Home Jewelry Production Gemstone Guide Tourmaline Lapidary Techniques: by Bruce A. Fry When cutting rough tourmaline, as with any colored gemstone variety, the lapidary must consider both color and weight retention. The unique complexity of cutting tourmaline comes into play not only with the great variety of colors, but with the distribution of color. Not all tourmalines have two or more colors, but when they do, the choice of cut can either blend or isolate the different colors. Tourmaline is the jester of gemstones - because it is so endlessly entertaining! The color down the c -axis (down the barrel of the pencil) is either the same color, a richer shade of the same color, or a completely different shade of the color than the a b color. Note: the a and b -axis, which are 90 degrees to the c -axis, must always be identical because of the geometry of the crystal. You can cut the stone to blend the c axis color and the a b -axis colors completely, but you can never eliminate the c -axis color in the face-up view of a practical gemstone. Color Mixing in Cut Tourmaline The shape of the tourmaline crystals also places limits on the mixing of color. This is particularly so when the tourmaline is in long, slender crystals with an optically dense

26. Gemstone Lapidary Cutting History - Cabochons Medieval Lapidary Techniques. A lapidary (edelsteinschneider) is an artisan who works with stone, minerals, or gemstones, forming them into decorative or functional objects. http://www.khulsey.com/jewelry/kh_jewelry_gemstone_cutting_history.html

Jewelry Home Page Lapidary History The Bead was probably the first gemstone cut used by man, dating back several thousand years. Limited by the tools available at the time, as well as the hardness of most gemstones, the simple bead or 'cabochon' were the logical choice for jewelry making and ornamentation. Stones where shaped by rubbing them with other stones, then polished using 'sand' as an abrasive. Intricately carved cabochon cuts known as ' Glyptic ' gem carvings, date back to the 7th millennium BC, and were popularized throughout ancient Egypt (scarabs), Indus Valley, and China (carved jade). Engraved 'Glyptic' gems were used as personal signets or seal-stones which could be impressed into wax or clay to create a signature. The examples above are of early Roman gemstone cuts using the pre-renaissance cabochon cut with several variations of cameo and intaglio styles. Medieval Lapidary Techniques A "lapidary" ( edelsteinschneider ) is an artisan who works with stone, minerals, or gemstones, forming them into decorative or functional objects. The term "lapidary" is derived from the word lapidaries , which were medieval 'treatises' on alchemy, mineralogy, chemistry and other sciences.

In most gems sawing, a thin circular blade usually composed of steel, copper, or a phosphor bronze alloy impregnated along the outer edge with diamond grit and rotating at several thousand surface feet per minute literally scratches its way through a gemstone. A liquid such as oil or water is used to wash away cutting debris and keep the stone and the saw blade from overheating, which could cause damage to both the stone and the saw blade. Several sizes of circular rock saws are frequently used by most gem cutters: A slab saw, typically 16 to 24 inches in diameter, is used to cut stones of several inches thickness into relatively thin slabs (often 1/8 to 3/8 inch thick).

40. Ancient Gemstones-Gem Archaeology And Gemology Ancient gem studies gem archaeology, gemology, scientific analysis, provenance, gem origin, ancient glyptic art and lapidary technology. http://ancient-gems.lthoresen.com/

PALIMPSEST RECOMMENDATIONS BACKGROUND DESIGN ... CONTACT GEM ARCHAEOLOGY smaragdos (a green-colored stone from which the term for the modern beryl variety "emerald" is derived). On Stones , Pliny the Elder's Natural History intaglios , has been the primary focus of study. Gemological and analytical study has been limited. Instead, the material attributes published on ancient gems have been reported anecdotally in successive journals, papers, and books, repeating for centuries erroneous interpretations of corrupt texts or observations based on sight alone, without the benefit of analytical verification. Peri Lithon, or On Stones , written in the fourth century B.C. by Theophrastus, is the most important text about gems of the Classical world. It is the earliest scientific treatise on any subject extant in western literature, and is the antecedent of our modern scientific system of classification. Although it survives only as a fragmentary book, On Stones presents a taxonomy of the gems known in ancient times, describing their origins, physical properties, and magical or other special attributes. Gemological study offers an illuminating perspective on the ancient literature and a re-assessment of archaeological literature, enabling correction of some inaccurate information and clearer rendering of opaque passages, particularly concerning gemstone origins and the nature of accidental alterations effected through burial, for example, or treatments applied intentionally to gems by the ancient lapidary.
