Similar definitions are also given in ISO Standard 18323.Members of CIBJO, the World Jewellery Confederation, are national jewellery associations of more than 40 different countries, over 60 commercial members from 18 countries and 8 governmental institutions. CIBJO’s primary mission is the protection of consumer confidence in the jewellery industry. The definition of a diamond A diamond is a mineral consisting essentially of carbon that crystallises in the isometric (cubic) crystal system.A mineral is natural by definition. The definition of natural materials Materials that are completely formed by nature, without human intervention during its formation.Thus, unambiguously a ‘diamond’ is a natural material and the unqualified term ‘diamond’ can only designate a diamond of natural origin. The definition of a synthetic diamond/ laboratory-grown diamond* Artificial product having essentially the same chemical composition, physical properties, and structure as that of a diamond, whichever method of growing is used.The terms ‘synthetic diamond’, ‘laboratory-created diamond’, and ‘laboratory-grown diamond*’ are synonymous.* While CIBJO does not endorse this abbreviation, ‘LGD’ is sometimes used in the trade. The definition of an artificial product A product which is partially or completely made by man.
