Old Mine Cut Diamonds: Why They’re Coming Back in Fashion — Especially in the Lab-Grown World
Old mine cut diamonds are quietly re-emerging as one of the most desirable engagement ring styles in Singapore — not because of nostalgia, but because lab-grown diamonds have finally made them practical, consistent, and accessible. Once confined to antique jewellery and estate pieces, the old mine cut’s soft geometry, deep sparkle, and romantic character are now being recreated with modern precision using lab technology.
At Diamond Ateliers, we’ve seen a clear shift: couples who want something personal, timeless, and visually distinctive are moving away from mass-produced brilliant cuts and rediscovering antique-inspired diamonds — without the ethical, pricing, or condition concerns of true antiques. This is where lab-grown old mine cuts excel, especially when paired with bespoke engagement rings.
What Is an Old Mine Cut Diamond?
The old mine cut is a historical diamond cut that originated in the 18th and 19th centuries. It predates the modern brilliant and was originally cut entirely by hand, long before precision machinery existed.
Key characteristics include:
- Squarish or softly rectangular outline (often mistaken for a cushion)
- High crown and small table
- Deep pavilion
- Large, open culet visible through the centre
The result is not sharp sparkle, but broad flashes of light — a glow rather than a glitter.
Why Old Mine Cuts Fell Out of Fashion
Old mine cuts were never designed for maximum light return. When modern cutting standards emerged in the early 20th century, diamonds became brighter, whiter, and more uniform. Brilliant cuts dominated because they:
- Maximised sparkle under electric lighting
- Were easier to standardise and mass-produce
- Appealed to global commercial jewellery markets
As a result, old mine cuts became rare — surviving mainly in antique rings with inconsistent proportions and limited availability.
Why They’re Back — And Why Lab-Grown Changed Everything
The revival of old mine cut diamonds has only been possible because of lab-grown diamond technology, which allows antique cuts to be recreated with modern control and reliability.
1. Precision Without Losing Character
Modern lab cutting allows us to recreate the charm of old mine cuts while correcting the extreme asymmetry that made antique stones risky purchases. You get:
- Balanced proportions
- Controlled depth
- Even facet patterning
The look remains antique — the performance is modern.
2. Ethical and Practical Sourcing
True antique diamonds come with unknown histories, variable condition, and limited sizing options. Lab-grown old mine cuts offer:
- Guaranteed ethical origin
- No mining impact
- Freedom to customise size, shape, and clarity
To understand how lab-grown diamonds are evaluated, explore our diamond grading guide.
3. Pricing That Finally Makes Sense
Natural antique old mine cuts are scarce — and priced accordingly. Lab-grown versions cost a fraction of the price while offering superior consistency. This allows couples to:
- Choose larger centre stones
- Invest more into bespoke setting design
- Avoid overpaying for rarity alone
Old Mine Cut vs Modern Brilliant: A Visual Difference
This choice is less about “better” and more about personality.
- Modern brilliant: sharp sparkle, symmetry, high contrast
- Old mine cut: soft glow, depth, visible facets, warmth

Why Singapore Couples Are Choosing Old Mine Cuts
In our studio, old mine cut lab diamonds are most often chosen by couples who:
- Want something visually different from standard mall jewellery
- Value craftsmanship and design story
- Prefer timeless style over trend-led sparkle
They pair exceptionally well with bespoke engagement rings, where the setting is designed around the stone — not the other way around.
Real Diamond Ateliers Example
One recent client chose a 2.20ct lab-grown old mine cut with a warm E colour and VS1 clarity, set into a hand-drawn bezel solitaire in 18K yellow gold. The stone appeared larger than its carat weight due to its spread, and the finished ring had a distinctly heirloom feel — without being fragile or outdated.
Is an Old Mine Cut Right for You?
An old mine cut is ideal if you value:
- Character over perfection
- Design over mass production
- A ring that feels personal, not generic
If maximum sparkle is your only goal, a brilliant cut may suit you better. But if you want warmth, depth, and individuality, old mine cuts deliver something modern diamonds cannot replicate.
