Boulder opal ring description

The large stone in this ring has been selected out of hundreds of boulder opals to suit the tastes of someone who likes to get away from jewelry convention and wear something closely allied to nature.

Every time you look at your Boulder Opal Ring on your finger you will be reminded of its outback home.

The dark color of this stone reflects and contrasts nicely with natural skin color, or with a lighter outfit.

The natural boulder ironstone surrounds the precious opal strip which dramatizes blues and greens contrasting with the deep browns of the Australian Outback.

The recent opal nomenclature (official naming) has identified boulder opals, if they have the same very dark background as Lightning Ridge, as Black opals. So properly they can be termed black boulder opal

Boulder Opal Ring Explanation of Stone

Contrary to common belief, black boulder opals are not black. They were given this name many years ago when the first prospectors who found them were astounded to see the dark brilliant colors coming from an opal that traditionally was considered a light colored stone.

The Europeans had long known the value of precious opal from the Hungarian mines which as far as we know where all pale or light colored stones.

When opal was found in White Cliffs, and Coober Pedy, most of the stones were pale. Black Boulder Opal was one of the first stones found in Australian opal history.

It’s the dark in the background of the opal that causes the color to throw forward and have denseness and dynamic that the more delicate pale opal does not have.

    Hi. I think this is a lovely looking stone and ring. The specifications say it’s UK size N, which seems small for a man’s ring (i think my wedding finger is an R if I’m using the sizing guide correctly). Can you confirm the size for me and do you ship to the UK?
