To help you to understand the differences between the materials used in the Annele jewelry, we have written down the main information of the jewelry metals. This knowledge is good to know when purchasing any kind of jewelry, not only ours, as these are very common types of metals used. Take a second to read this if you have ever wondered what kind of jewelry are you wearing.
Solid gold is the highest in purity and price and its value is based on its radiant colour and shine, which won’t either tarnish or fade with time. Pure gold is respected throughout the world and it is a great investment.
Gold is a very soft and malleable metal and the higher the karat, the softer and more malleable the item is. Because of this, pure gold is not the best option for jewelry and its often made into an alloy by mixing it with other metals to create a stronger metal. These alloys retain gold’s beautiful properties while it becomes a more practical metal for everyday wear jewelry.
Gold-filled (also known as rolled gold) is gold mechanically bonded using heat and pressure to a solid brass core. By law, gold-filled jewelry must contain 5% gold by weight to be called such. As a result of this, gold filled items are stamped with a karat number that indicates the purity of the gold used in the gold layer.
Gold-filled jewellery won’t tarnish or fade easily and people sensitive to metals are able to use them without an allergic reaction. The layer of gold is thicker than regular gold plating and can be worn daily without fading even as long as 20 years. 
Gold-plated jewelry is made by using electricity or chemicals to deposit and bond a very thin layer of gold over another metal, usually brass. Brass is an alloy of copper and zinc, and for people with nickel allergy, brass is very unlikely to cause any reactions as it does not contain nickel at all. Brass is a very good choice for jewelry due to its workability and durability. We use also 925 Sterling silver in our gold-plated jewelry. You can read more of Sterling silver below.
Gold-plated items are much stronger than solid gold items and they will last longer in everyday use. Gold-plating is a great way to make a strong and durable jewelry product with the appearance of gold. 
The downside is that the gold layer starts to fade and tarnish over time because the molecules of the base metals eventually transfer into the gold-plated layer, causing it to break down. With the right care of gold-plated jewelry, you can prolong the life cycle of your item.
Sterling silver, also known as 925 silver, is a combination of metals and is known as a metal alloy. Fine silver contains pure silver 99% whereas sterling silver is 92.5% of pure silver and 7.5% of other metals, usually copper. The addition of other metals makes silver significantly stronger and easier to use in jewelry. For a timeless piece, sterling silver is a better choice than fine silver.
To quickly identify sterling silver from other white metals, most of your sterling silver jewelry will be stamped with a mark called Hallmark, which is usually a stamp of “925”.
As silver is prone to tarnish, you can polish it regularly to keep your jewelry looking its best. Discoloured silver is quickly fixed by rubbing it with a cloth and a cleaning fluid.
