Prismatic Pearl

Prism (optics)

An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled—elements with only two parallel surfaces are windows, not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular sides. Not all optical prisms are geometric prisms, and not all geometric prisms would count as an optical prism. Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, acrylic and fluorite.

Pearl

A pearl is a hard, shiny object produced within the soft tissue of a living shelled mollusk. Like the shell of a mollusk, a pearl is composed of calcium carbonate in a crystalline form, which is deposited in concentric layers. More commercially valuable pearls are perfectly round and smooth, but many other shapes, known as baroque pearls, can occur. The highest quality of natural pearls have been highly valued as gemstones and objects of beauty for many centuries. In literature, pearls have become a metaphor for something rare, fine, admirable, and valuable.

Pearl (color)

The color pearl is a pale tint of off-white. It is a representation of the average color of a pearl.

pearl

Noun

1. A shelly concretion, usually rounded, and having a brilliant luster, with varying tints, found in the mantle, or between the mantle and shell, of certain bivalve mollusks, especially in the pearl oysters and river mussels, and sometimes in certain univalves. It is usually due to a secretion of shelly substance around some irritating foreign particle. Its substance is the same as nacre, or mother-of-pearl. Round lustrous pearls are used in jewellery.

Verb

1. To set or adorn with pearls, or with mother-of-pearl.
2. To cause to resemble pearls in shape; to make into small round grains.
