Platinum is almost as expensive as gold. So this can not be Platinum. (sorry

)
If it is platinum, please give me the sellers name, and I will buy all his stock and stop working
It does not look like silver either. probably some nickel alloy.
But in the end, it is not the material that is important.
You must like the keris and be happy with it.
My favourite keris are dressed in wood with hardly any silver to it.
Best regards,
