Origin and formation of ruby
For the origin of the ruby, there are currently written descriptions mainly in the Moyu River, which may be related to the mysterious and mineral composition of the river basin, such as ruby, topaz, jade, violet, etc. Scarce jade species are prolific here.
There are two opinions about the formation of ruby. One opinion is that jadeite is formed by the infiltration of minerals such as iron oxide; another opinion is that red jade is a natural primitive jade, which is the process of jade formation. Naturally formed, of course, iron ions are the cause of coloration - iron ions are formed together with aluminum atoms in the tremolite, rather than "contaminating" coloring.
According to the original red jade color, mainly dark red and burgundy, "the purple red is like coagulation" is the original red jade, the original red jade color is uniform inside and outside the color, the whole body color is not big, the light transmission is good, jade The structure is relatively tight, the inadequacy is that the color is not bright enough, and sometimes the interior is red with a blood-red silky or radial shape.
Ruby standard
Because the ruby ​​is very rare, too strict standards may hinder the collection, which may make the rare ruby ​​and Tibetan friends miss. I think the collection of ruby ​​should follow the following criteria:
1. The red jade ingredients must have a flash stone and an actinolite as the main components.
2. Hardness must meet the standard of nephrite.
3. Must have a certain light transmission.
