FACTS ABOUT THE STERLING SILVER COLLECTION

Maria Black jewellery is made of .925 sterling silver and all jewellery receives a plating.

The jewellery has either a polished or mat surface. Please note that a mat surface will become shinier with wear.

These surface treatments will fade over time because of contact with clothes, hard surfaces, sweat, perfume, hairspray, air pollution and others.
Everyday or very frequent wear, may speed up this process, especially on items like rings and bracelets, which have more frequent contact with surfaces.

The platings are as follows:

  • Mat 18K yellow gold.
  • High polished 14K yellow gold.
  • High polished 18K rose gold.
  • High polished white rhodium.
  • Mat black oxidation. 

 

Mat 18K yellow gold, high polished 14K yellow gold and high polish 18K rose gold platings are in the gold family. 14K and 18K refer to the colour of the metal. All is in fact plated with 24K gold.

The silver colour is plated with rhodium, which is a very hard metal that comes in black and white – it is used to protect the silver from oxidising.

For the gold and rhodium platings, 3 micron layers are added on to build up thickness, thus the plating lasts longer. In theory it should last a year, but this varies in accordance to how often the jewellery is worn.

Rings wear the quickest, because they get touched/banged constantly, thus for rings it could be less than a year, while earrings can sometimes last 2-3 years.

The black jewellery is oxidised, this is done by a solution that speeds up the natural oxidisation process of silver. This however means you cannot ‘add’ layers of oxidation and therefore it will rub off within 1-2 weeks. This is supposed to happen. The black oxide is meant to give the jewellery an antique two tone finish with wear - this is not a claim. 

 

FACTS ABOUT THE FINE JEWELLERY COLLECTION

Every single piece of jewellery in the western world is stamped with alloy numbers and the name of the maker. Therefore Maria Black jewellery is stamped with 750 if 18K or 585 if 14K and with BLACK,which is the hallmark. 

Gold is very rarely sold pure because of how soft it is in its pure form. Therefore we use different alloys. An alloy means that the gold is melted together with different metals to control colour and hardness of the gold. 

PLATING METALS

Rhodium : You can plate fine gold to create 2 tones or a different look. Rhodium is used for this. Rhodium is either black or white and used as a liquid plater on other metals. All white looking 14K jewellery from Maria Black Jewellery is plated with white rhodium as standard. 

All platings rub off. For instance you will notice the black rhodium rubbing off any base metal, but the white on 14K white gold, you won’t notice. It will last roughly a year but will rub off on exposed surfaces and it will most likely last forever on non-exposed surfaces.

DIAMONDS

When talking about diamonds there are 4 things to consider.

They are called the 4 c’s : Colour - Cut - Carat - Clarity. 

Colour
Diamonds come in all kinds of colours naturally, but the white diamond is the most notorious and desirable, thus more expensive. Diamond colours used are white, champagne, nougat, cognac, chocolate coloured or black diamonds. Brown or black diamonds are not graded. They only have the carat, which is referring to the weight. The black diamonds are always colour treated, as they do not occur naturally in black (actually they do, but it’s so rare they are very expensive).White diamonds are always graded. The colour G/H is the grading for the white diamonds used in Maria Black Jewellery, which is considered a very good quality. 

Cut
Cut refers to the shape and cutting method of a diamond. The brilliant cut is used for Maria Black Jewellery. A brilliant cut will be round and it means the diamond has a very specific cut to enhance the reflective shine in it. If the cut is wrong you can have the most flawless coloured diamond, but it won't sparkle and shine as much as a lesser quality diamond. This category is often ignored, but is the most valued in Maria Black Jewellery. 

Carat (abbreviation Ct or just C)
This is the weight of a diamond, measured in carats. As the carat weight of a diamond increases, so does its rarity and therefore its price. One carat is divided into 100 “points,” so that a diamond of 75 points weighs 0.75 Ct. The carat-weight of a diamond is the easiest measurement to determine. Most importantly, two diamonds can be of equal carat-weight, but their value can differ greatly due to their cut, colour, and clarity. 

The diamonds used in Maria Black jewellery are tiny for pave setting mostly. They vary from 0,9 mm to 1,5 mm.
Important: For all Maria Black Jewellery the total Carat weight refers to all diamonds in a piece of jewellery, this is normal for the industry.

Clarity
Clarity refers to flaws and blemishes inside a diamond. These can be big or so small that they cannot be seen with the human eye. Maria Black Jewellery uses the quality called S/I - which means Slightly Included. This in practice means that, there is a tiny spec or specs inside the diamond, but you won't be able to see it unless you use a 10x magnifying class. 

 

PRODUCT CARE

  • When you're not wearing your jewellery you should keep them in a safe and secure place, like your bedroom.
  • Do not keep your jewellery in the bathroom because all of the moisture from your shower and sink will make the sterling silver pieces tarnish extra quickly.
  • Jewellery boxes are a great place to keep your jewellery, but you should keep in mind that it does not protect the sterling silver pieces from tarnishing and oxidation.
  • Avoid direct contact with water and chemical products e.g. soap, perfume, abrasive products. 
  • Do not wear jewellery when in the swimming pool, jacuzzi, sauna/steam room or while bathing or showering. 
  • Chlorine, detergents, oils, moisturizers & perfumes can all cause tarnishing and damage. 
  • Remove jewellery when doing household tasks. 
  • Avoid impact with hard surfaces as much as possible. 
  • Make-up, perfume & hairspray all contain chemicals, which may dull the finish of your jewellery. 
  • Gently wipe jewellery clean with a soft cloth after each wear to remove make up and oils (from skin). 
  • Coil chains gently to prevent damage in storage. 
  • Don’t yank or pull chains.  

 

Remember:

You should treat your jewellery like any other wardrobe item. 
Clothes and shoes must be maintained ei. washed, new soles, cleaned, repaired etc. The same goes for jewellery.
The gold plating must get a new gold layer on when needed, and it is advised to check locks and clasps for firmness.
