RADHA RANIGEMS Certified Natural Opal Pendant Locket 5.25 Ratti / 4.52 Carat (Australian Opal) Brilliant Cut Certified Astrological Gemstone

It's not a stone, but it is plastic which is supplied with certificate. You can check out the picture which is proof that it's not a stone. The shinyness is at one side that too not uniform. Other side is plain without shine. It is actually glitter which has settled at one side. Please stop making fooling people. This product does not deserve 1 rating also.
