opaque, transparent to translucent minerals

Are all garnets magnetic?
Garnets are more magnetic than any other transparent gemstones
due to the fact that they contain higher amounts of concentrations of paramagnetic iron and / or manganese. However, different types of Garnets that differ in their chemical compositions may also differ in their magnetic susceptibility.

Does feldspar have a metallic luster?
If a mineral can scratch glass and is non-metallic, suspect a silicate first, then perhaps one of the oxide minerals like corundum or rutile. Always suspect quartz first, then a feldspar.
If it’s metallic in luster, suspect an oxide
.
Is it a ruby or garnet?
Red garnets can have hints of orange or pink while rubies are vivid red with occasional purple or blue secondary hues
