The Crystal Bible. Krause Publications. (Note: I make no claims on whether or not Agate can help with the things mentioned.) Note: All pearls/stones may slightly vary in color, shape, and size because they are real/natural pearls/gemstones. Some pearls/stones may have been dyed or heated to enhance their color. I do my best to match all pearls/stones for color, pattern, shape and size. All pictures are taken in natural light. Colors may vary slightly when viewed on different screens/devices.
