gemstone
A rare and valuable mineral that is cut and polished to be used as jewelry.

The engagement ring was set with a sparkling gemstone.

The word is a clear compound of 'edel' (valuable, noble) and 'Stein' (stone). An Edelstein is therefore literally a 'precious stone.'
Sie erbte eine Kette mit wertvollen Edelsteinen.
She inherited a necklace with valuable gemstones.
The component 'Edel-' is also used in other words to express high quality or value, for example in 'Edelmetall' (precious metal: gold, silver) or 'Edelstahl' (stainless steel).
Gold und Platin sind bekannte Edelmetalle.
Gold and platinum are well-known precious metals.
Common verbs in connection with gemstones are 'funkeln' (to sparkle), 'schleifen' (to cut/polish), and 'fassen' (to set). You also often find the combination 'mit Edelsteinen besetzt' (set with gemstones).
Der Juwelier wird den Edelstein in einen Ring fassen.
The jeweler will set the gemstone in a ring.
In the figurative meaning, the qualities of a real gemstone—rare, valuable, and beautiful—are transferred to a person or thing in order to emphasize their special value.

darling / treasure
'der Schatz' and 'der Edelstein' both have to do with value. A 'Schatz' can be a collection of valuable things, for example gold, coins, or jewelry. An 'Edelstein', on the other hand, is a single valuable stone that is often used in jewelry. Figuratively, both can mean something or someone very valuable. They can be confused because gemstones can be part of a treasure. In practical terms: 'Schatz' is the broader and more general term, while 'Edelstein' refers more specifically to a particular valuable stone.
