In our blog: The Importance of Cut in Faceted Stones

and, last but not least:

The Work of Judith Kiriazis   Original design jewelry with dichroic glass, precious metals, and gemstones by the owner of this site


 While the term "gemstones" can refer to any precious or semi-precious material used in jewelry, people most often equate gemstones with precious and semi-precious transparent faceted stones, such as diamonds, tourmalines, topaz, etc. However, the world of gemstones is much broader and varied than just these. Heart of Stone Studio does offer faceted gems, but our emphasis is on the world of translucent and opaque gemstones, which, instead of being faceted, are cut in a variety of shapes with flat backs to enable easy incorporation into jewelry designs. These flat-backed, domed-top gems are called "cabochons" or "cabs," and we invite you to browse through our dozens of pages of cabochons which originate all over the world and come to you in every color of the rainbow. Another emphasis of our website is a special type of flat-backed stone covered with tiny crystals, called "druzy" (also spelled "drusy.") Drusies come in a variety of natural colors, as well as with various metallic coatings, and they add sparkle and interest to any jewelry design. We are proud to offer what is probably the web's largest selection of high-quality drusies. We hope you will become part of our Heart of Stone Studio customer community. Every one of our stones is hand-picked and guaranteed to please!
