Disney Enchanted Belle Diamond and White Sapphire Rose Heart Pendant Necklace 14k and Sterling silver 18"

This is a pre-loved pendant from the Disney Enchanted collection, for princess Belle. It comes on a replacement rhodium plated sterling silver fine rope chain that is 18". 

The pendant itself is a good amount of SOLID 14k gold. It houses a 2.5mm natural white sapphire. I've not conducted any other test on this, other than visual inspection and diamond tester. The stone looks like a diamond with inclusions and all, however my diamond tester states sapphire--so I'm going to err on the side of caution. 

The sterling silver portion of the pendant features about .10ctw of natural I12/HI diamonds.

The piece as a while weighs 2.7g.
