Are the diamonds on the front and back of the hoop?

Yes. Inside-out hoops set stones on both the inner and outer faces, so the diamonds show from the front and the side. That is the main difference from a standard diamond hoop.

How big are the diamonds?

The listing does not give a total diamond weight here. Ask the agent for the carat total and stone count, since inside-out hoops usually use small accent diamonds rather than large ones.

Is 14k white gold good for everyday earrings?

Yes. 14k white gold is a solid gold alloy and resists wear better than gold plating. The rhodium finish that gives it the bright white look can wear off over years and be re-plated.

Do these work as a gift for a mother?

They are a common Mother's Day and anniversary gift because the hoop shape is easy to wear and the diamonds add occasion. Check her preference for white gold versus yellow gold first.

What should I compare them with?

Compare with plain 14k gold hoops, which cost less and never lose stones, and with single-row diamond hoops, which sparkle less but often use larger stones. Inside-out hoops trade stone size for all-around shine.

How do I care for them?

Wipe them with a soft cloth and keep them away from perfume and hairspray. Store them separately so the stones do not scratch, and have a jeweler check the clasps and settings once a year.
