Precious Gemstones

Any gemstones that is not a diamond, ruby, emerald or sapphire is a semi-precious gemstone. Calling a gemstone semi-precious does not mean it is less valuable than precious gemstones. ... Some semi-precious gemstones are not stones at all, but are made of organic material like amber, coral and pearl.

Raw Material Used : A gemstone (also called a gem, fine gem, jewel, precious stone, or semi-precious stone) is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments.

Industries where this product is used : Jewelry

Colors & packaging available : The color of any material is due to the nature of light itself. Daylight, often called white light, is actually all of the colors of the spectrum combined. When light strikes a material, most of the light is absorbed while a smaller amount of a particular frequency or wavelength is reflected. The part that is reflected reaches the eye as the perceived color. A ruby appears red because it absorbs all the other colors of white light (green and blue), while reflecting the red.
