Introduction
When viewing a dazzling diamond or coloured gemstone, it is often the cut that makes it captivating. While carat weight, clarity, and colour all play a role in value, it is the cut that determines how light dances within the gem, creating brilliance, fire, and character. For clients exploring engagement rings or bespoke jewellery in Cape Town, understanding gemstone cuts is essential — they not only define beauty but also influence rarity and long-term value.
At Prins & Prins Diamonds, our gemmologists guide clients through these nuances, ensuring every choice reflects both style and legacy.
The Brilliant Cut
The round brilliant cut is the most iconic of all. Perfected in the early 20th century, this cut features 57 or 58 facets carefully angled to maximise light return. Its symmetry and precision ensure unmatched brilliance, making it the most popular choice for natural diamonds in engagement rings.
Why it matters:
- Maximum sparkle, ideal for those seeking fire and brilliance.
- Hides inclusions more effectively than other cuts.
- Timeless appeal — the brilliant cut remains a universal symbol of love and commitment.
At Prins & Prins, many of our most celebrated diamond engagement rings feature the brilliant cut, chosen for its ability to highlight the purity of natural gems.
Step-Cuts: Emerald and Asscher
Step-cuts offer a striking contrast to the brilliant. The emerald cut, with its elongated facets and open table, creates a hall-of-mirrors effect rather than fiery sparkle. Similarly, the Asscher cut, a square variation developed in the early 1900s, is admired for its Art Deco geometry and symmetry.
What sets them apart:
- They emphasise clarity over brilliance. Any inclusions are more visible, making quality paramount.
- Elegant, understated appearance — ideal for those who prefer sophistication over sparkle.
- Strong association with vintage-inspired and architectural design.
Step-cuts reflect refinement and require the discerning eye of a trusted jeweller to ensure that the gem’s quality justifies its visual openness.
The Rose-Cut
Dating back to the 16th century, the rose-cut features a domed top with triangular facets and a flat base. Unlike the brilliant cut, it has fewer facets and does not aim for maximum light return. Instead, it offers a subtle glow, resembling candlelight rather than modern brilliance.
Why clients love it:
- Antique charm — perfect for vintage or bespoke jewellery inspired by history.
- Unique personality — every rose-cut gem has a distinct character.
- Popular in modern revival pieces for those seeking individuality.
At Prins & Prins, rose-cut diamonds and coloured gems are often incorporated into bespoke designs where romance and heritage storytelling are central.
Other Notable Cuts
Beyond the classics, jewellery lovers can choose from a wide variety of cuts that suit different personalities and styles:
- Cushion Cut – Rounded corners and larger facets enhance brilliance with a soft, romantic appeal.
- Oval Cut – Elegant elongation with brilliance similar to the round. Flattering on the hand.
- Pear Cut – A teardrop silhouette symbolising tears of joy. Distinctive and eye-catching.
- Marquise Cut – Boat-shaped with a royal heritage, designed to maximise carat weight.
- Princess Cut – Square brilliant cut with sharp corners, modern and youthful in appearance.
Each cut brings a different aesthetic and emotional resonance, making the selection deeply personal.
Cut vs Shape
One of the most common confusions in jewellery buying is between cut and shape.
- Cut refers to how well the facets are angled, proportioned, and polished, which directly affects brilliance.
- Shape refers to the outline of the gem — round, oval, pear, etc.
A well-cut gem, regardless of shape, will reflect light beautifully. Conversely, a poorly cut gem can appear dull even if it has excellent colour and clarity. At Prins & Prins, our gemmologists explain this distinction clearly, empowering clients to make informed decisions.
Cape Town Context
Cape Town is a city where heritage meets modern luxury. Visitors often combine wine estate tours and Table Mountain hikes with a stop at our historic showroom in Huguenot House. Here, clients can explore a curated collection of diamonds and coloured gemstones, each carefully cut and certified.
What sets Prins & Prins apart is not just the selection, but the expertise offered. Whether a client is drawn to the brilliance of a round cut or the vintage charm of a rose-cut, our gemmologists provide guidance rooted in trust, heritage, and decades of experience.
Conclusion
The cut of a gem is its soul — it defines brilliance, character, and ultimately, how the jewel will be admired for generations. From the timeless round brilliant to the historic rose-cut, each cut tells its own story.
At Prins & Prins Diamonds in Cape Town, we believe that choosing the right cut is not simply about fashion. It is about ensuring your jewel represents authenticity, value, and legacy. Guided by our gemmologists, clients discover that the true beauty of a diamond or gemstone lies in more than sparkle — it lies in craftsmanship, heritage, and trust.
