Web Links

The wonder of the web offers a gateway to many Internet resources
related to hallmarks via government and national agencies, educational
organizations, private study groups, corporate sites, and private
sites. This page is designed to offer links to the more useful sites
already established as well as promote them by noting their relevance.



  • General Hallmarking Information and Forums

    Hallmarks on the Internet - Janjaap Luijt has done a wonder job on compiling an extensive list of links across the globe dealing with hallmarks. This is our first link as we believe this site should be your first link, too.  Some links in our list here are from this list but repeated here to emphasize their relevance.

    925-1000 Silver Marks and Forum - A great site packed with marks grouped by country. This site offers information on silver marks, and trademarks. The forum features discussions on all tyoes of marks on silver and gold. This is quite an extensive internet resource for researching silver hallmarks & maker's marks. Thousands of images of silver marks and hallmarks.

    Mystery Mark Forum - More like a running dialog on "name that mark" type makers marks and hallmarks than an actual forum.  Definitely worth perusing.

    Silver Forum - An email based forum of knowledgeable individuals on silver, silver designs and maker marks. Very helpful members can help research silver marks and items.

    Silver Magazine - One of the few magazines that we can recommend as being unique and in-depth in its content. Every issue is a jewel of information that continues to amaze us. If you are looking for the Minerva of silver magazines, then this subscription is a must!


    The Jewelry Loupe - Cathy McCarthy interviewed the Directors of HRI in this interview. The resulting blog may answer questions you might have as well.



  • Governmental Assay Offices and Related Sites

    Hallmarking Convention - Keep up on the regulations as they change for Common Control Marks (CCM) used throughout hallmarking countries. The best location for active links to each member country's websites.

    Birmingham Assay Office Mark Search - Birmingham has added a database to their website that allows the public to search their sponsor, duty, and date marks.

    Swiss Federal Customs Office - Scroll down to the 9th video.  It is a very good over view of the fire assay process and the roll hallmarking plays in quality control.

    Finnish Maker Mark Search -Developed in 2009 by the Leimatoimikunta (Mark Commission), who was founded by members of the Finnish precious metal industry, this search engine documents Finnish gold and silversmiths' responsibility marks for the years 1373-1950. Responsibility marks from 1950 to date can be found in the Responsibility Mark Register (nimileimarekisteri) on the Tukes web site.

They offer a good variety of maker's marks here but don't stop just on this page, search through its volumes of information about jewelry and antique jewelry.  This surely will be a new web location you will want to save. 

    Association of Small Collectors of Antique Silver - This is a great site for information on marks and trademarks.  This particular link deals with Tiffany marks on silver.  Click around to see other useful info. An alternate to this site is the ASCAS.  Check both for useful information on silver and their marks.

    Chicago Silver - Don't let the name fool you, here is an online plethora of trademarks. This link will serve as the opening to the 'rabbit hole' of links that will feed your need for searching for a long time! Master List of Links. Remember, just because it says silver, it does not mean your gold maker's mark could not be there too.

    French Maker's Marks - While there is no single source for discovering the identity of the jewelers initials found within the small lozenge shape that is so distinctively a French maker's mark, there are resources scattered about that can help.  Silvercollection.it has quite a collection of French maker's mark initial reference. 925-1000, also offers references to search with more additional images. There is no accessible list of modern makers of gold and silver objects anywhere that we have found.
