What is the best metal & why?
In the market place, there is so much misguided information for the consumer which makes it very difficult to decide what the best metal is for a Diamond or precious Gemstone.
Let’s get some hard facts out of the way first:
- Platinum is the most durable of all precious metals.
- Platinum weighs approximately 1.4 times heavier than 18ct white gold.
- 18ct white gold is harder than Platinum. I know what you’re thinking. How can this be?
- 18ct white gold requires re-coating every one to two years, Platinum does not.
- Both Platinum & 18ct white gold do mark, dent and get scratches at a similar rate.
- Platinum is more expensive than 18ct white gold.
Now that we have got that out of the way, let’s talk about the two precious metals.
Platinum is the most durable metal due to its density. In other words, for the same volume of metal, Platinum is 1.4 times heavier than 18ct white gold & in turn makes it more durable than 18ct white.
PACIFICA RING – Handmade in Platinum
Think of it like this, 18ct white gold is hard and more brittle than Platinum. So when 18ct white gold takes a hard knock, it will be left with a scratch/dent; and on a very small scale, a small amount of metal will be worn away during this hard knock. This is part of wear and tear. On the other hand, if we apply the same hard knock to Platinum, it will be left with a scratch/dent just like 18ct white gold. However, rather than the metal getting taken away, it gets moved to the side (this is not visible to the naked eye) and this is why Platinum is the most durable of the two metals.
ASSCHER CUT DIAMOND RING – Handmade in 18ct White Gold
18ct white gold’s natural colour is grey. However, when new, it will have a special coating on it. This special coating is called rhodium and requires re-coating every 18months/24months. Platinum does not require coating at all and is naturally white in colour.
Platinum is a more expensive metal due to it being a rare metal and also due to the fact that when making a ring, a gold & platinumsmith will need to start with 1.4 times more platinum than 18ct white gold. Also, the other reason is that Platinum requires a higher skill level to be able to work with it properly. It does take a little longer to make a piece of jewellery in Platinum rather than 18ct white gold.
