This is an earring finding made of K18 (5:5) gold, with the part that goes in the ear soldered on. It is for 5mm stones. The images from the third to the sixth are sample images of when 5mm cubic zirconia stones are set. The size of the 5mm cubic zirconia used in the sample is: Outer diameter: 5mm Height: 3.12mm Please consider whether or not the stones can be set by comparing them to the size of the stones that can be set in the setting. To set the stone, place the stone and push the setting down from above, as shown in the fourth photo. The stone can be set like this, but if there is a gap at the bottom, it may come loose. Therefore, if you push it down to the bottom as in the fifth photo, the prongs of the setting will open slightly and touch the bottom. After that, you should be able to set the stone by carefully bending the prongs of the setting diagonally at the same time. I use stainless steel tweezers. The weight of the setting is about 0.2 grams per pair, and about 0.6 grams for 3 pairs (6 pieces). There is a K18 stamp.
