Client Testomonials

I was very pleased with your professionalism and quality of the appraisal.  But what stood out to me the most was the phone call I received from you the day after I received my appraisal.  Thanks for taking the extra time to answer my questions.  I am more than happy to take this moment to write this testimonial for you as the service that was provided to me far exceeded my expectations.

- Tom McHugh,

Thanks a bunch for the timely appraisals.  Just wanted to let you know that we were able to send the appraisals with the shipment of goods in time to our client, and he was very happy.  You were very reliable during our time crunch, and I know we wouldn’t have made the deadline without you.

- Leslie Stadham,

I can’t thank you enough for your help. Because of your appraisal I was able to get back my money from the store in Alaska that I purchased the necklace from. Really scary to think that if I hadn’t actually got my piece appraised I would be walking about town with a fake.

What kind of Appraisal Services do we offer?

There are two basic types of appraisals.

1. Insurance appraisal is used to determine the retail replacement cost for insurance scheduling. The value that is given to your piece is the price upon which your premium is set. A detailed description is crucial in order to replace the piece if necessary with an item of equal quality and kind. Because of this, it is very important that the descriptions be extremely detailed and specific.

2. Fair Market Value appraisals can be used for a variety of purposes, including cash liquidation, collateral, divorce settlement, investment, estate probate, and charitable contributions.
In order to determine which type of appraisal is right for you, it is crucial to tell your appraiser what you intend to do with the piece, or the reason why you are looking to have it appraised.

Our appraisals include the following information but are not limited to:

  • A detailed description of the item
  • Metal content and weight (14K white gold, 18k yellow gold, platinum, etc.)
  • Measurements (length, width, thickness)
  • Metal finishes (polished, matte, sand blasted, etc.)
  • Settings (six prong set, bezel set, channel set, etc.)
  • Manufacturing technique (custom wax and cast, die struck, cast and assembled, hand fabricated, etc.)
  • Type of findings (spring ring, lobster claw, barrel, etc.)
  • Condition of the piece (new, excellent, fair, etc.)
  • Design (custom, serpentine, curb link, etc.)
  • Engraving (if applicable)
  • Circa (the age of the item)
  • Style number (if applicable)
  • Signatures, hallmarks, and trademarks (if applicable)
