SJM diamond jewellery - any good ?

[Dhana]

I have been recently seeing a few hoops in the real real made by SJM
I haven’t heard of them before and was just wondering if anyone might know about the quality ?

When I googled it this is what I found:
“SJM is the trademark of the S & J Diamond corporation”.
Looks like they are jewelry wholesalers located in NY and in business since 1998.

I am curious what other PS’ers know about SJM.
