DIAMOND & FINE JEWELRY APPRAISALS
Understand Exactly What You Own.
Diamonds and fine jewelry can vary dramatically in quality, rarity, craftsmanship, provenance, and value.
Our appraisers independently examine and document each piece to help you understand exactly what you own, how it is constructed, and the appropriate value for the intended purpose of the appraisal.
Independent. Precise. Informed.
WHY A PROFESSIONAL JEWELRY APPRAISAL MATTERS
Details Matter.
Two pieces of jewelry that look similar can have very different values.
Diamond quality, gemstone origin and treatment, metal content, craftsmanship, designer attribution, condition, age, and market demand can all materially affect value.
A professional appraisal goes beyond a quick visual estimate. It provides a documented evaluation based on gemological examination, market research, and the appropriate valuation methodology.
