Diamond Guide

You’ve found your 1/1, the singular person you want to share your life with. Finding the perfect engagement ring shouldn’t be so daunting. Here’s a primer.



Center Diamond

The center diamond accounts for the majority of a rings value. Eighty-three percent of all engagement rings have a diamond center stone.

Noble Metals

Durable noble metals such as gold or platinum are ideal for protecting your center stone from daily wear. At O.C. Tanner Jewelers, our proprietary white gold uses palladium, which renders the metal hypoallergenic, heightens the pure white color and improves long-term durability.

Carat Weight

The unit of measure used for the weight of a diamond is the carat. Carat weight can also be divided further by using points, and there are 100 points in one carat. For example, a half (.50) carat stone can also be expressed as 50 points.
