At Sophia Alexander, we believe in using the very finest precious metals available to make your personalised fingerprint jewellery.
9ct Gold, 18ct Gold, Platinum, Palladium, Titanium, Argentium Silver and Sterling Silver.
Every piece of fingerprint jewellery and every personalised fingerprint gift made by us, is hand crafted by a team of experts using traditional jewellery making techniques.
They are forged using beautiful molten gold and silver, never fired metal clays to create heirlooms that will be loved for a lifetime.
We believe we create the very best jewellery for our clients worldwide, working to the highest standard.
Here we explain the precious metals we work with and why our fingerprint jewellery is a little different to other companies out there.
Fine silver (99.9% pure), is a very soft precious metal, often not considered suitable for making “high-street quality” objects, as it tarnishes quickly and can be damaged easily. It is commonly combined with copper to make a stronger and more durable Sterling silver.
Sterling Silver is perhaps the most popular silver readily available for sale. In the UK, to be hallmarked as 925 Sterling Silver, the silver has to be made from a combination of at least 92.5% fine silver and 7.5% copper. The copper alloy gives the silver strength whilst preserving its beautiful appearance.
In the UK, Sterling Silver is always free from Nickel.
Argentium Silver is a premium quality silver identified by it's "flying unicorn" hallmark.
It is purer than traditional sterling silver and has a brighter white colour than platinum, white gold and traditional sterling.
It is easy to care for, simple to clean with a long lasting shine.
Pure Gold, or 24 Carat gold is very soft and may not be considered suitable for jewellery or other items that will be in daily use.
Like fine silver, it is usually combined with other metals to improve its strength and durability.
A number of different elements are commonly combined with gold to improve its natural properties and alter it’s colour, resulting in more durable yellow, white and rose gold.
Silver and Copper may be added to gold to harden it. Depending on the amount of each metal added, Silver whitens the colour of the gold and copper reddens it.
Palladium and Zinc are commonly added to whiten gold. Nickel may also be added to harden the gold and also acts as a whitener (but the amount of Nickel that can be added to jewellery in the EU is restricted).
9ct Gold is the most common type of gold worked with and sold in the UK. It is a combination of 37.5% pure Gold and 62.5% other metals making it harder and more durable. It is considered harder than 18ct gold as it has a lower pure gold content.
18ct Gold contains more pure gold than 9ct and may have a deeper yellow colour. It is a combination of 75% Pure gold and 25% other metals.
Although it is softer than 9ct gold, it is still commonly used in the production of fine jewellery as it is well able to withstand daily wear and tear.
18ct White Gold is almost always plated with the hard white metal “rhodium” to enhance the “white” appearance.
Platinum is an extremely rare and pure metal with a silver / white, lustrous appearance. It is highly resistant to wear and tarnish and considered to be extremely un-reactive making it perfect for producing fine jewellery and a good choice for those with sensitive skin.
Palladium is another extremely rare precious metal which shares many characteristics with platinum.
It has a silver / white appearance, but is harder and even lighter in colour. It is one of the three most popular metals used to make white gold alloys, as it is highly unlikely to cause allergic reactions.
Titanium is a beautiful white / silvery coloured precious metal found as mineral deposits throughout the earth.
It is known to be highly durable and light weight with a high tensile strength and is resistant to damage from many chemicals, so will not be corroded by chlorine or sea water amongst other things.
It is particularly suitable for people who suffer from allergies to metals as it is largely hypoallergenic. It is a popular choice for gents wedding and commitment rings as it tends to be more resistant to physical wear and tear.
