In today's rapidly developing market of making synthetic and treatment Gemstones, identification of these treatments & differentiating the Natural from the Synthetics is quite difficult for a Gemologist, As compared to the old times.
We are an organization dedicated to the field OF GEMSTONE and RUDRAKSHA Identification for the development of trust among the consumers by our certification services. As an independent certification body our opinion is fair, accurate .
We at PJC-GRTL take great care of your Gemstones while testing them. We start by weighing the stone, and then we record its Dimensions with precision. Next step is to check its physical properties like surface structure , hardness etc. and then optical properties (Luster, Heft, Phenomenon, if it's a diamond we use a master stone to decide its colour). The next step is checking the stone under "Polaris scope" to see whether it is SR, AGG, ADR(SR) or DR. After that we take R.I. (Refractive Index) using the "Refractometer" and then we calculate its S.G. (Specific Gravity). than Pleochroism using "Dichroscope", observe the stone under "UV light" (Short & long wave). And Then check its spectrum in the "Spectroscope" , At last we observe the Gemstone under the Microscope, to see its inclusions. On the basis of the above mentioned tests performed on the Gemstone we reach a conclusion on our Experience basis and identify the Stone.
