They Should Just Call them Cat's Eyes - Not Opal
Nice little box with the earrings on a card, a little bag, a wiping cloth, and an extra set of keepers for the earrings.  They are pretty much cream colored, the gold plating looks pretty good, as do the simulated stones. They are not an expensive item and probably look better than their price would suggest.  I would call them decent costume jewelry.  I am not sure why they chose to call them opal, cat's eye is more accurate, or maybe moonstones.
