The CVD organization does not appear to be in the business of producing gem-quality diamonds. You can review their products, below.
Overall quality of life
Industrial quality diamonds are used to make tools more precise, longer lasting and useful overall, because diamond is the hardest natural mineral on Earth.
The highest quality diamonds are found in the earth.
Only 25% of diamonds mined are gem quality: the remaining 75% are industrial diamonds, which is another term you could use for low quality diamonds.
The management of quality keeping at par the cost of the organization involved is referred to as the economics of quality. It is associated with the appraisal of the product quality and at the same time ensuring maximum return for the concerned organization. The earlier concept of 'economics of quality' strived towards assuring a minimum level of quality which resulted in reduced investment and thereby increasing profitability. However the modern concept of 'economics of quality' focuses at attaining an optimum level of quality with the available resources and funds and thereby increasing the overall profitability of the organization. The process of 'Economics of Quality' involves identification of quality affecting parameters and regulating them a manner to achieve an optimum level of quality at which the overall profitability of the organization is maximized.
Brown diamonds are the most common colour of diamonds mined, of gem-quality. Only about 20% of all diamonds mined are of gem quality.
Diamonds are classified as industrial -- about 80% -- and gemstone quality, the remainder. Gemstone quality diamonds are classified according to cut, clarity, colour and carat weight.
Not all diamonds have high quality. There are people who sell terribly included diamonds and attempt to pass them off as 'high-quality', which they are not. As well, most diamonds mined today are used for industrial applications and not for jewelry. Industrial-quality diamonds are not high-quality material. A certified gemologist will help you document exactly how the high the quality is in a diamond that you present for certification.
'Low quality' diamonds are industrial diamonds, which make up about 80% of all diamonds mined. 'Low quality' diamonds used in jewelery could be cloudy with visible inclusions or could be poorly cut.
About 20% of all diamonds mined are gem-quality diamonds.
Diamonds come in all sizes: 20% of which are gem-stone quality, the remainder are industrial diamonds. Most diamonds are tiny: gem-stone quality diamonds must be larger than most diamonds found, because of their use. Gem-quality diamonds must be visible, which is not true for industrial diamonds. Your answer, then, by logic, dictates that most diamonds an average diamond is much smaller than a pea.
