A diamond engagement ring is one of life’s most meaningful purchases — a symbol of love, intention, and artistry. Choosing the right one is both a personal and informed decision, blending emotion with craftsmanship. With so many shapes, settings, and specifications to consider, the process can feel overwhelming — but with expert guidance, it becomes a journey of discovery.
At Prins & Prins Diamonds, our gemmologists and master goldsmiths in Cape Town’s historic Huguenot House have been helping clients find (and design) their dream engagement rings for over forty years. Whether you’re drawn to timeless classics or modern designs, this guide will help you understand the essentials — from diamond shape and carat weight to setting style and certification — so you can choose a ring that reflects both your love and your legacy.
Step One: Choosing the Right Diamond Shape
The diamond’s shape defines the character of your ring. It determines how light dances through the facets and how the ring feels on the hand. Each shape carries its own charm and symbolism.
- Round Brilliant – The most popular and classic cut, prized for its unmatched sparkle.
- Oval – Elegant and elongated, offering brilliance with a slightly vintage appeal.
- Emerald – Step-cut facets reveal clarity and sophistication, perfect for those who love understated glamour.
- Princess – Sharp, modern lines give this cut its contemporary allure.
- Pear and Marquise – Distinctive shapes that elongate the finger, reflecting individuality.
- Cushion – Romantic and timeless, with soft corners and a luxurious glow.
When choosing a shape, consider the wearer’s personality and lifestyle. A round or cushion-cut diamond suits those who love classic elegance, while an emerald or pear shape may appeal to someone with distinctive taste.
Every shape can be custom-set by our designers at Prins & Prins to complement the wearer’s style and daily life — ensuring beauty without compromise.
Step Two: Understanding Carat Weight and Balance
A diamond’s carat weight (ct) refers to its size, but it is only one part of its value. Two diamonds of the same carat weight may look entirely different depending on their cut and proportions.
Rather than focusing on size alone, consider balance — a diamond that is well-cut will often appear larger and more radiant than a heavier one that is poorly proportioned.
At Prins & Prins, our gemmologists guide clients in finding the ideal combination of carat, cut, and budget to maximise brilliance. Each certified natural diamond is carefully chosen for its light performance and visual harmony.
Whether you’re drawn to a delicate solitaire or a statement halo, the goal is the same: a diamond that captivates in every light.
Step Three: Selecting a Setting Style
The setting is more than a frame; it protects the diamond and defines the ring’s aesthetic. Prins & Prins crafts every ring in-house, allowing each design to be as unique as the person who will wear it.
- Solitaire: Classic and timeless — a single diamond taking centre stage.
- Halo: A circle of smaller diamonds surrounding the main gem, adding brilliance and a vintage touch.
- Bezel: A sleek metal rim encases the diamond, offering security and modern simplicity.
- Three-Stone: Symbolising past, present, and future — a meaningful and elegant choice.
The choice of metal also influences the final look. Options include platinum for durability and cool lustre, or 18K yellow, white, or rose gold for warmth and contrast.
Inside the Prins & Prins workshop, located beneath the old wine cellar of Huguenot House, each ring is handcrafted by skilled goldsmiths using both traditional techniques and modern precision. The result: heirloom-quality craftsmanship that endures a lifetime.
Step Four: Prioritising Certification and Provenance
A diamond’s brilliance is only part of its story. True confidence comes from certification — official documentation verifying authenticity, quality, and ethical sourcing.
Every certified diamond is evaluated by an independent gemmological laboratory such as the Gemological Institute of America (GIA) or the European Gemmological Laboratory (EGL). These certificates detail the Four Cs — cut, colour, clarity, and carat weight — providing an accurate profile of each gem.
At Prins & Prins Diamonds, we work exclusively with natural, certified diamonds, ethically sourced and conflict-free. Clients are invited to examine their chosen diamond under magnification, compare certificates, and learn how each characteristic influences value and beauty.
This transparency is part of what makes Prins & Prins a trusted name in South African gemmology. Certification protects your investment and ensures your engagement ring’s story is one of integrity from the Earth to your hand.
Step Five: Bespoke Design — Bringing Your Vision to Life
While pre-designed rings are beautiful, nothing compares to the intimacy of a bespoke creation. Our in-house designers transform personal inspiration into wearable art — from sketches and CAD renderings to handcrafted perfection.
Clients can select their diamond, setting, and precious metal, then collaborate with our goldsmiths to bring their dream to life. Each bespoke engagement ring reflects individuality, heritage, and emotion — designed not just for a proposal, but for a lifetime.

Step Six: Finding Meaning Beyond the Sparkle
Choosing a diamond engagement ring is ultimately about connection — between two people, and between art and authenticity. A well-chosen ring embodies that harmony: a gem born of nature, shaped by human skill, and cherished for generations.
At Prins & Prins Diamonds, we believe education empowers love. Every consultation is an opportunity to learn about diamonds, design, and heritage — ensuring each client makes an informed, confident choice.
When beauty meets knowledge, the result is more than jewellery — it’s a legacy of trust, craftsmanship, and emotion set in precious metal.
