Laurence Coste

Laurence Coste is a London jewelry brand founded in 2006 by Paris-born designer Laurence Coste. The company’s published story begins much earlier: Coste started making pieces for friends as a teenager, moved to London in the mid-1980s, and studied art history at Christie’s. That background, along with her interest in color and composition, carries through collections designed to stand out without relying on a uniform silhouette.

The first boutique opened on Walton Street in Chelsea in 2006. Stores on Sloane Street and Brook Street followed, bringing the collection to three different parts of London. The Chelsea atelier connects design with production: the brand says its pieces are assembled and finished by hand in limited runs, so individual items may show subtle variations.

The collection includes earrings, necklaces, bracelets, rings, and brooches. The company works with agate, turquoise, lapis lazuli, mother-of-pearl, freshwater pearls, and other semi-precious stones; selected designs also use cubic zirconia. Its stated inspiration comes from nature, particularly the colors and textures of the sea and marine life. The result favors bold shapes, contrast, and color combinations that can serve as a focal point in an outfit.

Most pieces use a sterling silver base with gold plating; some are made on gold-plated brass. The brand clarifies that its pieces are not solid gold. Many earrings are available for pierced ears and as clip-ons, a useful distinction for shoppers who do not wear pierced styles. Product listings provide materials, dimensions, and options, which help when comparing a statement piece with how it may fit into everyday wear.

The bespoke service starts with a customer’s idea and a one-on-one consultation about stones, shapes, colors, size, and setting. A special-order service can also customize selected designs from the collection. The company recommends booking a consultation for a bespoke commission, although an appointment is not required for a general store visit. Pricing and timing depend on the design and materials rather than a single set fee.

Aftercare is part of the offering: the brand provides a six-month warranty and a lifetime care service that can include repairs, re-gilding, and restringing. Gold plating can wear with use, a point the company explains in its care guide. That support is especially relevant for handmade jewelry with stones and pearls, since customers can ask about maintenance at the boutiques and extend the life of a piece.

The three London locations serve different neighborhoods. The original Chelsea boutique is at 109 Walton Street; the Sloane Square store is at 149 Sloane Street, and the Mayfair boutique is at 20A Brook Street. The company says each store may carry exclusive pieces, while all three offer the collection and bespoke consultations. Customers can also shop online, making the boutiques an option for seeing materials in person, getting styling guidance, or discussing a commission face to face.
