Why Choose a 3 Carat Vintage Engagement Ring?

3 carat diamond vintage engagement rings are a popular choice for those with a cultivated taste for fine jewelry. One of the strongest advantages of the three carat range is its size. A three carat diamond is large enough to be dominant and bold, but not too big to be flashy or get in the way. Since the supply of 3 carat diamonds is very limited and there aren’t many companies that collect them, customers tend to gravitate towards the few collectors that have them in their collection.

Please note that not all of our 3 carat rings are posted on our website. Please contact us below if you are looking for a specific size or color diamond ring.

How much does a 3 carat diamond cost?
