Opals are a very interesting material. I know that I do not wear too much in the way of jewelry, but Koroit Opal is such an interesting material that I just may go and get a ring or a necklace made of that. Koroit Opal is a very dark mineral, but the number of variations in each rock make each piece of jewelry unique, stunning, and out of this world. The hints of blue, green, and even orange and brown in some rocks is what gives Koroit Opal the luster and interesting look that it has.

If you want to get a loved one a stone that virtually no one else has, pick up a Koroit Opal ring, necklace, or other type of jewelry.
