I have here for sale a stunning addition to your jewellery collection in this 925 sterling silver pendant necklace set with six sparkling ruby gemstones. I have included a short video clip showing the hardness of the stones with a diamond tester, a jewellers way to check for coloured glass or real gems, and as you can see the stones rise to the top of the scale which suggests these will be most likely synthetic ruby's at least at the price i am asking !
