Ensure Your Jewelry Is Protected, Valued, and Properly Documented

Fine jewelry is more than a luxury — it's an investment, a symbol of love, and a part of your personal legacy. Whether you own a diamond engagement ring, antique heirloom, or designer piece, knowing its true value is essential.

At Joseph Gann Jewelers in Boston, our professional jewelry appraisal services provide you with accurate, certified documentation to protect your treasures and preserve their value.

What Is a Jewelry Appraisal and Why It Matters

A jewelry appraisal is an official evaluation of your item's current market or replacement value, conducted by a certified expert. Each appraisal includes a thorough analysis of your jewelry's materials, gemstones, craftsmanship, and condition.


You may need an appraisal for:


  • Insurance purposes – to ensure proper coverage in case of loss or theft
  • Estate planning or inheritance – for accurate valuation and asset documentation
  • Resale or trade-in – to determine fair market value
  • Peace of mind – simply to know the worth of your cherished items
