Questions abound with this material. Usually “OMG its beautiful but what is it? I’ve never seen anything like it before!” Well I should hope not. These beauties are called “Composites.”

Rutilation occurs naturally during the heat and pressure process involved with quartz formation. A simple understanding is that its a “captured” inclusion of another crystal by the quartz. The inclusion in this case is silicon dioxide. It has a gold color and grows from a base of hematite which is grey in color. Since quartzes have six sides, so can the silicon dioxide. Sprays of 3, 4, 5, and 6 are called stars. However stars must include the matrix from which they grew. Maximum rays is six because of quartz’s maximum number of sides and are very infrequent finds. Mining destroys some making availability even less.

What we’ve done is combine Black Onyx with the clearest cleanest Rutilated Quartz. We pick those pieces that will provide us with compelling stone designs in sizes that compliment SASA’s designs. The outcome is the exotic piece you see. When permanently bonded to the dark background of another stone, the combination becomes a composite. Anther background choice available in our shop is Lapis Lazuli.

This size 6.5 ring can be re-sized and is FREE to our customers.

If you are a set person, we have many others in earrings and pendants!
