Welcome to GW Studio. Please contact me with any questions you have. This bracelet is sterling silver & the stone is sleeping beauty turquoise. The stone size is 4 mm. BRACELET SIZING 1. Use a flexible measuring tape or piece of string, & gently wrap it around the wrist, just below the wrist-bone, in the same place where you would wear a watch. 2. If you used a string then lay the string out straight & measure it using a ruler. 3. Depending on how you want the bracelet to fit, my general guidelines are to add one of the following to your wrist size. Add 1/4" to 1/2" to the measurement for a snug fit. Add 3/4" to 1" inch for a relaxed fit. Below is a size chart. Please note the AGES are ESTIMATES ONLY. It is best to GO by WRIST SIZE.
