Morphology
The figurative sense 'the most valuable assets' is directly inferable from combining 'crown' (a symbol of highest status) with 'jewels' (very valuable items): together they naturally denote the most prized possessions. This metaphorical extension is straightforward and found in many languages, so a B1 learner who knows both words would likely understand the figurative meaning.
Etymology
Crown jewels is also used as a metaphor: imagine a king keeping the bright crown and valuable jewels locked away as the things he must protect most. So people call a company's or project's most important and valuable parts its 'crown jewels', meaning 'the items that must be kept safe'.
