Here in New Zealand, greenstone is revered, as New Zealand greenstone has been used by the native Maori people for weaponry and jewelry.

Because of the natural variation in tone, the greenstone varies from dark to (relatively) light, as you can see in the photo below. You are welcome to nominate whether you want a dark or light greenstone ring, and I will do my best to supply you with your request, although I make no guarantees.

The greenstone rings are sized from US 4 1/2 to US 13 1/2, and are approximately 5mm (1/4") wide. 

If you are unsure of your ring size, take one of your rings to a jeweller where they can quickly size it for you.  Alternatively, we have an international ring sizing chart to convert British, Australian and other sizes to US or millimetres.
