Though it looks somewhat similar to Spiderweb Jasper, upon closer inspection there are slight differences in appearance. While Spiderweb has lines appearing similar to actual spiderwebs, Pinolith look more like actual cracks of black lines on the stone. Pinolith is a gemstone believed to be useful for optimism and balance and can provide a soothing, calming effect. This can in turn improve self-esteem all the while establishing equilibrium between emotions and intellect.
