From the photographs they do indeed appear to be very pretty and well made earrings however, regarding the pair I received, the main stones showed excessive white cracks throughout which were visible even to the naked eye.  Viewing the stones under 10X magnification didn't look any better.  A white, sticky substance was present on the stones.  Although the description doesn't say, these might be fracture filled rubies.  I have returned them to amazon.com for a refund.
