homie dont buy ANYTHING ONLINE when its comes to bling
one of the best bling you can get is from ITALY
they only fuck with 14K plus but some times they will plate it 18k on a 14 k chain just to make it more shiny but U know that shit will wear off
not to mention the higher the grade of carat the weaker chain will be, do to the fact that its has less alloys in it
check ebay as a reference and shop around
I was looking for a diamond cut franco chain like this one

no luck gotta get it custom made
make sure its got grab like lock like this
or better
and 4 diamonds atleast VS1
the more cuts its got the more light will penetrate and BLING!color is factor also I LOVE CANARY DIAMONDS!
Russians are experts in making synthetic diamonds so watch out
but diamonds are a very bad investment
hope this somewhat helps you out and please when u get that picky POST PICS!!!
