More round diamonds touch the split shank for a total diamond weight of 1/8 carat. This is a delicate stone and is ranked a 5 on the mohs scale. The hardness of this stone is comparable to that of an opal; treat it like the exotic gemstone that it is. Proper care of this stone is highly important. Do not clean in an ultrasonic cleaner. Clean with mild soap, warm water and soft bristle brush, store in dry environment out of direct sunlight. Rings should be kept in padded jewelry box. Sterling silver should be kept in a tarnish free bag or box.
