It delivers awesome brilliant rainbows. This is one of the classic cuts which is a must for any rainbow-lover. The angles of this cut capture the sunlight at any possible angle, so when some of the other prisms have petered out, this one keeps throwing those rainbows, even when the sun is high in the sky. The exquisite cut cone prism at the bottom delivers dozens of pinpoint rainbows everywhere. The Heart is the perfect gift.

The spiraling symmetry of this prism makes this a very dynamic addition to your collection. Not easily seen here, each diagonal facet is set at a slight angle from the next, so its shape gently spirals instead of remaining flat. It employs three different manners of light refraction.
