Jewelry Appraisals

We offer in-house jewelry appraisals and trade estimates on jewelry.

Retail appraisals are an important accompaniment to fine jewelry purchases. At Rockstoc, our team has over 50 years of combined experience in appraising and assessing fine gemstones and jewelry. Diane brings decades of technical experience to the table, while Yvonne contributes the knowledge she has acquired from buying direct at gemstone mines all over the world. Together, their combined expertise provides peace of mind that the value of your piece correlates with its purchase price, while allowing you to insure your precious jewels for their full replacement value. Factors such as current gemstone and precious metal prices, quality of workmanship, and well-known manufacturers or designers are carefully assessed to determine the final estimated value of each piece of fine jewelry submitted.

Because the cost of diamonds and precious metals rise over time, it is important to have your jewelry appraisals updated every five years. Appraisals over a decade old may record the value of your fine jewelry as far less than what the piece is worth in today’s market. Our appraisals are efficient, thorough, and reasonably priced – so why wait until an item has been damaged or lost to consider its current value? Submit your pieces to our team today and receive a quick, thorough evaluation that prepares you for worst case scenarios.

For those in the trade, quick estimations of value are also available for wholesalers interested in learning more about a specific piece of fine jewelry.

Our in-house gemologist and appraiser (Diana) will be offering these services via:-

  • Online Appointments (via Zoom)
  • Face to Face (Chicago)

Before you go to your appointment please provide whatever documentation you have available.

  1. Dimensions of the piece
  2. Indication of metal
  3. Estimation of stone sizes and or weights
  4. Any supporting documents (receipts, lab reports)

Trade accounts that need estimation of value are welcome to contact
