Old Mine Oval Cut Diamonds Wholesale

An Old Mine Oval is an oval-outline diamond cut with Old Mine character — a high crown, a large open culet, and chunky, hand-style facets — instead of the squarish-cushion outline the Old Mine Cut is traditionally associated with. Guru Diam stocks 18 Old Mine Oval diamonds on hand, CVD lab-grown, IGI-gradable on request.

What an Old Mine Oval actually is

The Old Mine Cut is a faceting style, not just an outline — see our Old Mine Cut vs Old European Cut guide for the full definition of what makes a stone read as "Old Mine": high crown, small table, open culet, and irregular hand-cut-style facets that throw broad, warm flashes instead of tight brilliant fire. The classic Old Mine outline is a squarish cushion with rounded corners. An Old Mine Oval takes that same faceting character and applies it to an elongated oval silhouette instead.

Why buyers ask for this combination

An oval outline reads modern and elongating on the finger; Old Mine faceting reads warm and antique. Buyers who want an oval's flattering, elongated shape but don't want the crisp, high-contrast sparkle of a modern oval brilliant ask for this combination specifically — it's an antique-style alternative for buyers who've decided a squarish cushion isn't the outline they want, without giving up the open-culet, candlelit character that draws people to Old Mine cuts in the first place. It's a request that comes up most often in custom work, where a client has already settled on "Old Mine" as the look they want but needs an outline that fits a specific finger shape or existing setting better than a cushion does.

How it differs from a standard oval brilliant

Where it fits in a catalog

Old Mine Oval sits alongside our standard Old Mine Cut and other antique-cut inventory as a specialty line — see our antique cut diamonds guide for the broader category. It's a low-volume, specialty item rather than a stocked-deep staple, which is typical for antique-character cuts applied outside their traditional outline. Buyers sourcing it should expect to work from current on-hand stock and, for larger or custom orders, plan around cutting to spec rather than pulling from deep parcel inventory.

Sourcing and matching

Guru Diam stocks Old Mine Oval as individual stones and can match pairs on request for stud or side-stone use, following the same matching approach used across our Old Mine and antique-cut inventory.
