OldMine & Co.

Heritage Craftsmanship.
Timeless Brilliance.

Rooted in India’s legendary diamond heritage, Oldmine & Co. specializes in crafting rare antique-cut lab-grown diamonds inspired by the timeless beauty of vintage jewelry. Our legacy traces back to families connected with traditional Golconda diamond cutting artistry, where precision, patience, and hand craftsmanship have been passed through generations. Based in India, we manufacture unique old mine cuts, old European cuts, antique cushions, rose cuts, portrait cuts, and custom freeform creations designed to preserve the soulful character of historic diamonds.

At Oldmine & Co., every diamond is crafted with exceptional attention to detail. While advanced precision techniques ensure balance and brilliance, many of our signature cuts are intentionally created in free flow rather than strict engineering, allowing each stone to carry its own individuality and organic charm. We are especially known for rare champagne, cognac, and antique-toned lab-grown diamonds that are difficult to find in the modern market. Combining heritage craftsmanship with contemporary innovation, we create elegant, royal, and truly distinctive diamonds for collectors, designers, and fine jewelry houses worldwide.
