Because we appreciate the subtle colour of pure precious metals we
choose not to plate our fine jewellery and all of our precious
jewellery is fully assayed and hallmarked. |
| |
|
These photos are intended to show the colour variations of the
metals that we use. Please note that the colours you see will vary
between different computer monitors and therefore will also vary
from the actual metal itself. |
| |
|
The differences between metals of different types and purity is not
just the colour difference - which can be quite subtle - but also
differences of weight, density and hardness. At the bottom of
this page is information
about these weight and density differences. |

Metal hardness and density |
| Because pure Gold and Silver are relatively soft in their pure
states various other pure metals are added to the gold and silver to increase
its durability and strength - which is what the carat (or karat)
mark indicates. This is the same for all Silver and Gold not just
ours. |
| |
| We use Silver that is marked 925 which means that it is 92.5% pure
silver with the other metals making up the balance. |
| |
| For our 9ct we use Gold that is marked 375 which means that it is
37.5% pure gold with the other metals making up the balance. |
| |
| For our 14ct we use Gold that is marked 585 which means that it is
58.5% pure gold with the other metals making up the balance. |
| |
| For our 18ct we use Gold that is marked 750 which means that it is
75% pure gold with the other metals making up the balance. |
| |
| For our Platinum we use Platinum that is marked 950 which means that
it is 95% pure Platinum with the other metals making up the balance. |
| |
| The hardness of the metals is a bit more complicated. |
| |
| Starting with the White metals, Platinum, White Gold and Silver:
Platinum is the Mike Tyson, hard as they come. Then 18ct White Gold
is then the hardest followed by 14ct White Gold and lastly 9ct White
Gold which is slightly harder than Silver. |
| |
| Yellow Gold: 14ct Yellow Gold is harder than 9ct and 18ct Yellow Gold, which are both as soft as each other. |
| |
| Red Gold: 18ct is the hardest followed by 9ct which is harder than
14ct Red Gold. |
