One silver European charm snake chain bracelet - ~3mm wide. This is not solid sterling silver but a copper metal bracelet plated .925 sterling silver. Some of my bracelets are stamped on the side, or the top, of the clasp.
Once you decide on your design you need to know what size chain to purchase - keeping in mind that you may start with a lot of charms and/or beads but eventually take those off and only have few beads. The charms and/or beads take up chain space so buying an 7" chain will not have wrist space of 7" once charms and/or beads are put on. If you are not sure what size your wrist is just use a tape measure, piece of ribbon or string, place around your wrist in a manner that you like to wear your bracelet. Then you can just measure that length with a ruler.
Once you have this measurement you will need to add another 1" to 1-1/2" to that measurement to come up with the size bracelet chain you will probably need (1 inch = 2.54cm or 1cm = 0.393 inch). These bracelets are usually purchased in "cm" length so you would need to add length to your original wrist measurement in order to accommodate the charms and/or beads you will be using.
