I bought a pair of earrings similar to these in concept during Nordstrom’s annual sale this summer. Mind have a small clear cubic zirconia at the top, and a smaller one right under the earlobe. I really like how they give a different look to the ear (though they can be a tad fussy to put on).
The concept is the same with these pretty earrings available with three different coloured stones and finishes. These are gunmetal plated with what Nordstrom is describing as “stabilized opal” accented with clear crystals. I will take that to mean synthetic opals, but they are nice nonetheless. Available for USD$130.
