This is just odd.  I don’t say good or bad, just odd.

My neighbor’s daughter asks me if I can resize a ring she bought from Blue Nile. Nice enough ring, fairly priced.

She tells me the ring is 18kt White gold.  I look inside the shank and it is stamped PLAT.  So she gets me the original description and receipt from Blue Nile.  The description says white gold ring with platinum prongs.

I have never heard of that combination.  On top of which, why would you stamp the shank Plat, if only the prongs on the center stone were Platinum. 

It’s six hours later and I’m still scratching my head.
