Metal free gemstone-like compound

Metal free gemstone-like compounds are gemstone like compounds compounds that:

• do not contain metal atoms
• do not necessarily need to but may include carbon

Or redundantly:

• Organic gemstone-like compounds with the condition on needing to contain carbon dropped.
• Odd gemstone-like compounds with the condition on not containing carbon dropped.
• A union of the former two

This gives a slightly bigger subclass of gemstone like compounds.
