I''m currently using Charles Carmona in the Los Angeles Jewelry district.
550 South Hill Street, Suite 1188 • Los Angeles, CA 90013-2412
TEL: (213) 624-0137 or (800) 909-4845
He''s an independent appraiser and a real nice guy.
I''ve also used Charles Carmona. Call him and discuss what you want him to do. He doesn''t have a sarin (many do not), but can show you H&A, idealscope, 30x magnification, etc.
