the fine-jewellery showcases at Joseph’s Brompton Cross flagship.

Now she has moved the gem and design content up a notch, working with large slices of ruby, emerald and sapphire, together with pavé diamonds, to create a series of one-off pieces that have just arrived in store. She has not used the clear, deep stones that are normally cut into great gems; hers are often milky and have inclusions, but they possess the advantages of great character and attractive prices. The colours and imperfections suit the organic shapes she prefers, and contrast with the tiny diamonds around them and the yellow or blackened gold settings. Jagger is also working with gem beads (including pretty but less exalted stones such as labradorite) for tasselled necklaces featuring tiny, brown diamond-set “disco balls”, and multi-strand bracelets. Prices range from £700 to over £13,000, and the styles can be made to order with different stones.
