Gems, which are highly priced than crystals, are rare minerals found in the earth. Gems can be said to be precious and valuable stones which are used more in jewellery. Crystals, which are pure substances, consist of molecules that are arranged in a geometric pattern.
Gems come with mineral bases like diamonds or rubies and with organic bases like amber. Crystals are solid materials which have atoms, molecules, and ions fixed in regular patterns that extend in three dimensions. Crystals are also called materials that have well-patterned geometric shapes.
