You can get a proportion measuring scanner from Ogi or Sarin that can also have a laser inscriber.
This type needs to have the stone painted in liquid paper - correction fluid. There is a risk of chipping the girdle.
You can buy the same type, without scanner from Photoscribe - who are wonderful to deal with and give excellent support.
Or buy the top of the line Exemer ''cold'' laser from photoscribe for $100k >>> These do not neeed liquid paper and almost no risk of chipping
Thank You for the Reply.
But 100K ?! i think this is a bit expensive,do you know the price of the OGI and Sarin!?,
Chipping the girdle!?
did you encounter anyone that chipped the girdle by using the OGI or SARIN?
and do you know what should be the charge of such service?!
