We Are Always Buying
When you are ready to sell your diamond ring, unwanted jewelry, fine watches, sterling silver, estate jewelry, coins or other gemstones and precious metals items, we will make a competitive offer.
Our buyers are experts in valuing diamonds with GIA certificates, or certificates from IGI, AGS, HRD or EGL. No certificate? No problem – we will grade the diamond according to Gemological Institute of America standards. We have several GIA Diamond Graduate gemologists on staff.
Have you checked the value of your Swiss watch? If you want an offer for your Rolex, Patek, Omega, Breitling, Panerai, JLC or other fine watch, please bring it in to one of our locations.
