This neckace has 4 faceted color changing synthetic stones and is 16.5 in. long. The width of the piece at the drop is .75in. thick and the chain is .25in. wide. It is a hefty 68 grams. This piece has seamless transition from link to link and is great to wear with anything. I have placed it in a newer catagory than It really should be in because the hallmark is cut off. It says 925 and a cut off Mexico and anything else was lost entirely. This is such a great wearable piece it is worth your jewel box! Just, LOOK AT THAT NECKLACE!!
