The Zem Gem
Inspired by Zem’s love of brilliant things, The Zem Gem is a charm designed to shine all on its own or share the spotlight. The sparks absolutely fly between our Cat Gold™ (our custom 9K gold alloy) and stunning lab-grown, sustainably created diamonds. And the engravable back leaves room for your own personal stamp.
Cat Gold™ — custom 9K gold alloy
Nine karats of pure luxury made from 100% reclaimed gold that wears well and never wears off
Lab-grown, sustainably created diamonds, sourced by a US lab-grown manufacturer, are grown, not mined, to have a lighter impact on the planet
