Frequently Asked Questions
Do you charge for authentication opinions?
We're happy to give informal opinions on pieces via email—no charge for a quick take. For formal written authentication reports, we charge a fee based on complexity. Contact us for details.
Can I visit without an appointment?
During regular business hours, walk-ins are welcome. For dedicated time with a specialist, we recommend calling ahead to schedule an appointment.
Do you buy or consign jewelry?
Yes! We buy outright and offer consignment options for signed pieces. Visit our Sell Your Jewelry page for more information, or contact us directly to discuss your piece.
What brands do you specialize in?
We focus on signed pieces from major luxury houses: Cartier, Van Cleef & Arpels, Tiffany & Co., Bulgari, Harry Winston, David Webb, Boucheron, and others. Check our brand guides for detailed authentication information.
