How to Set a Diamond in a Semi Mount
In a semi mount setting, the side stones and accents are in place, but the center, focal gemstone is missing. This allows the consumer to customize the piece of jewelry by choosing a diamond. You can create your own semi mount jewelry at home, using loose gemstones and tools purchased at jewelry supply stores.

Open your gem setting pliers and place the jaws around the prongs. Rest one jaw on the prong to be tightened and the other on the opposing prong. Using gentle pressure and being careful not to let the pliers slip, close the prong, pressing it against the diamond. Turn your pliers and repeat on the opposing prong. Continue tightening opposing pairs of prongs instead of simply moving around the stone.

4
Test the stone to make sure it is secure within the prongs. Use a prong pusher for tightening, applying pressure to the prong from the base towards the stone.

5
Use a jeweler's file to carefully remove any scratches left on the prongs from the pliers.

Tips & Warnings
Practice your technique on a less expensive setting and stone before setting your diamond.
The more prongs in your setting, the more secure your stone.
