As if the tourmalines Mt. Marie weren't temptation enough, on the mine road headed up to Mt. Marie, there are wild blueberry bushes. And just like the elusive perfect blueberry, not many true blue tourmalines have been mined in Maine. However, Mt. Marie has produced a few and this ring features one of them. Mined by Dennis Durgin, this stone measures 5.5 mm and weighs .60carats. It's set in a delicate floral white gold setting with full cut diamonds with a total carat weight of .90.
