Diamonds at Mountz

Every single diamond that comes through our doors is thoroughly inspected by our certified gemologists. That way, we make certain that our customers receive a premier quality that’s second-to-none. During this process, we also reject diamonds that don’t meet our standards. This number ends up being a lot higher than the diamonds that are accepted by our team. Even after this rigorous analysis, Mountz Jewelers carries the largest selection of diamonds in central Pennsylvania. When you walk through our doors, you’ll have confidence knowing that you’re receiving the best-of-the-best.

The 4 C’s

Diamonds are the most valuable of all gemstones because of their rarity. Not all diamonds are equal so the Gemological Institute of America created a diamond grading system to objectively evaluate diamonds based on the four C's: Carat, Color, Clarity, and Cut.
