I have about $4800 in store credit to
Diamond Nexus Labs.
They sell lab-created diamonds in various types of jewelry. The credit is infinitely divisible, so this can be used for any item they sell regardless of price. I will give a 25% discount on anything you buy for using the store credit, 35% if you take the whole thing. The numbers are completely firm and if you lowball me then I will go troll all of your strat threads.
I can accept almost any form of payment and will ask for payment up front unless you're super reputable. I will also be completely discreet in case you don't want people to know your bling wasn't machete'd from the hands of a 9 year old African child.
