Custom Engagement Rings — Designed Around You
Every great love story deserves a ring as unique as the people in it. That's why every custom engagement ring we create begins with a conversation — not a catalogue. You tell us what you imagine. We bring it to life.
Whether you're dreaming of a classic solitaire, a vintage-inspired halo, or something entirely original, our process is the same: you choose the diamond first — natural or lab-grown, any shape, any size — and we build the setting around it. This means the ring fits your stone perfectly, your style exactly, and your budget honestly.
All our loose diamonds are certified by GIA, IGI, or HRD — internationally recognised laboratories — so you know exactly what you're getting. And because we're factory-direct, your ring is handcrafted in our Johannesburg workshop, not mass-produced in a foreign factory.
Why Diagem custom engagement rings start at the right price: We're diamond manufacturers, not retailers. You pay for the stone, the metal, and our craftsmanship — never for a showroom, a commission, or a brand name.
Our Bespoke Diamond Design Process
Our bespoke diamond design service turns your ideas into a finished ring — no design fees, no hidden costs, no pressure. Here's how it works:
1. Consult
Chat with David about your vision — stone type, style, budget, timeline. In person, by phone, or on WhatsApp. 30–60 minutes, no obligation.
2. Design
David consults with you to understand your style. Share a photo or describe your ideal ring — we take it from there and provide a detailed quote.
3. Craft
Hand-finished in our Johannesburg workshop. We send photos at every milestone. Delivery within 2 weeks.
The best part? Our bespoke design service is completely free when you buy your diamond from us. You only pay for the stone and materials — never for our design time. Start your design today.
Choose Your Diamond — Natural or Lab-Grown
Your engagement ring starts with the diamond. We offer both certified natural diamonds and lab-grown diamonds, each with its own strengths. Not sure which is right? Read our natural vs lab-grown guide.
- Natural diamonds: Mined, rare, timeless. Ideal for investment heirloom pieces.
- Lab-grown diamonds: Identical in every way — chemistry, brilliance, hardness — at 50-70% less cost. Go bigger or save the difference.
- All certified: Every diamond comes with a GIA, IGI, or HRD certificate. No exceptions.
Engagement Ring Pricing — What to Expect
Engagement ring prices in South Africa vary widely depending on the diamond, metal, and complexity. Here's a realistic guide:
- Entry-level (lab-grown diamond): From R8,000 – R20,000 for a beautiful, certified 1ct+ ring
- Mid-range (natural diamond): R25,000 – R80,000 for a quality natural 0.5ct–1ct diamond in a custom setting
- Premium (larger natural / fancy colours): R80,000+ for investment-grade stones, coloured diamonds, or complex multi-stone designs
- Setting only (your diamond, our design): From R3,500 for a simple solitaire setting

Engagement Ring FAQ
How long does a custom engagement ring take?
Typically 3–4 weeks from design approval to delivery. If you need it sooner, let us know — we can often accelerate to 2 weeks for simpler settings.
Do I have to visit your showroom?
We're online-only — no physical showroom. You can design your entire ring from anywhere in South Africa. David does consultations by phone, WhatsApp video, or in person at our Johannesburg workshop by appointment.
Can I see the diamond before buying?
Absolutely. We send detailed videos and 360° imagery of every diamond. You can also view it in person at our Johannesburg workshop.
What if I already have a diamond?
Great — we can design a setting around your existing stone. We've done this for family heirloom diamonds, inherited pieces, and stones bought loose elsewhere. Our bespoke service works with any certified diamond.
Do you deliver across South Africa?
Yes — we deliver insured, tracked, and signed-for anywhere in South Africa. Cape Town, Durban, Pretoria, Stellenbosch, and beyond.
