The rings portfolio shows a sampling of custom, one-of-a-kind rings that I have made. There are a couple of reliquary rings shown. The tubes on either side of the center stone hold a small amount of ash or verbouti. Or, perhaps, a flower petal. Ring malas are basically made from two bands. One rotates over the other so that the ring can easily be used as a mala or rosary. You can find out more about ring malas here.
A number of the rings are Vedic in nature, the stones employed in them prescribed by Ayurvedic astrologers.
