925 Sterling Silver Corundum Thumb Ring HH0145

Thumb ring with corundum in 925 sterling silver

Usually, corundum is opaque, coarse - or fine-grained, grayish in color. Sometimes in large opaque crystals. Pure corundum is colorless. The wonderful colors characteristic of corundum, which make up the glory of this mineral, owe their origin to the smallest traces of other minerals. It has long been assumed that chromium is the cause of the color of ruby, and this was confirmed by experiments on the synthesis of this precious stone, conducted "with the use of chromium oxide as a coloring agent. It should be noted, however, that the content of chromium oxide in artificial stones is significantly higher than in natural ones. The variety of color of the latter can be explained by the presence in corundum of small amounts of other coloring agents, especially iron oxide. One of the most highly valued shades of red is the so-called "pigeon blood" - a red color with a slightly purple tinge.

Corundum is not natural!
When ordering, please specify with or without a stone.
