Garnet

About this episode

A deep red garnet is a familiar sight in antique jewellery. But the same mineral group also includes purple-red rhodolite, bright orange spessartine and green demantoid. Some are plentiful; others are much harder to find, particularly in larger sizes. Matthew and Fenia look at what connects these stones, how their different compositions affect their appearance, and why garnet deserves a closer look. They trace its place in carved ancient gems and Victorian jewellery, explore the stories attached to its pomegranate-like colour, and open Fabergé’s Winter Egg to find the tiny green garnets inside. Matthew also considers the qualities that matter when choosing a piece, from colour and cut to the size of a demantoid, before Gem Trivial Pursuit takes a pomegranate theme. Key Takeaways • Garnet is a group of related minerals with a shared crystal structure and different chemical compositions. • Its colours include the familiar reds, purple-red rhodolite, orange spessartine and the greens of tsavorite and demantoid. • Garnet has a long jewellery history, from carved ancient stones to Victorian necklaces, brooches and earrings. • Fabergé’s 1913 Winter Egg contains a basket of white-quartz wood anemones with demantoid garnets among its materials. • Colour, cut, clarity and the rarity of a particular variety in a given size all affect value.
