J C - Unknown mark on very good quality earrings. 

Jewel Crest - an Australian company that sells high-quality jewellery encrusted with Swarovski crystals.

Jewelcraft was the name used by Coro (US) in the UK for their Jewelcraft jewellery. The company were not allowed to use the name Coro because of the UK company Ciro. So the majority of sales were under the name Jewelcraft here in the UK. The dating is unclear but the name was used in the fifties through to the 1970s when the company stopped trading. 

Jewelcraft signatures are often in a script, and look out for their distinctive pear-shaped tag with concentric circles that seems to be used by only them. Signatures can be rubbed and difficult to find sometimes.
