An old mine cushion drawn long — roughly 1.25:1 — with the high crown, small table, and large open culet of the antique cut. The chunky facets turn light over in broad, slow flashes rather than fine sparkle. Cut in the antique manner, newly made, and set as a four-prong solitaire so the stone leads.Specifications Lab-grown diamond · D–F color · VVS+ clarity · IGI certified Made to order in 14K or 18K gold (yellow, white, rose) Band width: 1.8mm Hand-finished, ships in 12–16 business days Lifetime limited warranty for manufacturing defects · one complimentary resize within 1 year of delivery · eligible unworn pieces: 30-day returns Frequently askedIs this a real diamond? Yes. Lab-grown diamonds are chemically and optically identical to mined diamonds — same carbon structure, same 10 Mohs hardness, same fire. The only difference is origin.What does “cut in the antique manner” mean? The stone is a newly made lab-grown diamond faceted to old mine geometry — high crown, small table, chunky facets, and a large open culet that reads as a dark window at the center. It returns light in broad, slow flashes rather than the fine sparkle of a modern brilliant.How is an elongated cushion different from a standard cushion? Proportion. A standard old mine cushion reads close to square; this stone is drawn to roughly 1.25:1, so it runs longer down the finger while keeping the same high crown and open culet.
