Red/red system

An impressive red gemstone that hides gorgeousness and strength. Typical examples include ruby, red diamond, red spinel, almandine garnet, rubellite, red beryl, and blood red coral, but there are many others. Many have a pinkish or orange tinge, and even if you say red, the impression varies depending on the gemstone.
