Sharing Prongs

Showcasing diamonds using a tight setting

Each prong in a shared-prong setting helps to hold more than one diamond, so the stones can be set tighter together. This technique is a good showcase for diamonds because very little metal shows, making the stones look larger and more brilliant.

You’ll see this setting used mostly with round, oval and cushion-cut diamonds. “These cuts allow pressure to be more evenly dispersed,” says Sandra Johnson, advertising director of Guertin Bros., Roanoke, VA. You won’t see the technique used as often with square diamonds because pressure in one spot can damage them more easily.

When displaying this setting, keep it out of the tray. Show it on a finger or hand. The customer needs to see the sculpted profile.
