Facts About Platinum
We are always keen to buy scrap gold jewellery at fair competitive prices
Platinum is the hardest of the precious metals,
it never tarnishes. Its intense luster remains intact over the
years, and it is completely hypoallergenic.
Platinum is extremely dense, and remarkably heavy. Much more
so than silver or gold. This property of platinum enhances and
ennobles the quality of the jewellery from which it is created.
The ultimate stability of platinum over the years is unmatched.
It does not wear, and its extreme level of durability offers
a profound guarantee of strength and longevity. When a customer
comes into our shop to have their great grandmother's ring cleaned,
invariably, the ring is made from platinum.
- Platinum requires special skills and tools to work with. The image above shows a platinum wedding band just after pre-polishing work was done on a lathe. The ring is already so polished it shows a reflection of the photographer taking the picture, even though it is spinning around at thousands of rpm.
- Platinum has an extremely high melting temperature. In its purest form it melts at 3214 degrees F, almost twice the temperature needed to melt 14 ct gold.
- All the platinum ever mined would produce a cube 17 feet on each side, less than 5000 cubic feet.
- It takes up to 10 tons of ore to produce one ounce of platinum, more than twice as much ore that is typically needed for an ounce of gold.
- Platinum is not susceptible to problems like stress corrosion or stress cracking as can be the case with white gold. (This problem mainly applies to prong settings etc. Don't worry, your white gold wedding band will not suffer this problem).
