Our Quality

Find out what makes us special.

What makes Simon G. special lies not only in its stunning designs, but also in the careful attention to the detail. Just like any relationship, it’s all the little things that add up to the big picture. When it comes to quality, we spare no expense. Our jewelry is built to last a lifetime and beyond.

Diamond Quality

Every piece we create features only top-quality diamonds with GH or higher color and SI or higher clarity.
Additionally, many in the industry use glue to set the diamonds or set them using only two prongs. We go a step further and use four prongs to protect diamonds and prevent stones from falling out.


Simon G. platinum is alloyed with iridium, which prevents the development of a gunmetal color appearing over time.




Simon G. 18K white gold is alloyed with palladium to ensure that the jewelry retains a crisp white color and requires less rhodium plating over time. Most 18k white gold on the market contains 5-8% nickel, but Simon G.’s white gold only contains trace amounts of this metal which reduces the risk of allergic reaction.


Conflict Free Diamonds

We believe a piece of fine jewelry should play an important part in the story of the people who give and receive it. It’s just one of the reasons why we care about the story of every diamond used in every piece we create, and it’s why each is 100 percent conflict free.
