6、egarding the term “diamond industry”: In Germany, the term “diamond industry” used throughout this document includes the following professions: rough diamond dealers; diamond cutters; diamond dealers; makers of jewellery and clocks; wholesalers of jewellery and clocks; jewellers; goldsmiths; clockma
7、kers; and all others who deal with diamonds. Note re 2.4: Discussions carried out at European level within CEN/TC 410 led to a compromise regarding the Note to entry 2.4, which was not accepted by Germany. Contrary to the statement given in this document, in the German language, use of the English t
8、erms “laboratory-created diamond” and “laboratory-grown diamond” as synonyms of the English term “synthetic diamond” is not permitted. Therefore, in German, only the term “synthetischer Diamant” (= synthetic diamond) is to be used. EN ISO 1 8323 July 2015ICS 39.060 English Version Jewellery - Consum

22、roductionA 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 technical expertise to understand the
23、 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 greater availability of synthetic diamonds
24、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 in the growth structure take place at
25、 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 provenance and labelling of a diamond is w
26、idely 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 to be a diamond and similarly, the sy
27、nthetic-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 it is therefore in the interests of b
28、oth 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 accepted nomenclature.The Standard is based
29、 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 apply in understanding how to implement an
30、 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, for example, that an organization or ind
31、ividual 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 deviation is permitted.”ISO/IEC Directiv
32、es, 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 course of action is preferred but not nec
33、essarily required, or that (in the negative form) a certain possibility or course of action is deprecated but not prohibited.”4DIN EN ISO 18323:2015-11 EN ISO 18323:2015 (E) 1 ScopeThis International Standard specifies a set of permitted descriptors for the diamond industry and is specifically desig
34、ned 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 confidence in the diamond industry as a whole.This International Standard will cover the nomenclature to be used by those involved in the bu
35、ying and selling of diamonds, treated diamonds, synthetic diamonds, composite diamonds and imitations of diamonds.2 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.2.1naturalformed completely by nature without human intervention during the formation2

37、 further specification always implies “natural diamond”.

Where there is no acceptable local direct translation of the English terms laboratory grown diamond or laboratory created
40、 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 diamond shall not be used.Note 3 to entry: The word “laboratory” refers to the facility which produces the synthetic diamonds. This shoul
