Cutting True Antique cushions:

The most beautiful diamonds in the world by Leon Mege

This style of a ring available for custom orders with stones purchased through Leon Megé only.

This style is best suited for elongated stones such as cushions, emerald and oval cuts. This is the style to caress and nurture your soul. Skip the Champs-Élysées crowd in favor of Place Vendôme style and sophistication. Truly a one of a kind ring, designed to announce to the world that you have arrived.

Exclusive True Antique™ French cut diamonds are set in a seamless channel of fiery diamond crystals. Held by almost invisible walls the custom cut diamonds flare toward the center in a brilliant explosion engulfing the center stone. The esthetically eye-pleasing curvature of the flare is a product of logarithmic calculations applied to golden section and Euler's identity (e iπ + 1 = 0).
