Signet rings can be made with a wide variety of stones. The most common stones are shown below.
In the past years we have noticed that the ladies rather prefer different stones than the traditional blue layered ones. We regularly make ladies rings with an Almandine (Garnet), Sapphire (blue and yellow), Topaz (blue), Aquamarine, Smokey Quartz, Tourmaline and Citrine. These stones are especially cut to be engraved. However these translucent stones are vulnerable in comparison to the untransparent stones.
