Precious metal laws, regulations and decisions. Summary of main changes


[1473-1799] [1800-1899] [1900-1999] [2000- ]



¤ Goldsmiths informed that they must move to the towns and cities. Practising the profession elsewhere is forbidden.

¤ The first gold fineness order: 19 carat (= 791/1000).

(Pure gold = 24 carats, 1 carat = 12 graania, or 288 graania = 24 carats)



¤ Goldsmiths must now mark their products with their signature mark or initials.

¤ Fineness is now controlled by the guild association.



¤ Silver fineness: 14½ luoti (906).

(Pure silver = 16 luoti, 1 luoti = 18 graania, or 288 graania = 16 luoti)



¤ Gold fineness: 18½ carats (771).



¤ Silver fineness: 14 luoti (875).

¤ Gold fineness: 22 carats, 2 graania (923).



¤ A nationwide assaying system is now introduced. In practice this is administered by Oltermanni (similar to wardens) in the guilds.



¤ Finland now has its own officials for assaying precious metal products.



¤ Silver fineness: 13½ luoti (843).

¤ Town marks are now introduced (in practice town marks will only later become common).



¤ Silver fineness: 12 luoti (750).



¤ Silver fineness: 13½ luoti (843).



¤ Decisions are made by the trade college on gold fineness: tukaatti gold: 23 carats, 6 graania (979), pistoletti gold: 22 carats, 6 graania (937) and kruunu gold: 18 carats, 5 graania (767).

¤ Town marks operate in practice 1689-1754. The punches are in the possession of the Oltermanni (similar to wardens) and are struck on a product after it has been assayed.

¤ Fineness assaying is performed by taking a metal sample from the product. This leaves a zigzag pattern called the Oltermanni line.


1752 (effective 1754)

¤ Fineness assaying is now handled by kontrollilaitos (control organisation - similar to the assay office).

¤ Every gold and silver product has to now be struck with a hallmark of three crowns. In addition, each has to be struck with town and maker marks.

¤ If you are now found guilty of having made a product of illegally low precious metal fineness, the punishment now (in addition to the confiscation of the product) is a fine of 200 riksdaler for first offence, 400 riksdaler for the second, and penal servitude for life for the third.

¤ Gold fineness: tukaatti gold: 23 carats 5 graania (976), pistoletti gold: 20 carats 4 graania (847) and kruunu gold: 18 carats 4 graania (764).

¤ Gold fineness marks: 23K, 20K and 18K.

¤ Silver fineness: 13¼ luoti (828) .




¤ Small gold and silver products (rings, earrings and such like) are now made exempt from hallmarking.



¤ Date marks are introduced using letters. Larger towns have already been using their own date marks before this time.

¤ The punishments for the manufacture of low-fineness products are reduced. 50 riksdaler for the first offence, 100 for the second offence and the loss of reputation and master rights after the third offence.



¤ It is now compulsory to mark gold products over 1.74 grams and silver products over 3.32 grams (with the exception of so-called 'peasantry jewellery').


[1473-1799] [1800-1899] [1900-1999] [2000- ]



¤ In order to safeguard domestic production, foreign imports of gold and silver objects are now banned. This restriction will apply until 1852 (with some minor exceptions).



¤ Finland now establishes its own kontrollikonttori (assay office) in Turku.

¤ The hallmark is now changed to a single crown shape (previously three crowns).

¤ New date marks are introduced. The new letter-series begins again from 'A'.



¤ The kontrollikonttori (assay office) now moves to Helsinki after the Great Fire of Turku.



¤ Supervision of hallmarking is now passed to a government superintendent.



¤ Silver fineness marks 13 and 13L (luoti) and 78 and 84 (Russian zolotnik) are in use concurrently.

(Fine silver = 96 zolotnik)



¤ Hallmarking is passed to the assay office under the control of the Mint.


1886 (effective 1887)

¤ Due to the transition to the metric system, fineness now start to be measured in parts per thousand (millesimal).


1891 (effective 1892)

If neither of these can be used, the base metal has to visibly differ in colour from the precious metal. It can not be used for strengthening, filling or increasing the weight.

¤ Base metal materials can be used if they are visibly different from the precious metal, if they have not been plated or otherwise modified to look like precious metals, and if the quantity is clearly visible.

¤ Cutlery handles can include non-metallic materials if no more is used than is necessary for the fastening of the handle.

¤ Combining precious metals: gold can have platinum elements and white gold can be rhodium coated (plated), silver can have gold and platinum elements and can be gold or rhodium coated (plated), platinum can be rhodium coated (plated). For technical reasons, you can use parts made from lower fineness precious metals and/or base metals, but these parts have to be individually marked accordingly.

2000 onwards (effective 2001)

¤ Coatings (platings): the fineness mark on a coated (plated) product has to indicate the fineness of the precious metal that has been applied.  No parts made from base metals or other materials and coated (plated) with a precious metal can be used in a product offered for sale as being made from precious metals. Acceptable coatings (platings) were listed previously (1977).

¤ The hallmark indicates the assay office. The hallmark has to always be struck onto the product and has a crown on a heart-shaped shield. The hallmark can also contain an assay office's unique identifier. The hallmark is now approved by Tukes upon application. Previously Tukes only accepted the hallmark.

¤ The responsibility mark indicates the importer, manufacturer or seller who is responsible for the product and its conformity with requirements. Only capital letters are approved for responsibility marks, though marks registered previously are still acceptable. Tukes now approves mark applications and keeps a register of responsibility marks. The owner of the mark has to notify of any changes and re-confirm the registration at intervals of three years (previously two years).

¤ The locality mark shows the locality of manufacture. The mark has to take the form of a coat of arms. A municipality can apply to Tukes for a locality mark. Previously only registered locality marks were valid.

¤ Other marks: other marks cannot bear confusing resemblance to marks used in Finland. However, marks in use in other EU/EEA countries can be used.

¤ Precious metal fineness is now - gold: 375, 585, 750, 916 and 999; silver: 800, 830, 925 and 999; platinum: 850, 900, 950 and 999. 969 gold is abolished.

¤ Now exempt from marking: gold and platinum products of less than 1 gram (previously less than 2 grams); silver products of less than 10 grams.

¤ A precious metal product can now voluntarily be hallmarked in the assay office (previously hallmarking was mandatory).

¤ Estates of bankrupt or deceased persons, auctions, etc. are omitted from the regulations.

¤ Previously, a precious metal product could only contain more than one precious metal in exceptional circumstances.

¤ Precious metal products can now be sold with a gold fineness of at least 375 (previously 585), silver fineness of 800 (previously 830) or a platinum fineness of 850 (previously 950).

¤ All precious metal products being sold have to now display a responsibility and fineness mark to show that the product is genuine. Previously, the date and location marks also needed to be present. Now these can be excluded if desired.

¤ Assaying of precious metal products and hallmarking by the assay office is now made voluntary. Previously, hallmarking was mandatory.

¤ Tukes is now entitled to take market samples of precious metal products for inspection. The samples have to be compensated at a fair price.

¤ If a product does not meet Tukes requirements, they have the right to forbid sales, to request product changes or to determine how one must act with regard to the product. The responsible party may also be required to cover the price of the product and assaying cost.

¤ The regulations can now be reinforced by a fine or the threat of having the product made by someone else at the offender's expense.

¤ Regulation breaches can now be punished with a fine, in which case the profits gained by the breach may be surrendered to the State.

¤ Products marked in other EU/EEA countries are accepted in Finland so long as the marks contain the same information required of Finnish products.



¤ Cutlery, candlesticks, and similar products can now be made using reasonable amounts of lower fineness precious metal solder, metals or other substances. Product descriptions relating to the fineness have to be readily available in retail outlets.

¤ Hallmarking may now be made by a laser.

¤ Precious metals can now display marks used in other EU/EEA countries.

¤ Fineness deviation is not allowed.

¤ If a precious metal product on sale does not bear the required marks, customs, bailiff authorities, auction houses, pawnbrokers, estates of bankrupt or deceased persons and assay office have the right to provide a written certificate in place of the marks. Product fineness must be recorded in accordance with the actual fineness.



¤ A precious metal product for sale must contain either a responsibility and fineness mark or a hallmark and fineness mark.

¤ The manufacturer or seller is responsible for ensuring that the product is properly marked.


2008 onwards (effective 2009)

¤ Palladium is added to the regulations: fineness must be at least 500.



¤ The precious metal fineness of palladium solders must be at least 500.

¤ Responsibility marks can be used on non-precious metal products if the product clearly states that it contains no precious metals.

¤ Precious metals can now include marks in use in other EU/EEA countries (the list is not restrictive).

¤ Palladium fineness: 500, 850, 950 and 999.

¤ Fineness marks no longer need to be used with the base shield.

¤ Palladium fineness mark shape: symmetrical trapezium with three equal sides half the length of the base.

¤ Palladium marking is exempt on products of less than 1 gram.

¤ If a lightweight product is marked, it must have at least a fineness mark (previously also the responsibility mark).
