what is patina?
Patina in Middle Eastern jewellery
Published March 18, 2024
Patina is a word you’ll see used often when talking about ethnic jewellery. It may be described as ‘having great patina’, and collectors may be afraid that cleaning ‘removes the patina’. But what is patina? You may be surprised to learn that it is used for two very different things!
Patina in ethnic jewellery: what it technically is
Corrosion. Patina refers to the thin layer that develops on the surface of metals due to natural oxidation and environmental exposure over time. You could think of the greenish hue that bronze statues or architectural elements may have, for example.
But it encompasses a broad spectrum of colours and textures, ranging from earthy browns to deep blues and reds. Patina is a result of the metal’s reaction with elements like oxygen, moisture, and sulphur. As such, it is technically the same as tarnish.
In some types of jewellery, patina is actually prized: it indicates that the jewel is indeed old. But, beware: there are tons of ways to create a fake patina on jewellery!
Patina, rust, tarnish: what is the difference?
Technically, none. They are all words for the oxidation in metals. But patina is often used for the colour effects in particular, while tarnish is more often used for the oxidation itself.
What is more, patina carries a positive connotation, as something beautiful. Tarnish, on the other hand, is used in a negative sense, as something damaging and ugly.
You will also find patina used for bronze, rust for iron, and tarnish for silver: all three denote oxidation processes and their visual results.
There are many different interpretations of the word patina going around, and to add to the confusion, collectors may mean something completely different!
Patina in ethnic jewellery: what collectors also mean by it
Usewear. Very often, the word ‘patina’ is used for something else entirely in the world of ethnography and collectors.
You will find it applied to a particular type of wear: ‘usewear’ refers to the physical evidence of wear and tear that occurs over time as a result of the item being worn or used in its intended manner.
Patina, in this context, usually means the soft wear on a surface as a result of years of rubbing or handling it. Other types of usewear, such as dents and scratches in a piece of jewellery are not called patina.
Although patina is technically the result of oxidation in metal, you will also see the word used with regard to wooden objects in the world of ethnography.
Here, too, it means ‘usewear’: a wooden handle that has been grasped countless times, will have a beautiful, deep colour and a silky, smooth surface. The same goes for antique furniture where doorknobs, edges and surfaces may show discoloration and a softness after decades of use.
Patina in ethnic jewellery: what it definitely is NOT
Dirt. Honestly. Dirt is not patina. Dirt is an external substance that accumulates on the surface of jewellery. Dirt is easily removable with gentle cleaning methods. It does not alter the metal itself, like oxidation does, but can obscure the intended aesthetic of the piece.
Cleaning (see 3 methods how to approach that) can effectively remove dirt without impacting the authentic patina that may have developed over the years. The jewellery you see in the gallery above is just dusty and dirty: this is not what patina looks like!
Patina in ethnic jewellery: how to check for authentic patina
So, as we have seen, there are two types of ‘patina’ you can inspect your jewellery for.
Oxidation – Many ethnic jewellery pieces are made from materials like silver, bronze, or copper, which can develop a natural patina or oxidized layer over time due to exposure to air and moisture. This patina is often uneven and may be more pronounced in areas that have been frequently touched or worn.
Polishing and wear patterns – Certain parts of the jewellery, such as clasps, hinges, or chains, may show signs of polishing or smoothing from repeated use. Additionally, wear patterns may emerge on surfaces that come into contact with the skin, clothing, or other jewellery pieces, indicating areas of frequent movement and friction.
You can inspect an item for traces of usewear by employing various methods:
1 Use your eyes: Start by taking a good look at the jewellery. Carefully inspect the surface of the jewellery under good lighting conditions. Identify areas that are likely to show signs of wear and tear, such as the back of a pendant or the inside of a bracelet, and observe these closely. Look for scratches, patina, polishing marks, and any other indications of use. Note: the jewellery needs to be free of dirt to do this – dirt may actually obscure exactly these details.
2 Magnification: Whip out the magnifier! Check for subtle details such as fine scratches or tool marks. Patina, both in the sense of oxidation and usewear, may have been artificially applied.
3 Feel: If you’re looking to see if a piece has indeed been worn for a prolonged period of time, stop looking and close your eyes. Feel the jewellery: does it feel worn and soft, or do you still feel sharp edges? Open your eyes again and check these places on the jewel.
Patina, whether oxidation or usewear, is often used as a factor in authenticating a piece. But there is more to that than patina: this article gives 5 tips on how to establish whether your jewellery is authentic!
