Are dark or light emeralds better?
When it comes to emerald, many people expect a deep, dark green. But often, the stone they fall in love with is much lighter! Lighter gems reflect more light, making them livelier, and most people prefer them to a darker green with less brilliance.
Does emerald scratch easily?
Contrary to popular belief, emeralds are very resistant to scratches. A direct measure of this is the Mohs Hardness Scale. Any mineral on the scale can be scratched by a mineral the same rank or above it, but cannot be scratched by anything below it.
