Jewelry's gamut of variation runs wide and deep.  The styles, sizes, weights and color basically mean that you won't find the same piece of jewelry twice when shopping online or in a brick & mortar store.

That being said, that goes for these earrings.  I could not find a comparable set anywhere, until I visited Amazon (keywords: December Birthstone+Topaz+Earrings).  I had been searching for a pair of earrings for my girlfriend since her birthday was in December, and wanted to get her birthstone (because that shows thought, right girls?).

The earrings came enclosed in 2 boxes: the outer was your run-of-the-mill glossy white thin cardboard.  Open that up, and you're eyes land on a midnight blue velvet box.  The size/cut/description of the earrings are clearly labeled on the bottom of both boxes.  Opening the velvet box, the earrings jumped out at me.  The cut/color/clarity were excellent, especially at the $180 price.

I found a similar earring, though slightly smaller for $340 at Macy's.  These are a downright steal.  And as always, Amazon's shipping speed are bar none.  Flat out the best service of any online merchant.  Period.

It's a win-win.
