Ruby blende or garnete blende are two close trivial names for several dissimilar minerals,^[1]^: 112 with their appearance sometimes imitating red-colored precious stones, primarily natural garnets or rubies.^[2] In the scientific community, the systematic use of the term generally ended in the 19th century, with the transition to the modern system of naming minerals. Currently, both names are primarily used among mineral collectors and dealers, as well as geologists, miners and related trades.

Miargyrite is a rare steel-colored ore mineral with an internal garnet reflection, very fragile.^[1]^: 112
Pyrargyrite^[3]^{: 425–430} is a relatively rare ore mineral of dark red color with a diamond-metallic sheen, related to the previous one.^[4]^: 640
Proustite^[3]^{: 425–430} is a silver ore mineral, similar in composition to the previous two, and forms crimson crystals with a lead-gray sheen.^[4]^: 640
Sphalerite^[5] is zinc blende, some varieties of which have a rich red color with an orange tint.

^ All garnet blende have a metallic luster, which limits the perception of the internal color (reflex) of the mineral, so the conditions for photographing different samples are especially important. Miargyrite in the frame does not transmit light, it was shot in reflected light and therefore looks purely metalloid.
