Yes. It is a 1/10 carat round lab-grown diamond, which has the same structure as a mined diamond but was made in a lab. It is not cubic zirconia.

Will the brass tarnish?

Brass with silver plating can tarnish and the plating can wear off over time, especially with sweat, perfume and water. Keep it dry and store it in a pouch to slow this down.

How big is a 1/10 carat diamond?

A 1/10 carat round diamond is roughly 3 mm across. The halo setting adds sparkle around it and makes the pendant read larger than the stone alone.

Is $19.99 a good price?

It is the only new price listed as of November 6, 2026, so there is no recent range to compare. At under $20 for a lab-grown diamond pendant, it is inexpensive for the category.

What chain length does it come with?

It comes on an 18-inch chain, which sits around the collarbone for most people. That length layers well with shorter or longer necklaces.

Is it good for a gift?

It suits a low-budget gift, a first diamond or a stocking stuffer. The plated brass means it will not hold up like solid gold, so set expectations for daily wear.
