The Crescent pieces are notable for their delicate patterns and superb workmanship, with elegantly detailed, fluted 18k yellow gold crescent moons, picked out by a line of diamond pave with a sparkling emerald star nestling in the new moon's curving arms. As befits a collection inspired by love, the Zambian emerald is from Gemfields' mines. Gemfields work with local communities, governments and conservation NGOs to ensure every gemstone sold supports health, education and livelihood initiatives, minimises effects on our environment and protects Africa's biodiversity.
