The English name for Ruby is Ruby, which is derived from the Latin Ruber, meaning red. The mineral name of ruby ​​is corundum. The chemical composition of ruby ​​is aluminum oxide (Al2O3), which is red to pink due to the trace element chromium (Cr3+). It is a trigonal system. The crystal form is often in the form of a barrel, a short column, or a plate. The aggregates are mostly granular or dense blocks. Transparent to translucent, glass luster. The refractive index is 1.76-1.77, and the birefringence is 0.008-0.010. The dichroism is obvious and heterogeneous. Sometimes it has a special optical effect - the starlight effect, which reflects the fascinating six-shot starlight under the illumination of light, commonly known as the "six-way line." The hardness is 9, and the density is 3.95-4.10 g/cm 3 . No cleavage, crack development. Ruby emits red and dark red fluorescence under long- and short-wave ultraviolet rays. So, how to clean ruby? Xiaobian to tell everyone:
1. Thorough cleaning method: Use a small bowl or tea cup to hold the warm water after the defensive salt is dissolved, soak it for 10 hours each time 10 grams. Finally, dry it with a soft, lint-free cloth. The defensive salt cleaning has a great influence on the artificially treated ruby, which will make the artificial processing part appear. But it does not affect the natural part. And cleaning the ruby ​​with salt every month, can eliminate the dead skin tissue on the ring to avoid fungal growth and prevent the occurrence of skin diseases.
2. Cold water immersion method Use a small bowl or teacup, put the defensive salt into the bowl, immerse the ruby ​​in the water for about 30 minutes, then use a small brush, gently scrub around the spar, and then wave in the water for a while. Take it out and wipe it off with a paper towel.
