What is an old mine cut diamond?

It is an early hand-cut style from the 18th and 19th centuries, with a small table, high crown, large culet and irregular facets. It sparkles in broad, soft flashes rather than the sharp brilliance of a modern round brilliant.

Is J color a problem in an old mine cut?

J color is near-colorless but shows a faint warm tint. Old mine cuts hide warmth better than modern cuts because of their high crowns and small tables, and the yellow gold setting softens it further.

How does this compare with a modern cushion cut?

A modern cushion is cut for light return and symmetry, so it looks brighter and more uniform. This stone trades that for antique facet patterns and a look no modern cut reproduces.

What does VVS2 clarity mean here?

VVS2 means very, very slightly included: tiny inclusions that are hard to see even under 10x magnification. In an old mine cut, the facet pattern also helps mask them.

Is the hidden halo visible?

A hidden halo sits under the diamond, so it is seen mainly from the side and adds sparkle around the gallery. From straight above, the ring reads as a solitaire.

Is a 1.3 ratio elongated?

Yes, 1.3 is slightly longer than wide, so the cushion looks a touch oval on the hand. That ratio is common in antique cushions and flatters most finger shapes.
