THE MATERIAL LIBRARY
Garnet
A group of related minerals rather than a single red stone.
Colors & patterns
Red, orange, green, purple and other colors; deep red is especially familiar.
Typical origins
Different garnets come from India, Sri Lanka, East Africa and many other regions.
Hardness
About 6.5–7.5, depending on species
Choosing & setting this material
Ask which garnet species or variety is being offered. Cabochons can highlight rich color, and some included material can show a star.
Care & cleaning
Clean gently with lukewarm water, a little mild soap and a soft cloth, then dry. Avoid steam, ultrasonic cleaners, harsh chemicals and sudden temperature changes, especially when treatments are unknown.
Origins above describe typical sources of the material, not the origin of an illustrated or stocked stone. Hardness measures scratch resistance, not resistance to breaking. Confirm the identity and treatments of the actual piece.
