Eighty percent of all diamonds mined are used as industrial diamonds, to improve the cutting and precision of industrial tools.
Natural diamonds can be industrial diamonds or gemstone quality diamonds. Gemstone quality diamonds are worth more than industrial diamonds. If by 'industrial', you mean man-made, then a natural diamond will always be more valuable than a man-made diamond of equal carat weight, unless the natural diamond is not of gemstone quality.
Insofar as gems are concerned, there are several semi-precious and outright fake objects that can be 'alternatives' to a diamond. Quartz, white sapphire, zircon, moissanite, and glass. Insofar as industrial use for diamonds -- about 80% of all diamonds mined are industrial diamonds, there are no natural substitutes. However, there are man-made, lab-created alternatives: man-made diamonds.
Generally speaking, manufactured diamonds have the same chemical and physical properties of diamonds which are dug from the earth. So, yes, they are real. A certified gemologist will be able to discern a manufactured diamond, and will document it as such. Its value is considerably less than a natural diamond of similar characteristics. Manufactured diamonds are not natural diamonds. There are other man-made gemsones which are presented as diamond substitutes. Those are not real diamonds either.
Yes, a raw gem-quality diamond is a clear stone which may have a colour cast, and also may appear to be a pyramid shape or two pyramids joined at the base if you find one in its perfect natural shape. Industrial diamonds however are not clear and represent about 80% of all diamonds mined. There is no standard shape, size, colour or clarity for an industrial diamond. Diamonds are formed from carbon.
Industrial diamonds come from diamond mines, in fact about 75% of all diamonds mined are industrial diamonds.
Industrial diamonds are formed at the same time and in the same places as gem-quality diamonds. Industrial diamonds represent about 80% of all diamonds mined.
You may be thinking of gem-quality and industrial diamonds. About 80% of all diamonds mined are industrial diamonds.
You may be thinking of gemstones and industrial diamonds. Gemstones represent about 20% of all diamonds mined, and the remainder is industrial diamonds.
These diamonds are industrial diamonds. About 80% of all diamonds mined are classified as industrial diamonds, leaving only about 20% to be graded as gemstones.
Raw diamonds are found in the earth; cut and polished diamonds are available in jewelery stores; industrial diamonds can be purchased from an industrial diamond broker.
The most common use of diamonds is for industrial tools, because industrial diamonds are the most common diamonds.
Industrial diamonds can appear cloudy and gray, because of their flaws and inclusions.
Yes, most diamonds mined -- about 80% -- are industrial diamonds that are only used in tools. Industrial diamonds improve precision, durability, and use.
About 75% of all diamonds mined are used for industrial purposes: they are not gemstone quality.
Diamonds from any source are used about 75% of the time for industrial purposes.
Most industrial diamonds and other gems are called synthetic
