The Baltic Proud Raw Amber Necklace is generally sized for infants, typically between 11 to 12 inches (around 28 to 30 centimeters). This gives it a comfortable fit without too much slack, which is important for safety. However, exact measurements aren't always mentioned in descriptions.

It's worth noting that some folks have had issues with the screw clasp breaking, possibly because it's designed to be gentle for little ones. So, while it's supposed to be durable for everyday wear, you might need to replace it occasionally.

Luckily, the manufacturer offers a 1-year guarantee, which is nice if something goes wrong.

For safety, you should always supervise when a child is wearing the necklace, especially because it could be a choking hazard if left on overnight or during naps.

Overall, these necklaces are pretty popular among parents looking for natural teething remedies. Some believe amber releases soothing succinic acid when warmed by the skin, though it seems to work differently for each child.

So, if you're considering giving it a try, just keep safety and supervision at the top of your list.
