hi

- contrary to what people often assume, there is a policy on the GMB of not discussing values. This may appear unhelpful, but as you will appreciate such matters can be massively subjective, and as the saying goes 'one man's meat is another man's poison'. As individuals, how we value pieces differs enormously, and experience has taught that it's better to refrain entirely to avoid disputes, so sorry to be negative but regret this is a no go area here.
Glass from the Gulf of Venice is not my area, so regret cannot personally offer advice as to maker, and the lack of replies from others may be indicative of problems with recognizing your pieces as originating from Murano, despite the labels.
Might suggest that you contact professional sources of art glass in California, sending photos etc., requesting help with attribution/provenance - although appreciate such assistance might incur some cost.
Alternatively, auction houses might be prepared to help with information, but again their advice may not come free of charge.
Searching the internet and past auction sales is a possible way of locating similar pieces, and might also provide some guide to value.
Wish you luck with your search and would again suggest the option of returning to your dealer in La Jolla, and requesting help, assuming they are trading still.
