Treatment
- In some types of alternative medicine, stones are placed on the body at points of discomfort or on \"spiritual centers\" known as \"chakras.\" Some people report relief from these treatments, although traditional medical research has not proven that any cure or healing occurs beyond a placebo effect. The treatments themselves are usually not harmful. However, some people use t…
Causes
- Dying is possible because many tumbled stone materials are porous. This allows colored dye solutions to enter the stone and impart a bright color. Brightly colored stones are often easier to sell and many people like them. Dye is usually used on light-colored, inexpensive, noncommercial stones that can be tumbled in a short amount of time. These include: magnesite, diorite, granite…
Effects
- Dyed stones are often not colorfast. Some will lose their color with prolonged exposure to sunlight. Water-soluble dyes can transfer from a stone into water or onto hands, clothes, or other objects. Dyed stones usually fade if they are placed outdoors in exposed locations. Vendors who sell dyed stones should inform buyers to prevent disappointment.
Appearance
- Some light-colored agates will turn brown or orange with heating, or black if they are first soaked in a sugar solution. These are sometimes sold as \"carnelian,\" \"onyx,\" or \"black chalcedony.\" These heat treatments are permanent, but buyers should be informed because the \"commercial identity\" of the stone has changed.
Formation
- The heating process can also occur naturally. Agate, tiger's-eye, and amethyst are materials that sometimes form in volcanic landscapes. They can be heated if the rock units that contain them are overrun by a lava flow or if a magma body intrudes above or below. The altered identity of these stones is considered to be \"natural.\"
Definitions
- The word \"polished\" can be used in multiple ways. One definition would be: \"something has been done to make the surface of a stone smooth and shiny.\" Another definition would be: \"something has been done to make the surface of a stone look smooth and shiny.\" Both of these would likely satisfy a dictionary definition of the word \"polished.\" But there is a subtle differenc…
