Is aquamarine durable enough for a child to wear daily?

Aquamarine sits around 7.5 to 8 on the Mohs scale, so it resists scratches reasonably well but can chip with hard knocks. A child who is rough on jewelry may do better with a harder stone.

What size is the gemstone?

The stone is a 3mm round aquamarine weighing about 0.1 carat total. That is a small, understated size suited to a child's finger.

Is 10K gold real gold?

Yes. 10K gold is about 41.7 percent pure gold alloyed with other metals, which makes it harder and more scratch-resistant than 14K or 18K.

Does it come in other birthstones?

This ring is made for March with aquamarine. Other months would need a different ring from the same birthstone line.

Can it be resized as the child grows?

A plain gold band like this can often be resized by a jeweler, but repeated resizing wears the metal. Check with a jeweler before buying if you plan to size it up later.
