They made an appointment with us on mid June and
checked several materials such as Tantalum and Hafnium.
They had chosen Hafnium as their wedding rings.
Tantalum and Hafnium are the double top popular metals as
I always tell.
Hafnium has beautiful white silver shine, no color changes,
no metal allergy and no elution, so you can keep Hafnium rings
beautiful with no maintenance.
At the strength, Hafnium's vickers hardness is around HV200;
ex; Platinum is HV30, Pt900 is HV60, Hafnium is much harder than Pt
so scratch resistant and no deformation occurs.
On the other hand, Only Areva company in France can purify Hafnium so
that not many can buy.
Also the process is difficult so only our Daikanyama studio can make
rings from Hafnium that is only one studio in the world.
This time, the design was good fitting smooth curved one.
They got their only one Hafnium order made wedding rings!
