Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations,
19、governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further mai

23、 EN ISO 18323:2015ISO 18323:2015(E)IntroductionA diamond is a mineral; it forms and grows under natural geological processes.The jewellery industry relies upon product integrity and transparency for consumers to have confidence in the products that they are buying. Consumers will not always have the
24、 technical expertise to understand the exact provenance and processing of a diamond and as a result, are reliant upon labelling and product descriptions as well as guidance from the individual seller.The recent development of new technologies in the diamond industry has provided consumers with great
25、er availability of synthetic diamonds which are produced in a factory or laboratory (see 2.4 NOTE 3). They have essentially the same chemical composition and physical (including optical) properties as a diamond and essentially the same crystal structure but due to the growth environment, differences
26、 in the growth structure take place at the atomic level.A major concern held by the diamond industry is that without clear and accurate labelling, the increased availability of synthetic diamonds to consumers can cause confusion over exactly what type of product is being sold to them. While the prov
27、enance and labelling of a diamond is widely understood, the consumer will be less familiar with the variety of terms that have been used by sellers to describe synthetic diamonds.The diamond industry is concerned that a consumer can inadvertently buy a synthetic diamond or other product believing it
28、 to be a diamond and similarly, the synthetic-diamond industry does not want its products to be seen as a cheap alternative to a diamond or as a product that consumers will only buy if they are not fully aware of its provenance.Considering that synthetic diamonds are nowadays set in jewellery pieces
29、 it is therefore in the interests of both sectors of the market that consumers are able to make informed purchasing decisions.This document is specifically designed to be understood by the consumer and seeks to address the potential for confusion by setting out clear and accurate guidelines on accep
30、ted nomenclature.The Standard is based largely on existing industry self-regulation documents and labelling that provide voluntary guidance for the industry on how to describe diamonds, treated diamonds, synthetic diamonds, composite diamonds and imitations of diamonds.The following definitions appl
31、y in understanding how to implement an ISO International Standard and other normative ISO deliverables (TS, PAS, IWA). “shall” indicates a requirement; “should” indicates a recommendation; “may” is used to indicate that something is permitted; “can” is used to indicate that something is possible, fo
32、r example, that an organization or individual is able to do something.ISO/IEC Directives, Part 2 (sixth edition, 2011), 3.3.1, defines a requirement as an “expression in the content of a document conveying criteria to be fulfilled if compliance with the document is to be claimed and from which no de
33、viation is permitted.”ISO/IEC Directives, Part 2 (sixth edition, 2011), 3.3.2, defines a recommendation as an “expression in the content of a document conveying that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others, or that a certain cou
34、rse of action is preferred but not necessarily required, or that (in the negative form) a certain possibility or course of action is deprecated but not prohibited.” ISO 2015 All rights reserved vBS EN ISO 18323:2015ISO 18323:2015(E)BS EN ISO 18323:2015Jewellery Consumer confidence in the diamond ind
35、ustry1 ScopeThis International Standard specifies a set of permitted descriptors for the diamond industry and is specifically designed to be understood by the consumer. The Standard also includes a series of definitions which aim to provide further clarity for traders and maintain consumer confidenc
36、e in the diamond industry as a whole.This International Standard will cover the nomenclature to be used by those involved in the buying and selling of diamonds, treated diamonds, synthetic diamonds, composite diamonds and imitations of diamonds.2 Terms and definitionsFor the purposes of this documen
37、t, the following terms and definitions apply.2.1naturalformed completely by nature without human intervention during the formation2.2diamondmineral consisting essentially of carbon crystallised in the isometric (cubic) crystal system, with a hardness on the Mohs scale of 10, a specific gravity of ap
38、proximately 3,52 and a refractive index of approximately 2,42, created by natureNote 1 to entry: The denomination “diamond” without further specification always implies “natural diamond”. These two terms are equivalent and carry the same meaning.2.3treated diamonddiamond (2.2) having undergone any h
39、uman intervention other than cutting, polishing, cleaning and setting, to permanently or non-permanently change its appearanceEXAMPLES Coating, fracture filling, heating, irradiation, laser drilling, HPHT treatment or any other physical or chemical process2.4synthetic diamondlaboratory-grown diamond
40、laboratory-created diamondartificial product that has essentially the same chemical composition, crystal structure and physical (including optical) properties as a diamondNote 1 to entry: The English terms laboratory-created diamond or laboratory-grown diamond may be used synonymously with synthetic
41、 diamond. Where there is no acceptable local direct translation of the English terms laboratory grown diamond or laboratory created diamond then only the translation of the term synthetic diamond should be used.Note 2 to entry: Abbreviations such as lab grown, lab created “lab diamond” or syn diamon
42、d shall not be used.Note 3 to entry: The word “laboratory” refers to the facility which produces the synthetic diamonds. This should not to be confused with a gemmological laboratory that is dedicated to the analysis, authentication, identification, classification (grading) of diamonds.INTERNATIONAL
