925 Sterling Silver // 925 sterling silver is a precious metal containing 92.5% of silver and 7.5% of other metals, usually copper. Fine silver or pure silver (99.9%) is too soft to produce jewellery and is therefore mixed with copper to give strength while still preserving the beauty of the precious metal. Our jewellery at Hemera & Nyx is nickel free. 

325 gold // 325 gold is a precious metal consisting of 32.5% pure gold and is usually mixed with copper, palladium, manganese or zinc. This translates to approximately 8 kt gold.

Acetate // Acetate is a man made material that can be used to create plastic or chemical fibre. They are created by fusing wood pulp to a variety of acetic acids.

Alloy // An alloy metal is created by combining two or more metals together to give it more strength or resistance to corrosion. Examples of this could be bronze and zinc. When Hemera & Nyx releases an alloy collection, it is always metals that are not sterling silver.

Baroque Pearls // Baroque Pearls are naturally formed and are not spherical in shape. They are unique and each pearl is different in size. When purchasing baroque pearl pieces, we try to pair them up as closely as possible, but the beauty of these pieces is that each pearl is different. The pearl is formed by inserting a plastic or shell nucleus inside a mollusc.

Base Metal // Base metal indicates a metal that is not precious or semi-precious like sterling silver or gold. It usually refers to metals that oxidise and corrode easily like iron, copper, nickel, lead and zinc.

Brass // Brass is an alloy of copper and zinc and because of its bright, gold like appearance, malleability and low melting point it is usually used in jewellery making.

Bronze // Bronze is an alloy consisting copper and usually tin. Bronze looks similar to rose gold due to its copper content, however the metal can range from yellow to brown in colour.

Cubic Zirconia // Cubic zirconia (also known as CZ) is a synthetic material created by treating minerals like calcium oxide, under extremely high temperatures in a device called a skull crucible. Cubic zirconia is a cheaper and more durable alternative to diamonds as it had s similar structure and appearance to natural diamonds.

Electrochemical plating // Electrochemical plating is a chemical process that fuses various layers of of metal into one solid piece with a layer of gold placed on top. It is also referred to as displacement plating and is not used as often as electroplating.

Electroplating // Electroplating is a process that fuses various layers of of metal into one solid piece with a layer of gold placed on top via an electrical current or hydrolysis. Other forms of plating include electrochemical plating.

Gold // Gold is a precious metal that is mealeable and often used for jewellery. It is usually combined with stronger metals like zinc and copper, and is rated on its karat amount. The general rule is, the higher the karat amount, the higher the gold content and the less durable it is. You can see gold jewellery in yellow, rose, white and green.

Gold Filled // Gold filled jewellery is similar to plating, where gold is fused with another metal but should not be confused. Gold filled jewellery includes a layer of gold that is mechanically bonded to another metal meaning its thicker, longer lasting and has 100 times more gold. Both are still great processes, although gold filled jewellery is much more valuable, tarnish resistant and does not rub off or change colour.

Gold plated // Gold plated jewellery refers to jewellery that has a thin layer of gold applied to the top. There are many ways in which plating can occur, including electroplated and electrochemical plating.

Nickel // A metal used in many jewellery pieces which can cause allergic reactions in some people. Hemera & Nyx does not use nickel in our sterling silver pieces.

Pre-Order // When customers are able to place an order for a product to be shipped out before a dedicated date.

RA Number // In the case that you would like to return or exchange an item, you will be allocated an Return Authorisation number (RA number). This number must be provided when you send the items to us.

Reconstituted Turquoise // Reconstituted turquoise is created by crushing natural turquoise into a powder form and setting it into the preferred shape and size. This is done to ensure that each piece is closer in colour and shape. Sometimes, sometimes blue or green colouring is added to make the gemstone brighter.

Rhodium // Rhodium is a precious metal part of the platinum family. It is usually used in jewellery so it is scratch resistant.

Rhodium Plated // Usually used in European markets, rhodium plating is used with white gold jewellery as it is scratch and tarnish resistant. It is also used to plate sterling silver and slightly changes the colour to look more like white gold.

Rose Gold // Rose gold is created by mixing gold and copper. It is sometimes referred to as pink or red gold, and is the strongest gold of the three as copper is very sturdy (yellow gold vs white gold vs rose gold).

White Gold // Contrary to popular belief, pure gold is reddish in colour. White gold is created by mixing yellow gold and a silver metal, usually sterling silver, manganese or palladium which is part of the platinum family. This can be used to plate sterling silver.
