A gift given lovingly or just another link in the chain that bound Rose? Does' it really matter, it's a DIAMOND! This is the ONLY authorized reproduction of The Heart of the Ocean necklace. It was reproduction by the J Peterman Co back in 1998 as a limited edition(it is rumored that the limited edition was never complete because the company went bankrupt so all production immediately stopped and there is even less of an limited edition)with a Certificate of Authenticity that states "This Certifies That The Enclosed Necklace Is An Authorized Reproduction Of "Heart of the Ocean" Necklace As Seen In The Motion Picture "Titanic" " and Is now sold out at the source and can't be reordered and as you can imagine are very rare to come by. It was recreated from the mold of the original prop Heart of the Ocean necklace.The 18 inch necklace is made of 84 brilliant faux diamonds set in a precious platinum-like rhodium plate setting. The 1 3/4" heart-shaped blue faux 75-carat diamond solitaire is encircled by a row of faux diamonds, and is detachable from the necklace. It comes with no DISCLORATION of any kind or DAMAGE to the necklace, the certificate of authenticity, or the box. Also comes with the original white cover sleeve that goes over the box and the original foam padding also has NEVER BEEN TAKEN OUT OF THE BOX and i have kept it all in the original shipping box from The J Peterman Co. and I also still have the original invoice from J Peterman.
