Is the tanzanite real?

Yes. Effy uses genuine tanzanite, the natural violet-blue gemstone from Tanzania, not glass or synthetic spinel.

How does it compare with Effy's gold tanzanite rings?

The gold versions cost more and resist tarnish better. This silver ring gives you the same stone type in a lighter, less formal setting.

Sterling silver tarnishes over time, especially with perfume, lotion and humidity. Store it dry and polish it with a silver cloth.

Yes, but tanzanite is softer than diamond or sapphire. Take the ring off for gym, gardening and heavy cleaning to avoid chips.

Tanzanite is a traditional December birthstone alongside turquoise and zircon, so it works well as a birthday or anniversary gift.
