It’s no surprise that this charming necklace looks like kids’ marbles, as they were often made of agate as well as swirled glass. Pebble London got its start looking for tumbled and faceted stones in India and Asia. They are inspired by tribal jewelry but have evolved to offer a fairly comprehensive range of jewelry an do custom work for leading designers as well. They note, “Pebble began as an excuse to spend lots of time exploring India, and our first collections used faceted and tumbled semi-precious stones we sourced throughout the country. Nine years later, and our travels now include India, China, Africa, Thailand, and South America, and we have expanded the collections to include metals, stones, wood, glass, coral, and amber.

We also use ancient excavated beads and glass trade beads produced in Europe in the nineteenth century.

Traditional tribal jewellery is a big influence, as is our love of natural materials, and we try to keep our designs as simple as possible, in the belief that you cannot improve on nature.

Pebble also sources traditional pieces from tribal groups in Africa, the Pacific, China, Afghanistan, Nepal, and India.

Over the years, we have worked with, or sold to many fashion designers, including Alexander McQueen, John Galliano, Cavalli, Issey Miyake, Mathew Williamson, Emilio Pucci, Allegra Hicks, Joseph, Nicole Fahri, and Donna Karan.”
