Anyone tried the brand Marco Valente?

[A.Ali]

I came across this brand from one of my friends and were quite surprised by the quality of thier diamonds. I am considering buying from them and wanted to ask if anyone owns any of thier jewellery?

Some of the prices seem quite high especially for SI diamonds
