Why Settle For Less


Many consumers are unaware that more than 95% of jewelry stores are NOT qualified to do jewelry appraisal work, lacking the education, expertise, and instruments to do a proper and accurate jewelry appraisal.  In addition, there is an inherent conflict of interest caused by the fact that many times they are selling the same item in their store.  This can be a problem when getting a jewelry appraisal on a brand new piece of jewelry to have it "checked out".  The jeweler may be tempted to "lowball" the value of your piece in his jewelry appraisal so that they can then convince you to return your jewelry so that they may sell you their own .

Mark Reyman would like to answer any questions you may have about having your diamonds, jewelry, antique jewelry, and watches appraised. 

Please call 914-574-4480 and talk to one of our gem experts today.


"Did I get a good deal..."


"I just bought a new piece of jewelry and I want to have it "checked out"."

  "Did I pay too much?"

  "Is it good quality?"


"I just got engaged... "


The next step is to get an engagement ring appraisal so that I can insure it.


"I'm curious about its real quality (not the quality the seller told me it was)."


"I'm thinking about selling my diamond / jewelry"


"I want a professional jewelry appraisers opinion of its value"


"How much do you think I can sell it for?"
