    Hi Julia, Which platinum we are using for comparison matters. 

    All nickel based white gold is very hard, very resistant to bending
    or denting. Cracking is the risk with nickel whites for excessive
    hardness. Annealing white gold for fabrication is a real trick.
    Traditional platinum like 90Pt/10Iridium, and 95Pt/5 Ruthenium is
    fairly soft by comparison and has more chance of bending or denting.
    If one cast the same ring in 14kw and platinum they would se that
    platinum is nearly twice as heavy as 14KT gold. That makes one heck
    of an impression on the consumer that tries both on. 

    If your customer wants platinum, and there is a strength issue- Get
    one of the "heat treatable"  platinum's from Imperial smelting
    (Canada) Hoover & Strong, or even Englehard, perhaps via a
    distributor. 

Good Question!
Daniel Ballard
