Our passion for precision-cut diamonds leads us to extraordinary measures to source the finest cut diamonds in the world today. The result are diamonds with a lifetime of dazzling non-stop brilliance.

With the purchase of a Cross diamond ring comes an insurance appraisal attesting to its quality as well as an independant laboratory certificate (.80ct and larger) from one of the world’s two most respected gemological testing facilities (GIA or AGS).

Cross guarantees the diamond to be 100% natural and the diamond grade to be accurate.


Cross Quality Diamond Setting


How well a diamond is set and secured is often overlooked by engagement ring shoppers. The quality of setting is not obvious at frist glance, and can really only be seen under a microscope.

The quality of the diamond setting plays an essential role in the safety, security, and enjoyment of a ring for decades. How well a diamond is set can mean the difference between a ring that spends a month a year in a repair shop to tighten/re-secure, a ring that keeps snagging on fabrics, or even a lost gem, versus a ring that can be worn and enjoyed for years with minimal upkeep.

All center diamonds at Cross are set by one of Cross’s own jewelers. The Cross standard for diamond setting has remained the same for over 100 years. The reason is simple: there is just one right way to set a diamond securely in a prong-set ring.

  • A prong should have an angle cut into it which provides a secure seat on which the diamond evenly rests.
  • The prong should be drawn securely down over the top edge of the diamond to rest flat and secure over the surface of the gem.
  • The heel of the prong should be thick enough to provide structural strength for years of wear.
  • The prong should have a smooth, rounding polished surface.

All the above factors are important because when a diamond is set properly it looks its best and is as safe as it can possibly be.

We do recommend a professional clean and check for all jewelry at least once per year. Clean and check is always free at Cross and takes just a few minutes.

What to Avoid
in Poorly-Set Jewelry

We see poorly set gems every day from jewelry that is brought in for cleaning or repair. Shown below are common examples of improperly set diamonds.


The Cross Craftsmanship Difference

Our diamond setters are instructed to take the full measure of time to ensure each job is properly completed. When setting a diamond they work with a 20x power microscope because working under this level of magnification means the finished ring is the most beautiful and secure it can possible be.
