A Few of Our Loved Engagement Rings
Every engagement ring is made to order. These are starting points. Yours is designed around her. Tap any ring to view it.
Custom, not off-the-shelf
A custom ring costs the same or less than a retail one, because there is no showroom markup between the goldsmith and your hand.
Off-the-shelf
- Designed for the widest possible taste, not for her.
- You accept whatever stone grade is in stock.
- Retail markup of 200 to 400 percent over cost.
- What you see in the case is what you get.
Custom by Moissanite by Design
- Designed around her style, her hand, her story.
- You choose the certified stone. GRA or IGI included.
- One all-in price before we start. Nothing hidden.
- Full 3D render for your approval before we craft.
The Brilliance of a Diamond. A Fraction of the Price.
Moissanite is a lab-created gemstone with a refractive index higher than a diamond. It catches the light in a way that turns heads. It is one of the hardest stones on earth, rated 9.25 on the Mohs scale, and it will not cloud or scratch over time.

Before you begin
Custom moissanite engagement rings start from R10,000. Lab diamond rings start from around R18,000. All pricing is fully inclusive: stone, setting, metal, 3D design and delivery. No add-ons at the end.
Yes, always. We produce a full 3D CAD render and send it to you for approval before a single gram of metal is used. You can request changes. Nothing goes into production until you are completely happy.
Yes. We deliver securely to all provinces, from Johannesburg and Cape Town to Durban, Pretoria, Gqeberha, Bloemfontein, East London and everywhere between. International delivery is available on request.
Yes. Moissanite scores 9.25 on the Mohs hardness scale, well above what daily wear needs. It produces more fire than diamond, comes with GRA certification, and costs far less, so your budget stretches to a larger stone or a more intricate setting.
That is exactly where most clients start. You do not need a design. Tell us about her, her style and what she loves. Share a photo of jewellery she owns if you have one. We guide the design from there.
Yes. One complimentary resize is included within 6 months of delivery. Some setting styles limit how many sizes can be adjusted, and we advise on this when confirming production.
