This beautiful bracelet makes a wonderful gift. Choose up to 10 birthstones on your custom-made bracelet. I hand-make this using quality sterling silver chain and an easy-to-use lobster clasp. The lovely Swarovski crystals measure approximately 6mm. Birthstones will be placed on the bracelet in the order that you note.** HEART CHARM BRACELET: I also offer this bracelet with a heart charm (last two photos): www.etsy.com/listing/768324203/mothers-birthstone-bracelet-with-heart SIZING - IMPORTANT - PLEASE READ Measure snugly around the wrist and add 1/2 inch to get your bracelet size. I now add a 1 inch extension chain - please note if you do NOT want this added. The 1 inch extension is added to the end of the bracelet (for example, if you select a 7 inch size, your bracelet will fit 7-8 inches). ----------------------------------------------------------------------------------------------------- **Please note that Swarovski uses the same crystal color (Siam) for both January and July. If you need both of those months, I recommend not placing them side-by-side.
