Sterling Silver 925

Fine silver (99.9% pure) is generally too soft for producing functional objects; therefore, the silver is usually alloyed with copper to give it strength and durability.

Sterling silver is an alloy of silver containing 92.5% by weight of silver and 7.5% by weight of copper. The sterling silver standard has a minimum millesimal fineness of 925. Millesimal fineness is a system of denoting the purity of silver by parts per thousand of pure metal by mass in the alloy. For example, an alloy containing 92.5% silver is denoted as "925".

At 316 Treasures we carefully select sterling silver jewellery from manufacturers who guarantee and adhere to the 925 standard. Thus the “925” stamp will appear on all sterling silver jewellery to indicate the authenticity of the jewellery.

We strongly recommend that you store your Silver Jewellery in an air tight plastic sleeve to avoid any Silver Tarnish, (which is a discolouration of Silver); this only affects the appearance of the jewellery as it can be cleaned with silver polish.

Stainless Steel 316
Stainless steel was once regarded as a metal for use within medical practices and within our kitchens, but recent times has shows that certain grades of steel (316L), can be used in the creation of fashionable jewellery; such as rings, bracelets, necklaces, pendants and so on.

There are over 150 grades of stainless steel, of which fifteen are most commonly used. The type of stainless steel which is used for jewellery and watches is the”316L” grade. It can be re-finished by any jeweller and will not oxidize or turn black, in fact 316 stainless steel does not stain, corrode, or rust, unlike ordinary steel.

Stainless steel jewellery is the fastest expanding type of jewellery around the world with unique designs becoming available all the time. It is especially popular in men's bracelets, necklaces and rings, however a large number of stainless steel jewellery can also be seen which is designed for and by women.

Tungsten Carbide

Tungsten carbide is approximately three times stiffer than steel and is much denser than steel or titanium. Tungsten is 10 times harder than 18kt gold and 4 times harder than titanium, tungsten carbide has been widely used for decades in industrial applications such as ball point pens, cutting tools, mining machinery, and even rocket engine nozzles.

Tungsten carbide can now be found in most jewellery shops, it is most notably used as the primary material in men's wedding rings. When used in this application the bands appear with a lustrous dark hue often buffed to a mirror finish. The finish is highly resistant to scratches and scuffs, holding its mirror-like shine for years.
