Skystone Sample C135 Freeform Cabochon Weight: 7.42 Carats / 1.48 Grams C135 is one of our oldest “polished” samples. It was polished nearly 30 years ago in our original goldsmith studio. This sample exhibits color zoning, veining, and a slight surface cavity (small imperfection). In fact, this is one of the original polished Skystones we presented to our in-house lapidary for polishing, to see if the material held geological properties. Our supply of material that we will be offering for sale is becoming extremely limited. Price includes insured, expedited shipping International buyers are responsible for all taxes, fees, and duties.
