These Diamonds quartz (quartz crystals) are natural and uncut. One facet is covered with an 18K gold plate to create a unique and sophisticated piece of jewelry. Each gold plate is made individually to fit a particular facet. If you wish, you may choose which facet to cover. These pieces will give you a different shine depending on the angle of the light. Sometimes a clear sparkle, other times the gold may add a touch of warmth.
