Hi welcome to the boards!
Moissanite does not not cloud over time. The Diamonna is moissanite, so no it will not cloud over time. Diamonna and Neo moissanite I believe are the only two moissanites with warrantees at this point in time. The warrantee covers basically anything that could happen to the stone, including clouding over time (even though it shouldn't), so even though the stone shouldn't cloud it's nice to know you have a warrantee!

He explained that lets say for example I bought a gem today for 1000 USD, and 5 years down the road you expect that the process to develop the Gem would decrease in cost. So if the gem costs 900 dollars 5 years from today, then you would only need to pay 450 opposed to 500 for a replacement.
To me this sounds very fair and reasonable that as the economy of scale increases then cost of possible replacement goes down so there is some confidence that the product is backed up in such a way.
Although I do not have the luxury to go to the west coast I wish I could see the gem in person.
I jumped the gun and bought a 2.4C H&A round loose gem. I am having it shipped to NC to be put together with the main ring
