Precious Metals, Gemstones & Diamonds

We understand that choosing your precious metal, gemstone or diamond can be daunting.  We've put together some information to help you with this process.
We make our fine jewellery in 9ct gold (yellow, white or rose), 18ct (yellow, white or rose) and Platinum.
How to decide between White Gold or Platinum?
Although both of the precious metals are white metals, the two are very different. White gold is in fact actually yellow gold mixed with at least one white metal alloy - such as nickel, manganese or palladium - to give it its white(ish) colour. As White gold is not naturally white, it requires maintenance from time to time and is finished with a layer rhodium to give it its iconic bright white colour. At Thorpe & Brown we offer white gold in either 9ct or 18ct. Platinum is a denser metal. Its chemical composition means that Platinum alloys do not tarnish. The properties of the metal make Platinum more grey in colour than White gold. At Thorpe & Brown our Platinum is hallmarked at 950. Price is another factor that differentiates the two metals, however metal price fluctuates daily so it is always best to check with one of our expert staff. 

Diamonds

There are many factors involved when choosing a diamond, not least the price point.  We can help guide you through the process, and discuss the following pointers;

CLARITY

quality factors

Clarity grades assess the number, size, relief and position of inclusions and blemishes.  We always recommend choosing a diamond with no visible inclusions to the naked eye, and above.

COLOUR

quality factors

The less colour, the higher the grade. Even the slightest hint can make a dramatic difference in value.  Our diamonds are always graded as White & above, to ensure that crisp diamond brightness.

CUT

quality factors

Cut (proportions, symmetry and polish) is a measure of how a diamond’s facets interact with light.  This is the most important factor for us, once the clarity & colour and covered.  A well cut diamond makes all the difference!

CARAT WEIGHT

quality factors

Rarity means larger diamonds of the same quality are worth more per carat.  We will help find the perfect size for you.
