  • Designer's direction - People tend to overlook this one while shopping for diamonds. At Leon Mege we care a great deal for aesthetic look of your future jewelry and would gladly help you to find the best available option based on your preferences.
  • Pricing - If you found a stone already, we will beat the price and get you the exact one as all the stones come from the same source. We provide absolute transparency in every step. Clearly a win here.
  • Exclusivity -  Not only that we price match any stone you possible can find we also provide a special access to some stones that are not listed elsewhere - thanks to our long lasting partnerships with wholesale suppliers.
  • We work with any budget - Don't get intimidated by the large center stones that worth hundreds of thousands dollars, we still work with smaller stones and always happy to offer the best suitable option for you. 

We create only high-quality jewelry, with no exceptions. Nothing leaves our premises until it's guaranteed to meet the highest jewelry standards.


We recommend considering one of our past designs as a base of your own. We can modify or change any aspect of the design to make it uniquely yours. Our quality and style are superior to other luxury brands such as Harry Winston, Graff, and others.
