| When it comes to diamonds, it's a must to buy those who have certification. It's the only way to be sure that the stone isn't fake, but many people don't know all the importance. GSI is a gemological laboratory where you can grade your gem and get gemology certification will all the stone characteristics. The laboratory uses only modern equipment to provide the best and accurate grading results. |
