Transitional Cut
The transitional cut is the round diamond that bridges the old European cut and the modern brilliant — early-to-mid 20th century, with a foot in both worlds.
What is a transitional cut?
A transitional cut is a round brilliant from roughly the 1920s–1940s that sits between the old European cut and the modern brilliant. It typically has a larger table and a smaller culet than an old European, but more warmth than a modern stone.
History & why it matters
It reflects the moment cutting moved from candlelight to electric light and from hand to early machine work, spanning late Art Deco and retro jewellery.
