Gemstones, of infinite variety and beauty, have always been at the heart of our work and are a major source of inspiration, often the beginning of the creative process. There are so many wonderful stones which are rarely seen in the high street shops and whose names conjure up exotic places in the mind’s eye - topaz, tourmaline and andalusite, turquoise, lapis lazuli, tsavorite and moonstone -  as well as the ubiquitous diamond, sapphire and ruby.
