Antique Edwardian Platinum & Gold Engagement Ring | Circa 1900
A true antique diamond ring with over a century of history.
This exceptional 3 carat Old Mine Cut diamond ring was handcrafted at the turn of the 20th century, during the refined elegance of the Edwardian era, when jewellery was made slowly, by hand, and designed to last generations.
At its centre glows a magnificent 3.00 carat antique Old Mine Cut diamond — the romantic predecessor to the modern brilliant cut — prized today for its chunky facets, candlelight fire, and unmistakable character.
Unlike modern diamonds engineered for uniform sparkle, Old Mine Cuts were cut by eye and by hand.
Each one is unique.
Each one has a soul.
This one is extraordinary.
The Diamond
The centre stone displays everything collectors seek in a genuine antique Old Mine Cut diamond:
• High crown
• Small table
• Deep pavilion
• Broad, chunky facets
• Soft flashes of fire rather than sharp sparkle
• Beautiful kozibe reflections (a hallmark of authentic old cuts)
These stones were designed to glow under candlelight — producing a warm, romantic brilliance that modern cuts simply cannot replicate.
At 3 carats, this diamond has a commanding presence while remaining elegant and timeless on the hand.
No two Old Mine Cut diamonds are ever the same — making this ring completely one-of-a-kind.
The Setting
True to period craftsmanship, the diamond is secured in a platinum crown setting for strength and protection, paired with a warm yellow gold band for contrast and comfort.
Fine hand-set shoulder diamonds and delicate milgrain detailing reflect the meticulous artistry of Edwardian jewellers.
Details include:
• Platinum-topped prong setting
• Solid yellow gold shank
• Antique single-cut accent diamonds
• Hand engraving and milgrain work
• Total weight: 4.134 grams
• Original estate condition
Light, refined, and beautifully balanced — exactly how antique engagement rings were meant to feel.
