Is this the price of pure Platinum?

Yes. Every figure here is for 999 fine Platinum. Jewellery in this metal is usually 950, which is 95 percent pure and worth proportionally less. Shops also add labour and margin on top.

Why is the world price quoted per ounce?

Precious metals trade internationally in troy ounces, which is 31.1034768 grams. Local markets quote grams instead, so this page shows both: the ounce price above the table and the gram ladder inside it. The troy ounce is not the everyday ounce of 28.35 grams.
