MiabellaMiabella Solid 925 Sterling Silver Italian 5mm Diamond-Cut Figaro Chain Bracelet for Women Men, Made in Italy

Q: This says comes in size 6.5 inches but I do not see the option for buy?

Thank you for your inquiry. The 6.5 inch is back in stock.

Q: I want to use for a charm bracelet would this one work?

As long as the opening of the charm is smaller than 5mm it can slide on to the chain. But the style of this link is too long and won't allow charms to move freely sliding around. They will most likely get bunched up when one charm is stuck. You should get a round snake chain or something with smaller links to allow free spinning around the bracelet.

Q: What is the best size for a 12 year old

I believe I already answered this . . . maybe it got lost in cyberspace! My answer was, either a 6.5 or a 7.0, depending on the stature of the 12 year old? Hope this helps!

Q: Could the 6.5 fit a 7 year old?

Thank you for your inquiry. The 6 inch fits best for a 7 year old unless they have a larger wrist size. 6.5 inches is more common for 9-12 year olds and for women with very small wrists.
