Due to its high melting temperature (1795°C or 3263°F), its toughness and tenacious ability to clog files, and the incredibly time-consuming finishing process, not many goldsmiths make the successful transition to platinumsmith. Or want to. However, those same characteristics, primarily its toughness, make it extremely desirable as a jewellery material. From a consumer’s standpoint, maybe not so much so, since the high price and the scarcity of competent craftsman has undermined the reputation of a beautiful and highly versatile material.
One of the problems is that the most popular alloy of platinum, which contains iridium, is possibly not the best choice. Platinum alloyed with ruthenium, another platinum group metal, is harder and polishes up brighter, retaining the polished finish for much longer as well. Naturally, that’s what we use. It’s more miserable to work with than the other alloys, but the results are well worth the effort. What I'm trying to say here is that platinum is my favourite metal to work with, despite the "Goldsmith" moniker, and hey, it's darn near affordable compared to gold right now. Buy soon, buy often.
