US lab grown diamond producers/sellers seem like they're in more abundance than in Europe, with companies such as 1215engagement, brilliant earth, puregrowndiamond and d.nea. Does anyone know of comparable companies in Europe in cities like Brussels/Antwerp etc.?
If there are firms/jewelers that come to mind, then how would you regard the quality of their stock and prices vis-a-vis US firms?
