Internationalization of the jewelry sector

Many centuries ago, the jewelry industry began. Not only has jewelry making evolved into a global and lucrative industry, but it has also become a form of art and a cultural legacy that spans many eras and cultures. Unlike other types of activity, jewelry making is distinguished by its stability and low volatility. Today, export-import trade is closely entwined with the production of jewelry on a global scale. Due to the fact that each nation has its own unique policy for regulating the supply of precious metals, there is a need for international regulation of the jewelry industry to harmonize technological parameters and quality standards. International standardization is one such regulation option.

Screening for the presence of nickel in objects intended for piercings and objects that will have direct and prolonged skin contact

SIST-TP CEN/TR 12471:2022,

Since no piece of jewelry is ever made entirely of one metal, certain impurities can have an impact on both the pricing structure and the likelihood of specific skin reactions. International standards like SIST-TP CEN / TR 12471:2022 were developed in order to regulate and control the amount of impurities of certain elements found in jewelry, such as nickel.

This document describes a screening test based on the use of dimethylglyoxime to identify nickel release from objects that are inserted into pierced areas of the body and objects intended to come into direct and prolonged contact with skin.

The screening test can be used by importers and manufacturers as a qualitative method of inspecting products for nickel release.

NOTE EN 1811 or EN 16128 are the reference methods for measuring nickel release in eyeglass and sunglass frames, respectively.

We strongly advise that this document be used in conjunction with other documents of a similar category since it only describes one of the potential methods for determining the presence of nickel in a piece of jewelry. You can always ask our expert for advice if you need specific details on this document clarified.

Jewelry - Determining the amount of platinum in platinum jewelry alloys using a gravimetric method following diammonium hexachloroplatinate precipitation (ISO 11210:2014)

SIST EN ISO 11210:2016

It is important to know what proportion of each metal will be present in the finished jewelry when making precious metal jewelry. These calculations are required primarily to comprehend the physical properties of the product, which will have an impact on human health when worn, rather than to determine the cost and final price. The use of international standards like SIST EN ISO 11210:2016 is crucial when it comes to platinum jewelry.

The gravimetric method described in ISO 11210:2014, which is preferably within the fineness range specified in ISO 9202, can be used to determine the amount of platinum in platinum jewelry alloys.

Palladium, iridium, rhodium, copper, cobalt, gold, ruthenium, gallium, chromium, indium, and tungsten at a maximum of 5% can all be found in these alloys. When gold, ruthenium, iridium, palladium, or another metal is present, some modifications are indicated.

A product's quality and profitability when it enters more international markets can be greatly improved by properly implementing an international standard. Because of this, we advise that if you want your business to grow consistently, you should always be aware of and adhere to international standards.

Sampling of precious metals and precious metal alloys used in jewelry

ISO 11596:2021

Finding a high-quality item that is actually made from precious metals can be very challenging because there are so many products and metals available. Because of this, a lot of companies are trying to figure out how to verify the quality of their purchases while preserving their good name. The acquisition of international standards, such as ISO 11596:2021, that provide a thorough explanation of the methodology for determining the ratio of metals is one of the verification options.

This document describes a technique for sampling precious metals and precious metal alloys in order to gauge their homogeneity and gauge their precious metal content.

The document, which is applicable to raw materials, semi-finished goods, and finished goods, is only to be used for the sampling of materials that are entirely metallic in nature.

NOTE 1 The Bibliography contains a list of standards for determining the amount of precious metals in various metals.

NOTE 2 Additional sampling techniques may be needed for assaying methods not listed.

NOTE 3 For the purposes of production control or lot inspections, the International Standards for the Sampling listed in the Bibliography or corresponding guidelines may also be used.

If you or your business produces and sells jewelry, this international agreement will greatly assist in defending you against the presence of subpar goods and, as a result, defend you from issues with your brand's reputation in the marketplace.

Gold determination in jewelry and precious metals using the Cupellation method (fire assay) is outlined in ISO 11426:2021

SIST EN ISO 11426:2021,

Despite the simplicity of semantic perception, there are many different ways to define the concept of gold in a technical setting. Since quality is the only consideration when paying for a good or service, the consumer is not concerned with these technical details. Manufacturers must realize, though, that adhering to global norms and regulations, as outlined in international standards like SIST EN ISO 11426:2021, is the only way to guarantee quality.

This document describes a cupellation method (fire assay) for detecting gold in a material that is thought to be homogeneous.

The sample's gold content should be between 100 and 999.9 points out of 1,000 (ppt)by weight, preferably. A spectroscopy method by difference (e.g. g. ISO 15093).

Most types of gold samples can be processed using this method. For particular situations (the presence of a significant amount of base metals, platinum or palladium, or silver), some modifications are suggested. The presence of iridium, rhodium, and ruthenium at levels above trace levels (more than 0 point 25 for the sum of the three elements) is incompatible.

Additionally, this technique is meant to be used as the suggested technique for figuring out the fineness of jewelry alloys covered by ISO 9202.

Thus, by putting the advice given in this document into practice, it will be much clearer in production what technical and chemical characteristics gold has that should be used to create high-quality goods that consumers will be interested in.

Jewelry and international standards

A significant amount of jewelry currently exists that is made up of a variety of alloys and metals. As a result, in order to strengthen the company's position in a market that is fairly competitive on a global scale, it is essential to enhance quality indicators and have a set of available global standards. Since gold has a positive economic impact, this industry is currently growing more and more actively and will continue to do so. With the emergence of digitalization and information technology, medium-sized and large-sized businesses are growing at an exponential rate. As a result, it is important to recognize that the only thing that can give you a significant competitive advantage is access to reliable information about the standards and laws that govern your industry and the market in which you operate, as well as the ongoing monitoring of any changes to these laws.
