How are Gems Cut and Polished?
A citrine quartz preform . . . . . . . . . . and the finished faceted stone. T he process of cutting and polishing gems is called gemcutting or lapidary , while a person who cuts and polishes gems is called a gemcutter or a lapidary (sometimes lapidarist). G emstone material that has not been extensively cut and polished is referred to generally as rough . Rough material that has been lightly hammered to knock off brittle, fractured material is said to have been cobbed Rough corundum A ll gems are cut and polished by progressive abrasion using finer and finer grits of harder substances. Diamond, the hardest naturally occurring substance, has a Mohs hardness of 10 and is used as an abrasive to cut and polish a wide variety of materials, including diamond itself. Silicon carbide, a manmade compound of silicon and carbon with a Mohs hardness of 9.5, is also widely used for cutting softer gemstones. Other compounds, such as cerium oxide, tin oxide, chromium oxide, and aluminum oxide, are frequently used in polishing gemstones.

    The Chevron Technique
    Our Chevron Beads differ from most antique and contemporary Chevrons in the materials and techniques used to make them. Molten clear glass and solid bars of colored glass are the starting materials, differing from the traditional method of having pots of molten colored glass available. The advantage of our method is seen in the unique and unusual combinations of different colors in a single bead. All Chevron Beads are made in two stages. The first uses glassblowing techniques, and consists of building up layers of color on a blowpipe, then stretching that gob into a long tube. The second stage uses lapidary techniques to turn the cooled tube into finished beads. In both stages, we have taken the Chevron in unique directions. The glassblowing stage of the Chevron process begins with a thick-walled bubble on the end of a blowpipe. Layers of color are added to the outside of this bubble in four possible ways. The first way, gathering, is the traditional method of dipping the bubble into a pot of molten colored glass. The second way is to heat a chunk of glass on a rod until it is molten, dripping it onto the bubble while still soft. This way results in an appearance similar to the gathering method. A third way results in thinner layers of color, and is accomplished by blowing a thin bubble and wrapping it around the original bubble. The fourth way is done by applying pre-formed glass canes to the surface. We use some or all of these four layering methods in a single bead.

    Date: Tue Jan 07 21:57:42 2003 =========[ Make a Donation - http://www.ganoksin.com/donate ]========= Hello all! I am new to this list and this is my first post/question. Here is my situation: I've recently been taking faceting classes at a nearby gem/minerals club and I like it, a lot. The club itself is excellent... modern equipment, clean, and nice people. However, I can only go to the club meeting/workshop once a week or less because of my location, schedule, etc. And once a week is not enough to satisfy my thirst for faceting! Anyways, my question is this: aren't there less expensive alternative to faceting at home other than modern faceting machines? They easily cost $1000! I asked around for cheaper alternatives at the club and they all just recommended facetrons/ultratecs/etc... Don't many people use primitive methods of faceting, like the device seen on http://www.rockhounds.com/rockgem/articles/laplap.html

    January 2000 Friends of Kreg Scully
    It is with great sadness that we report that Kreg Scully, the noted gem artist, has been diagnosed with advanced melanoma cancer. In addition to his own gem work, Scully has worked to further the gem arts through education and contributions of his own time and energy to many organizations, museums, and other venues that further the public's appreciation of gemstone art. He has been an invaluable member of the gemstone community and has touched all who know him with his passion and sincerity for his art. Scully has been the sole financial support of his family; currently unable to work, he and his family could use any financial help to cover his extensive medical bills as well as simple living costs. A legal trust has been drawn up; donations will be placed in a bank account and funds will be made available to the family via the trustees. Contributions are made directly to the trustee in the form of a check written to: Kreg Scully and Family Cancer Trust and sent to either 2220 Koppers Building, Pittsburgh, PA 15219, or 4753 Ardmore Lane, Virginia Beach, VA 23456. The trust has been drawn up in accordance with all pertinent laws and has a Federal Tax ID number; all contributions are tax deductible. To receive a copy of the trust documents themselves, please send a SASE to Arthur Lee Anderson, P.O. Box 8525, Fredericksburg, VA 22401. We at Lapidary Journal send our sincere best wishes to Kreg and his family, and our thanks to our readers for their help.

    The introduction of the lapidary engraving wheel in Mesopotamia
    Scanning electron microscopy provides an insight into the lapidary techniques of the ancient Near East. Engraved features on quartz cylinder seals have been compared to those produced experimentally, leading to a radical reassessment of the date for the introduction of the engraving wheel. Key-words : scanning electron microscopy, cylinder seal, stone, engraving technique, wheel-cutting, replication et al It emerged in our earlier investigation that simple flaking techniques of engraving prevailed in the late 4th millennium BC and throughout the 3rd millennium BC, with no evidence for the use of wheel-cutting techniques. However, wheel-cutting became the dominant technique in the 1st millennium BC. We have therefore focused the present study upon the changes that occurred during the 2nd millennium, with the aim of establishing the chronology of the introduction of the wheel and the other technological changes with which it was associated. Methodology
    c . 3100 BC to c These are the opening paragraphs only of this article in 'Antiquity'. For the full text with illustrations see the journal itself.
