Below are some photos of diamond set rings that I have made.

Each style suits different tastes, budget and trends.

Flush set rings are usually less expensive to make, although some square settings are more expensive.
Grain set and Channel set rings involve more preparation and usually have a higher diamond weight.
Claw set rings, in the case of eternity rings and some wedding bands are complicated little items. This technique is employed when you want to get the most out of your diamonds.
