first undo the figure 8 on the side. that will pop off at the hinge.
second push doen on the side or top, there is a little bump of metal that sticks out.
this may take 2 people to do, you;ll have to tug hard.
next it might be like a pearl clasp. depending on the diamond wt of the bracelet.
if it's like a pearl clasp. you'll have to twist this out. if not
push down on the bump of gold and pull hard. this is all set up for your safty.
different locks are done differently. do you know your ct. wt? usually over 7 ct. there
are two figure 8 sides locks. try this hope it helps.
