Description Dimensions: (7.4″ long) x (5″ wide) x (3.8″ thick) Weight: 2 lbs QUARTZ (Si02) silicon dioxide, is one of the most abundant minerals on earth. TITANIUM (ti), is one of the strongest metals known to man. These brilliant crystals are the result of part-nature and part-science. This natural quartz has been treated in a special process called Magnetron Ionization. In this process, the quartz is placed in a vacuum chamber in which titanium, combined with oxygen, is introduced and the two are bonded together at a molecular level. Quartz has a strong affinity to titanium and the two materials readily accept each other, acting as one after the bonding process occurs. The process uses only electricity to deposit the titanium layers. This results in a permanent, iridescent color effect of the surface of its crystals. The brilliant color is the result of optical interference effects produced by the varying layers of titanium. Since only electricity is used to create these colors, very little heat is involved and the integrity of the quartz is maintained. The method in no way harms the environment with hazardous chemicals or byproducts. TO CLEAN: Dirt, dust, and grease will cause the the surface to appear dull. Don’t fret! Simply wash with with water and a mild soap (if it’s just dusty, you may only need water). Avoid using any abrasives. Let air dry or blot dry with a clean soft cloth or a paper towel. Your specimen will be restored to its original beauty and brightness!
