Just a little note to say when Jewellery firms list items that say a length of chain is for example is 16", this is usually the whole chain from clasp to clasp! not the length from clasp to bottom centre - if you measure a necklace down from the clasp to the bottom centre and it is 8" then the full length would be 16" !
When listing items I try to let my customers know what size chains necklaces are - and if I don't we always answer questions if need be. Most of my necklaces are on 16" - 18" chains or on thong.
All have a good day and hope to see you soon.
