I may be way late for this party, but I was unaware of jewelry being made via platinum over sterling.  I'm assuming it doesn't tarnish...  which would be really nice (so far, this is true, they are not tarnishing).  I bought these earrings to get a good look at the material more than to wear them.  So my recommendation is:  If you like large CZ stones, these earring are very, very handsome.  They were also extremely well priced, so hopefully that will be true of an expanded line.  Overall:  Good purchase.
