Old Mine Cushion Cut Lab Grown Diamond Pair

Some cuts belong to history and refuse to leave it, and the Old Mine Cushion Cut Lab Grown Diamond Pair is exactly that kind of stone. The old mine cushion predates every modern brilliant cut, its softly rounded corners, high crown, and deep pavilion producing a quality of light that feels organic and intimate rather than engineered, a glow that pulls the eye inward rather than projecting brilliance outward. These Loose Lab Grown Diamonds are available from 0.25 to 4.00 TCW in EF colour and VS clarity, offered as a perfectly matched Diamond Pair built for custom jewellery projects that deserve a foundation this considered.

These Old Mine Cut Diamonds are lab grown with the same chemical and optical identity as earth mined stones, scoring a perfect 10 on the Mohs hardness scale while delivering the antique fire and depth that designers seek in Old Mine Cushion Cut stones specifically. As Loose Lab Diamonds arriving free of any setting, creative control belongs entirely to whoever receives them. These Cushion Cut Diamonds at EF colour and VS clarity deliver the look of a century old cut with the consistency and precision of a modern lab grown stone, making these Cushion Diamonds as rare in character as they are reliable in quality.

These Loose Diamonds carry an ethical and transparent origin that earth mined stones cannot match, yet deliver the same beauty, hardness, and brilliance without compromise. Whether acquired as Lab Grown Diamonds for a bespoke engagement commission, chosen as Pair Diamonds for a symmetrical earring project, or selected as IGI Certified Diamonds where provenance and quality matter equally, these stones arrive with full certification confirming the authenticity and grade behind every facet.
