Word structure
The noun 'Kostbarkeit' (treasure/preciousness) is derived from the adjective 'kostbar' (valuable/precious). The ending '-keit' forms a noun that describes the quality expressed by the adjective.
EXAMPLE
Er schätzte die Kostbarkeit dieses seltenen Buches sehr.
He greatly valued the preciousness of this rare book.
Countable vs. uncountable
'Kostbarkeit' (treasure/preciousness) can be countable or uncountable. In the plural ('die Kostbarkeiten' — treasures), it refers to valuable objects. In the singular without an article, it describes the abstract quality of being valuable.
EXAMPLE
Das Museum bewahrt seine schönsten Kostbarkeiten in einem Tresor auf.
The museum keeps its most beautiful treasures in a safe.
Abstract use
In its abstract meaning, 'Kostbarkeit' (preciousness) is often used to emphasize the ideal value of non-material things. Typical phrases are 'die Kostbarkeit des Lebens' (the preciousness of life), 'der Freundschaft' (of friendship), or 'des Augenblicks' (of the moment).
EXAMPLE

Kostbarkeit vs Wert
value
'der Wert' and 'die Kostbarkeit' can both express that something is valuable. 'Wert' is more neutral and can mean the exact financial price or an important significance. 'Kostbarkeit' sounds stronger and more special: it often refers to a rare, expensive, or highly treasured object. The words can be confused because both have to do with value. For exact prices, use 'Wert'; for something very special or precious, 'Kostbarkeit' fits better.
Kostbarkeit
Im Museum liegt eine alte Kostbarkeit aus Gold hinter Glas.
In the museum, an old gold treasure lies behind glass.
Wert
Der Wert der Uhr wurde von einem Experten geprüft.
