Are these earrings solid gold or plated?

They are 14K white gold, so the metal is solid gold alloy, not a plated base. White gold is usually rhodium-finished for a bright white look, and that finish can be refreshed over time.

How wide are they and will they feel heavy?

The band is about 6.8 mm wide, and three rows of diamonds across that width add real weight. Expect a substantial hoop that some wearers notice more than a thin single-row pair.

What kind of backs do they have?

They use hinged backs, which snap closed through the post and are generally more secure than friction backs. That makes them a practical choice for a heavier hoop.

Are the diamonds certified?

Zales lists the total diamond weight and round shape but does not present these as certified stones. Ask for the color and clarity grades before buying if those matter to you.

How do they compare with single-row diamond hoops?

A single-row hoop shows one line of stones; these show three, so the sparkle is denser and the look is dressier. The trade-off is more weight and a wider profile that sits further off the ear.
