Sarah Loertscher / Tessa Blazey / Theresa Mink

Aptly, these scratched-surface rings merely scratch the surface of Sarah Loertscher's portfolio (some of which I've shown, above left). The Seattle artist, also known as lucymachine, draws inspiration from crystalline structures when working on her steel, silver and gold pieces.

Above: for more crystalline structures, check out these "mineral specimen" rings in pyrite by Australia's Tessa Blazey.

Bonus link: Austin's Theresa Mink offers up the uncommon combination of crystals and lucite! The piece pictured here features raw amethyst on top of clear plastic.

Even more jewellery:

• Paulo Segatto (Brazil) - crystals & gold


• Esther von Bach (Germany) - sculptural silver


• Judith Hoyt (New York) - collage on copper


• Britt Anderson (North Carolina) - pearls on loops


• Louise Grønlykke (Denmark) - wavy metal
