Setting a diamond into a ring so that it is properly secure, with the claws evenly finished and the diamond and claws nicely symmetrical, requires a great deal of skill.
There are two main factors to consider when setting a precious stone. The first is that the stone must be very secure inside the grooves of the setting. The second factor is that the light needs to pass through correctly so that the stones can sparkle.
Preparing the claws so that they are ready to accept the diamond is the most important phase in setting a stone. All of the prongs must be cut at the proper angle and at the right level to ensure that the stone will sit level in the setting, allowing the maximum amount of light to enter the stone.
Using setting pliers, you can apply just the right amount of pressure at the correct angle, tightening each claw over the diamond, properly securing the stone into the mount.
Once the diamond has been set, it is important to check each claw to ensure that it won't catch or snag on clothing. Finally, once the diamond is set securely, the ring is ready for it final stage of polishing.
