Ruby and sapphire are a harder mineral than quartz, but are not thermally shock resistant. NEVER heat your ruby with an open flame. Always heat while placed inside of your banger or puffco. Let them cool naturally, do not use ISO or anything else, especially when still warm. With proper care, ruby and sapphire inserts can remain functional indefinitely. Inserts cracked from use will not be covered or replaced, so be careful when using ;)
