The setting looks similar to a tension setting but has a small metal bridge connecting the 2 ring sides underneath the gem stone. The bridge is invisible from the top. It is more secure than a typical tension setting as it does not rely on the springiness of the metal alone to hold the moissanite. It also allows for resizing in the future (about one size up or down). The setting holds the gemstone securely while allowing lots of light to enter from the sides.
