Old Mine Cushion Lab Champagne Loose

The softly rounded corners are the defining feature of this Old Mine Elongated Cushion Cut Diamond, giving its oblong cushion outline a smooth, balanced profile that reflects the charm of antique hand cut diamonds. Unlike sharper modern cushion cuts, the gentle curves create a softer face-up appearance while allowing the broad Old Mine facets to display slow, bold flashes of light. The delicate champagne tone adds warmth throughout the stone, ranging from soft golden beige to light peachy brown depending on the lighting, making this Old Mine Cushion Loose Diamond an excellent choice for vintage inspired engagement rings, heirloom jewelry, and bespoke center stone designs.

Available in 0.50 to 5.00 CT with VS clarity, this lab grown old mine cushion diamond preserves the high crown, deep pavilion, and open facet structure that define authentic antique cushion diamonds while offering the durability of a 10/10 hardness. The elongated proportions and rounded cushion silhouette create an elegant finger coverage, while the broad antique facets enhance the stone's natural depth instead of producing the uniform sparkle commonly seen in up-to-date vibes.

Whether selected as a Champagne Lab Diamond for a custom solitaire, a cushion cut loose diamond for a vintage engagement ring, or a unique center stone for bespoke jewelry, this Old Mine Cushion Diamond offers a distinctive alternative to traditional colorless diamonds. Its warm champagne hue pairs beautifully with yellow, rose, or antique finished gold, while the sustainable lab-grown origin provides the evergreen character of an antique cut with modern craftsmanship and ethical sourcing.
