Factory Diamonds

"Whether for diamonds, sapphires, rubies or emeralds, Rolex masters the art of gem-setting. ~Rolex

The easiest sign of a Rolex set gemstone is in the alignment. Each diamond's table is aligned perfectly with the center of the dial. Each diamond or gem table should be aligned in a uniform direction.

Aftermarket Diamonds

Aftermarket diamond accessories can have cracked, cloudy or non-white stone. Study the cut quality of each stone. If it's not perfect it's not Rolex.

Aftermarket dials have been repainted and applied. This means the "ROLEX" print is not authentic and is not applied by the manufacturer.

With the art and craft of a jeweller, the stone is placed and meticulously aligned with the others, then firmly secured in its gold or platinum setting.

What should be considered when purchasing aftermarket diamonds?

As popular as an aftermarket diamond set Rolex watches are, they fail to hold their value as well as a factory diamond Rolex.


Often times the quality of work is vastly lower than Rolex’s strict standards. Many times the added diamonds can detract from the resale of the watch.


If you’re looking for a Rolex to hold value, do not add low quality aftermarket diamonds to the case/bracelet/bezel/dial as it damages the elements of a watch that were not designed for the setting. 


The setting process is costly and will not translate to a higher resale amount. Factory diamonds retain value far better due to their high level of workmanship and high quality look.


If you purchase an aftermarket diamond Rolex, you run the risk of the setter damaging the watch in ways that allow moisture to penetrate the case. Beware of low quality settings.


Loupe your purchase and study the level of workmanship. Everything is cheap for a reason.
