MATERIAL INFO
METALS
I solely work with precious metals that are nickel free. My jewellery collections are made of 18 carat gold (750) and 925s Sterling silver, and certain wedding rings are made of 14 carat gold (585) or white gold.
Many of my pieces are also made in oxidized silver. This is a surface treatment of silver taht makes the piece appear raw and elegant at the same time.
GOLD
Gold is a popular metal for jewellery making based on its aesthetics and malleability. Gold is measured in carat. 1 carat represents 1/24 of the whole and 24 carat is thus 99,9 % pure gold. The higher the carat, the softer the material. Because of it’s proneness to be scratched easily, making jewellery for everyday use in 24 carat gold is not desirable. Due to this and in order to create more robust and durable jewellery I either work in 18 or 14 carat gold.
Gold
All of my jewellery in (yellow) gold are made in pure gold and alloys with silver and copper. They are all allergi friendly and easy to maintain.
18 carat gold is stamped 750 – consisting of 75 % pure gold and 25 % pure silver and copper.
14 carat gold is stamped 585 – consisting of 58,5 % pure gold and 41,5 % pure silver and copper.
White gold
All my jewellery in white gold are made in pure gold and alloys with palladium, silver and copper. They are all allergi friendly and easy to maintain.
White gold obtains its white color due to the amount of palladium.
14 carat white gold is stamped 585 – consisting of 58,5 % pure gold and 41,5 % palladium, pure silver and copper.
Silver
The finest silver (99,9 % pure silver) is too soft to make everyday jewellery, and therefore it alloys with other metals (mainly coppor) to create more durability.
All my silver pieces are made in Sterling silver.
Sterling silver is stamped 925s – consisting of 92,5 % pure silver og 7,5 % kobber.
Oxidized silver:
In my oxidized silver jewellery the alloy is the same since the oxidization is a surface treatment of Sterling silver.
DIAMONDS
I work with white and black diamonds coming exclusively from certified Danish suppliers. This is the only way I can be certain that the diamonds are purchased in a responsible fashion.
White diamonds:
The quality of the diamond is very important. I use Top Wesselton VVS diamonds in “brilliant cut” that gives a beautiful shine and glow.
Black diamonds:
I mainly use black diamonds in “rose cut”. This cut only has facets on the top of the diamond and therefore preserves most of its mass.
DIAMONDS: THE 4 C’S
The value of diamonds are based on the 4 C’s: Carat, Color, Clarity og Cut
Carat
Carat is the weight unit of diamonds (not to be confused with carat in gold that represents purity). 1 carat equals 0,2 gram. Large diamonds are rare and the price of the diamond therefore grows exponentially with the size of the stone.
Color
The color of diamonds can be seen on a spectre from colorless/white to a yellow nuance. GIA has classified diamonds on a scale from D-Z: D being the colorless and thus more rare stones. As the color of the stone intensifies, it moves along the scale to Z that represents a more yellow or brown nuance.
Clarity
Perfection is hard to reach – and the same goes for diamonds. Small irregularities, also called inclusions, often resides in diamonds even though they can be difficult to see. The more clear and flawless a diamond is, the more valuable it is.
Cut
The cut of a diamond has an immense impact on how the light is reflected – and how much the diamond then will glow. The most popular cut is the “brilliant cut” that has 57 facets in all.
