Top best answers to the question «Where do zircon crystals come from»

Originally formed by crystallization from a magma or in metamorphic rocks, zircons are so durable and resistant to chemical attack that they rarely go away. They may survive many geologic events, which can be recorded in rings of additional zircon that grow around the original crystal like tree rings.

  • Zircon is found all over the world, but gem-quality crystals are rare. Sri Lanka and Southeast Asia are the primary sources of gem-quality zircons. Sri Lanka produces material in all colors in gravels, including rare cat’s eyes. 1
