I understand that escrow is a money warranty.
Maybe I must explain.
I have a period of monetary liquidity unavailability.
I have credit sources in banks, but I do not want to use credit bank support.
Peru is a dificult market for my merchandise.
That is why I want to make business worldwide.
I have top quality merchandise but most people in Peru still have doubts except when the deal involves citrines, topazes and amethysts, because Brazil that is close neighbor of Peru is well known supplier.
In Peru most people use to make jewel business with silver and crysocolla.
I am an engineer, I have verified the quality of my gemstones.
But only other engineer could understand easily if for example the subject is cryptography and maybe not many engineers.
About "Handle my terms", I am not english native.
What I ment is customize an agreement with an escrow business partner.
I don't think there is a lot of customizing to do. Most likely the escrow will be based on the gem being real. Possibly size not being off. But the biggest thing that they are real and the one's pictured and real.
All products will likely have the same escrow. You might want to find a good escrow and show everyone what a "handle my terms" escrow looks like. If you get it in writing and a good escrow then likely you will be able to sell here.
