Metal allergy free Hafnium wedding rings

The client has light metal allergy so he required the followings;

Material; Hafnium

Design; Simple wedding rings

Size; Want to check at the studio

No stone

 

We shaved Hafnium to flat shape and mirror finished.

 

Hafnium forms very strong passivation film, so most acid and

alkali are not eluted that mean metal ion isn't eluted, too.

Then there are no causations for metal allergy.

 

Hafnium powder may be eluted to strong alkari, but hard ring isn't

eluted even in strong alkali.

 

The beautiful pair ring made from pure Hafnium mass are their

special wedding rings.

 <Comment from clients>

Mr. Hirose, Thank you always.

We got rings and we are so happy that you made

such a wonderful ones!

 We really regret that we couldn't visit you and

receive our rings by hands.

We wanted to say thank you face to face.

We wear our rings forever!

 By the way, I have one question about Hafnium.

I think our Hafnium rings are not very white though I thought

Tantalum is black and Hafnium is white.

Is my ring getting darker after several years by daily use?

 

<Comment from Hirose>

This color is Hafnium color that I showed you as a sample when we had a first meeting.

Of course Tantalum is much more black. Maybe you compared to trial sample rings that I sent you before. The sample rings are made from Aluminum and the color is really white. Hafnium doesn't change its' color after many years so

please don't worry for color change.
