Gold fineness: how to choose a chain’s metal and understand gold fineness
Why is it important to know the chain’s metal?
When choosing a chain, it is important to consider not only its length or weaving style, but also the precious metal it is made of. When choosing a chain, it is especially important to understand gold (gold) and its properties – colour, fineness (carat) and value, as these aspects determine the quality and appearance of the jewellery piece. The metal determines the chain’s appearance, durability, weight and comfort. In addition, an unsuitable metal can cause skin irritation or quickly lose its aesthetic appearance.
What is a chain’s fineness and how to understand it?
Fineness is a numerical designation that indicates how much pure gold or other precious metal is in an alloy. Fineness shows the relative (relative) amount of pure gold in the alloy. It is marked in thousandths of parts: for example, a 585 fineness chain contains 58.5% gold, and the remaining part of the alloy mass is made up with other metals, such as silver, copper and nickel. The carat (carats) system is also used to mark gold purity, where 24 carats means pure gold.
Which finenesses are most commonly used for chains?
The most popular gold finenesses in chains are 375, 585 and 750 – these are standardised levels, often marked as are 375 585 750.
- 375 fineness (9 carats): an economical choice, but gold is only 37.5% of the total alloy – it wears out faster and can change colour.
- 585 fineness (14 carats): a balanced choice, suitable for both everyday and occasional wear.
- 750 fineness (18 carats): has the most pure gold, looks luxurious, but is softer and requires more maintenance. 24-carat gold is one of the gold finenesses and means the pure gold level.
Gold colour: what is determined by the alloy?
Gold colour depends on the composition of the gold alloy. Gold of different colours, for example, white and rose gold colours, are obtained by using different alloy metals. A combination of silver and copper is often used in yellow gold chains. The white gold shade is obtained by mixing gold and white gold composition often contains palladium or nickel, often the chain is plated with rhodium. Rhodium is a precious metal with which white gold is often plated to give it shine and resistance. Rose gold (also called pink) is obtained when the amount of copper dominates in the alloy. The colour does not affect the gold fineness, but changes the chain’s style and suitability for the skin tone.
Platinum – an exclusive choice for chains
Platinum – one of the rarest precious metals used in jewellery. It is naturally white, highly durable and hypoallergenic, making it perfect for sensitive skin. Unlike white gold, platinum is not plated with rhodium and retains its shade all the time. It is often used in luxurious chains that are passed down from generation to generation.
What is the difference between gold and platinum chains?
Gold – lighter, can be of various colours, more affordable and versatile. Platinum – heavier, naturally white, rarer and more expensive. Both metals have different advantages, but the choice depends on the needs: aesthetic, allergic or practical.
Fineness and chain durability
Fineness is important when choosing a chain not only for value, but also for strength. That improper care or frequent wear can affect the appearance and durability of lower fineness chains. 585 fineness chains are suitable for everyday wear – they are neither too soft nor too hard. Meanwhile, 750 fineness variants – great for an occasion, but require gentler care.
What does the hallmark say?
Every chain must be marked with a hallmark, which confirms the amount in the alloy of precious metal. This is supervised by the Lithuanian Assay Office, guided by the regulations of the State Supervision of Precious Metals and Gemstones of the Republic of Lithuania. The mark guarantees the product’s compliance with the declared fineness.
Is a higher fineness – always better?
Finenesses are not only about the amount, but also about the intended use. Although the gold fineness 750 looks prestigious, for everyday use a 585 fineness chain is often more suitable. It is sturdy enough and retains a beautiful appearance.
What to choose for everyday wear?
A 585 fineness gold chain is most suitable for everyday wear. It is resistant to environmental impact, retains the gold colour and does not cause allergies. If you have very sensitive skin, it is worth considering platinum as well.
What to choose for special occasions?
For gifts or special occasions, it is recommended to choose a gold fineness of not less than 585 or platinum. Such chains not only look luxurious, but also remain valuable for many years.
Does colour depend on fineness?
It is not the fineness, but the alloy composition that determines the chain’s colour. 375 585 750 fineness chains can be of both yellow, white, and rose gold, therefore the colour is more of an aesthetic choice.
How to make sure of the product’s quality?
When buying a chain, it is important that it is certified according to the regulations of the State Supervision of Precious Metals and Gemstones of the Republic. This ensures that you get a quality and valuable jewellery piece.
