Learn about our Good, Better, Best model


I would highly recommend MJ Gabel to anyone searching for the best way to sell an unwanted diamond ring…Ultimately I got back about 2/3 of the cost I’d spent on the ring 6 years ago– far better than I expected or likely could have gotten from other sources...I can’t recommend MJ Gabel highly enough. Anne made the process as transparent, easy, and pleasant as possible, and I got more than I expected for the ring… Jimmy B. SC
