Onyx tile and moonstone are natural gemstones commonly used in jewelry; both gems are stunning and beautiful, each in its own way. Onyx, a pure black stone that is sometimes marbled with shades of white and gray, is often confused for jet since the two can look very similar. Moonstones, which come in a variety of colors, have a unique iridescent quality. Rainbow moonstones can change colors depending on the light in which they are viewed. Determining if a stone is an onyx or a moonstone can be a tricky process. Instructions as follows: Firstly, look at the shape of the sandstone. Moonstones are most commonly cut into cabochons, which looks like an oval cut in half. The flat back of the moonstone is mounted on jewelry, and the top is smooth and rounded. Moonstones are also commonly cut into a perfect ball or sphere shape. While moonstones are sometimes cut in other shapes such as teardrops, this cut is less common. Jewelry-grade moonstones are never faceted. Secondly, inspect the opaqueness or translucence of the stone, as a moonstone can vary from almost completely opaque to translucent. Regardless of whether a moonstone is opaque or translucent, all moonstones have a shifting quality that makes them unique among peculiar stones. Look at the stone in different light sources, such as by a lamp and then by the window. The opaqueness and translucence of a moonstone will look different in every light. An easy way to tell if the cubic stone you have is fake is to see if it changes in appearance; as fake moonstones will not look different under different lighting. This unique shifting ability of moonstones is called "adularescence." Thirdly, look at the color of the stone. Moonstones come in a range of colors, but they are most commonly found in shades of beige, brown, white, lavender and blue. What makes moonstones unique is their color-changing properties. Just as the transparency of moonstones shifts in different lights due to adularescence, they also shift colors in different lighting. For example, a semi-translucent white moonstone can look white in one light, and beige in another. Fourthly, look for a star on top of the stone. Some moonstones have a star that appears to have six or eight points, a marking unique to moonstones although not all moonstones have the stars. If no star is on top of the stone, it is likely a moonstone. Fifthly, touch the stone with your finger. If it feels the same as room temperature, you may have a plastic imitation rather than a real natural gemstone. Real moonstones feel slightly cool to the touch. Sixthly, touch the stone lightly with your finger. Onyx is frequently confused for jet, which is also a black stone but entirely different. Onyx has a cooler feel than jet because onyx is a stone, while jet is actually black fossilized wood. Seventhly, look at the markings on the stone if any are present. If you see random speckles on a part or on the entire stone, the stone is probably a type of marble or granite, and not onyx, which is a chalcedony quartz. Onyx markings form bands that are either white or gray in color. Eighthly, feel the heft of the stone. Onyx feels fairly solid and heavy, whereas, jet is light. Ninthly, run your finger along the surface of the stone and inspect it closely under a light. The surface texture of onyx is very smooth and fine, like glass. It carries a high luster and polish, unlike jet, which has a slightly greasy surface appearance.
