Old Mine Cut Diamond Rings: Character and Buying Details

Old mine cut diamonds appeal to people who enjoy a less uniform outline and broad flashes of light. Their charm comes from the individual stone rather than a promise that every example will look alike. A ring with an older cutting style can also have a newer setting, so ask about the center and mounting separately.

What defines the cutting style

GIA’s old mine cut guide describes a generally squarish outline, small table, high crown and prominent culet. Proportions vary. A rounded rectangular shape alone does not prove that a diamond is an antique old mine cut.

What this gallery illustrates

The original photographs show a large halo ring worn with a wide bracelet. They provide a useful sense of scale and setting height, but do not establish the center’s age, cutting classification or grades. The side view makes the raised structure beneath the halo easier to see.

Inspect an older ring carefully

Request the available grading information and have the stone edges, prongs and mounting examined. Look at the diamond in more than one kind of light. There is no single color or clarity threshold that makes every old mine cut the right choice.
