You're about to spend anywhere from R17,000 to R30,000 or more on a ring she'll wear every day for the rest of her life. The decision matters. This guide covers everything you need to know before you buy — stone type, certification, metal, size, and budget — so you can walk away confident.
Step 1: Choose Your Stone Type
The two best options for engagement rings in South Africa right now are moissanite and lab-grown diamonds. Both are real, both are beautiful, and both are certified. Here's how they differ:
| Feature | Moissanite (GRA) | Lab Diamond (IGI) |
|---|---|---|
| Brilliance | Higher refractive index — more fire | Classic diamond brilliance |
| Hardness | 9.25 Mohs — extremely durable | 10 Mohs — hardest natural material |
| Certification | GRA certified, D/VVS1 | IGI certified, D colour, VVS1 |
| Price range | R19,500–R39,000 | R17,000+ |
| Chemical identity | Silicon carbide | Carbon — identical to mined diamond |
Bottom line: If budget is a priority, moissanite gives you a larger, more brilliant stone for less. If diamond certification matters to her, lab diamond is the answer — at a fraction of the cost of a mined stone.
Step 2: Understand the 4Cs (Simplified)
All Heritage & Co. stones are pre-selected to the highest grades, so you don't need to become a gemologist. But here's what the grading means:
- Cut — The most important factor. Determines how the stone catches and reflects light. All our stones are Excellent cut.
- Colour — D is colourless (best). Our moissanite and our lab diamonds are D colour as standard.
- Clarity — VVS1 means very very slightly included — invisible to the naked eye. Our lab diamonds and our moissanite are VVS1 as standard; some lab diamond designs also offer F colour, VS2 clarity at a lower price.
- Carat — Weight of the stone. Bigger isn't always better — a well-cut smaller stone outshines a poorly cut larger one.
Step 3: Choose Your Metal
All Heritage & Co. rings are solid gold — no plating, no base metal. Here's what the options mean:
- 10K gold — 41.7% pure gold. More durable, lower price. AETERNA and CLARITAS collections.
- 14K gold — 58.5% pure gold. The global sweet spot for engagement rings. AETERNA and CLARITAS collections.
- 18K gold — 75% pure gold. Richest colour, most prestigious. CLARITAS collection (also offered in 10K and 14K).
Available in yellow gold, white gold (rhodium plated), and rose gold depending on the style.
Step 4: Choose Your Ring Style
The setting determines the personality of the ring:
- Solitaire — One stone, clean and timeless. The most classic choice.
- Halo — A circle of accent stones around the centre. Makes the stone appear larger.
- Pavé — Small diamonds or moissanites set along the band. Maximum sparkle.
- Three-stone — Centre stone flanked by two smaller stones. Symbolic: past, present, future.
Step 5: Know Her Ring Size
South African ring sizes use the AU/UK scale. US numbers and millimetres are also common. A standard conversion gives US 6 as 16.5 mm inside diameter (UK L½), US 7 as 17.3 mm (UK N½) and US 8 as 18.1 mm (UK P½). If unsure, a ring she already wears on that finger is the best guide, and we confirm the size before production. Fingers shrink in cold weather, so add half a size to a winter measurement.
