I’m not sure what your problem is. The cost of this stone is way beyond 10k. I have a deposit with my broker and we have detailed pictures of the gemstone to ensure that no swap is made. We know where all the fractured are as well as the inclusions. We have been buying from his family for generations.
Trust me when I say that in this part of the world being sued is the least of your problems. If you cheat someone you will probably just disappear.
I suggest you stop answering or being part of this post. I honestly regret ever posting on here about this stone or any other of the emeralds.
