Frequently Asked Questions

A jewelry appraisal is a detailed, written report prepared by a qualified appraiser that describes your jewelry and assigns a specific value for a defined purpose such as insurance, estate planning, resale, or donation. Appraisals are important because they provide proof of ownership, accurate documentation, and an up-to-date value in case of loss, damage, or sale.

Appointment times depend on how detailed each piece is. Plan for at least 1 hour per item, and we will give you an estimated timeframe when you schedule your appointment.

Appraisals should be updated every 2 to 5 years to ensure your insurance coverage remains accurate and reflects current market values.

Yes — each appraisal report is tailored to your specific needs, whether you require an insurance replacement value, fair market value for resale, estate division value, or a liquidation value.

Yes — in most cases, we can provide on-site evaluations at your convenience.

An appraisal is a formal document prepared by a qualified appraiser that describes a jewelry item in detail and assigns a value for a specific purpose, whereas a valuation is the expression of the item’s monetary worth and may not always include a formal appraisal document.
