	Groups can contain two or more minerals with similar properties and structure but slightly differ in chemical properties. For example when one chemical element replaces another in the same formula.

		+	====Garnets====
		+	Garnets are classified as a 'group' unlike other families that are classified as a 'species'. This is because the color variations in garnets are due to differences in their actual chemical structure rather then the presence of impurities as in other gem families.

	===Variety===		===Variety===
		+	Color variation in the different varieties of a species are caused by the presence of minute impurities.
