Why antique diamonds look different in candlelight

Compared with a modern round brilliant, an old mine or old European cut typically has a smaller table, a higher crown and a larger, open culet. Those proportions were not a compromise; they were a deliberate response to low, warm, flickering light.

The result is broader flashes of color and a slower, more liquid sparkle rather than the fine white scintillation a modern cut produces under a spotlight. In a restaurant at dusk, an old cut usually wins.

Because these stones were cut by hand, no two behave the same way. That is worth seeing on a video call before you buy, which is exactly what a private viewing is for.
