Only Use Natural and Certified Gemstone Good Tourmaline Cut and Shape Tourmaline is often cut into long rectangular bar shapes because of its elongated crystal habit. However, tourmaline is also available in various traditional and fancy shapes and a range of cutting styles. Due to the strong pleochroism of tourmaline, lighter colored tourmaline is typically oriented with the table facet perpendicular to the main axis, in order to display the richest hue. Good Tourmaline Color Tourmaline can occur in a wide range of colors from colorless to black. Black tourmaline is actually the most common color occurrence. Most tourmaline gemstones display two or more colors in a single stone (or two tones of the same color). Good Tourmaline Clarity and Luster Tourmaline is typically transparent to translucent. Opaque material is common for cat's eye tourmaline and schorl. According to GIA, most tourmaline is 'Type II' material in regard to clarity, which means tourmaline is often included. The level of inclusions can vary depending on the type of tourmaline, with some colors being more heavily included than others. Good Tourmaline Treatment Most tourmaline is completely untreated. However, some stones may be heated to improve color and clarity. Yellow, pink and red varieties of tourmaline may be irradiated to enhance color, although irradiation is nearly impossible to detect and does not normally affect value. Heavily included rubellite and Paraiba tourmaline may be clarity enhanced Read more Global Mining Supplies As we know, Colombia is the most important emerald producing area in the world, and Sri Lanka is known as the most important gem country in the world with Brazil and Myanmar.
