Hafnium has a higher melting point than platinum I already have two diamonds 3.5mm and a nice alexandrite center stone 8x6 and a small block of Hafnium metal just need someone with the skills nad knowhow to fabricate the thing

jewlers will not normaly be able to melt this stuff as it has a super high melting point try buying some rod then put through a ring extruder with a 4mm d profile as it is very ductile solder in a oxygen free atmosphere and fabricate the claws with a milling maching and some file work yes be carfull as it is liable to catch fire in small filings it should be ok to wear as it is NOT poisenous or about the same as any other metal it is similat to zirconium and titanium which is also used in jewellry
should look so nice

Almost any jeweler COULD make this ring for you,but I'm not too sure how many WOULD or SHOULD. Casting it may not present great problems, but machining it is regarded as difficult and hazardous.

From OSHA:

"Effects on Humans: Hafnium and its compounds are mild irritants of the eyes, skin, and mucous membranes [Hathaway et al. 1991]. No industrial poisonings involving hafnium have been reported [Hathaway et al. 1991]. "

None of the literature I've accessed has contemplated the deliberate wearing of the metal.

Care needs to be taken when machining hafnium because when it is divided into fine particles, it is pyrophoric and can ignite spontaneously in air. Compounds that contain this metal are rarely encountered by most people and the pure metal is not normally toxic but all its compounds should be handled as if they are toxic (although there appears to be limited danger to exposed individuals).

We used to use Hafnium to coat laser optics at a job I used to have. It is very difficult to work with and I think it would be too difficult for a jeweler to make into something that looked attractive.

bad idea. Your hafnium could easily explode if machined. Ask a machinist to do it, and tell them to treat it like titanium. It ought not to explode if they're smart.

I think that if the melting point of platnium is a valid concern for you, finding a good jeweler is not your biggest problem. If you are ever anywhere that the ring would melt, you'd probably be dead.
