Monica, because of the amount of questions we have been receiving we can only reply to Antique Jewelry Hallmark questions.
However we are able to provide expert opinion and a valuation on decorative items such as this antique Italian gold box that sounds wonderful! It is a paid service. Links are on the the bottom of the page.
