  • WHILE YOU WAIT SERVICE: You never have to leave your jewelry. An appointment is required for while you wait services.
  • DROP OFF SERVICE: No appointment is necessary. We will schedule to return the items in a timely fashion. You will receive a complete itemized list of the items you leave. For your confidence and piece of mind your items will be secured and locked in a safe with 24 hr. security.
  • MAINTAIN DOCUMENTATION: In addition to your formal appraisal we maintain all information in our database for up to ten years. This will be helpful should you loose your information, need an update.
  • YOUR APPRAISAL PAPERS: We will produce one original report and supply you with a full set of copies. The report takes approximately one week to complete from the day we finish retrieving the information for the appraisal.

When you bring your items of jewelry to our lab, we will perform the following procedures:

  • Mounted stones: are measured and an estimated weight is given. They are not removed from the mounting.
  • Loose stones are weighed.
  • Diamonds: grade stones for color, clarity and cutting. Stones that are 0.50 or more we plot inclusions in order to re-identify in future (finger-printing).
  • Colored stones: Color description, estimated weight. On larger stones we do a Gem Identification to determine the physical properties of the stone and whether it is natural or synthetic and if treated when possible.
  • Acid testing on mountings to determine fineness of gold or platinum only when needed or if the marking are questionable.
  • Determine value (retail replacement, wholesale, liquidation, estate, tax purposes, etc.)
  • Color digital photographs for identification
  • Explain anything pertaining to the item that a client might not understand.
