Is the onyx a real gemstone?

Yes. The center is genuine black onyx, a variety of chalcedony that is dyed or treated black. It is softer than diamond, so avoid hard knocks against stone or metal.

How much diamond is in the ring?

About 0.04 carats total, in G–H color and VVS clarity. That is a small accent amount, so expect a subtle sparkle rather than a diamond-forward look.

Yes, it is 18K yellow gold throughout, not gold plated or filled. 18K means 75 percent gold, which gives a rich yellow tone and holds up to daily wear.

A jeweler can usually resize a plain gold band, but this design has stones set into the face. Ask a jeweler to check whether the setting allows it before buying a size that does not fit.

How does it compare with Gucci's other Interlocking rings?

This one pairs black onyx with a diamond accent. Other Interlocking rings use plain gold, mother-of-pearl or fuller diamond pavé, so choose this for the black-and-gold contrast rather than maximum sparkle.

What should I check when it arrives?

Confirm the 18K stamp inside the band, check that the onyx sits flush and secure, and look at the diamond setting for loose stones. Keep the box and paperwork for any warranty or resale.
