Eternity Rings in South Africa: Full vs Half Eternity Price Guide (2026)
Eternity rings in South Africa typically range from R45,000 to R250,000 depending on total carat weight, metal, and full versus half setting. Prodiam produces eternity rings in-house at wholesale margin, with a 1.50 carat total weight half-eternity in platinum landing around R55,000-75,000 (versus R95,000-130,000 retail tier). Buyers choosing eternity rings should plan for the resizing limitation: full-eternity rings typically cannot be resized without rebuilding the setting, while half-eternity rings can.
Eternity Ring Pricing at a Glance (2026)
What an eternity ring is and when to buy one
An eternity ring is a band set with a continuous line of equally-sized diamonds (or other gemstones) around the ring shank. Traditionally given at a milestone anniversary (commonly 10th, 25th, or 50th) or at the birth of a child, the ring symbolises continuous commitment, hence the name.
The two main variants are full eternity (diamonds set 360 degrees around the band) and half eternity (diamonds across the front half only, plain metal around the back). Full eternity is more striking but cannot easily be resized once made, because resizing breaks the diamond line. Half eternity sacrifices visual coverage but allows future resizing as finger size changes over time.
Most South African buyers choose half eternity for the practical resizing advantage, with full eternity reserved for milestone anniversaries where the gift is fixed-purpose and resizing is unlikely. Stone count typically ranges from 15 to 35 diamonds, total carat weight from 0.50 to 2.50.

Where to source eternity rings in SA
Prodiam: in-house eternity ring manufacture at wholesale margin
Prodiam produces eternity rings in their Bedfordview workshop using GIA-graded melee diamonds matched for colour and clarity tolerance across the full set. Customers can specify TCW, metal (18ct white gold, platinum, occasionally yellow gold), full or half eternity, and prong style.
Pricing reflects wholesale-to-public margin on every component: stones at trade tier, in-house labour at workshop margin, no retail showroom premium. On a 1.50ct half eternity in platinum, Prodiam typically lands R55,000-75,000 versus the same ring at premium retail R95,000-130,000.
Lead time is typically three to four weeks for a custom commission. Prodiam also keeps in-stock options for buyers who need a quicker turnaround, particularly around anniversary windows in October to December.
Premium retail (Jack Friedman, Mark Solomon, Browns)
Established premium retail eternity ring lines exist at Jack Friedman, Mark Solomon, Browns, and Charles Greig at the upper end. Pricing typically lands 60 to 80 per cent above Prodiam wholesale on equivalent grade and TCW. The trade-off is the showroom experience and the brand association.
Half vs full eternity: practical decision
Full eternity is visually superior but practically inflexible. Once the diamonds are set 360 degrees around the band, resizing without breaking the diamond line is essentially impossible; future size changes require rebuilding the setting from scratch. For buyers in their twenties or thirties whose finger size may change over decades, this is a real long-term cost.
Half eternity covers the front half of the ring (the visible part) and leaves the back half plain. Visually it presents identically when worn (the back of the ring is hidden against the palm). Practically it can be resized cleanly. Most SA buyers choose half eternity for this reason. Full eternity remains the right call for milestone anniversaries (50th, 25th) where the recipient is older, finger size is stable, and the gift is symbolic-fixed.
Guidance and sources
Eternity ring rules: 5 practical points
- Choose half eternity unless finger size is genuinely stable. Resizing limitation is real on full eternity.
- Specify GIA grading on melee, or at minimum colour and clarity tolerance. Mixed-quality melee is a common quiet downgrade in retail eternity rings.
- Match the engagement ring metal where worn together. Mixing 18ct white gold with platinum on the same finger creates uneven wear over time.
- Confirm prong type and security. Shared-prong settings are more delicate than full-bezel; ask about repair history on the dealer's past commissions.
- Verify Diamond Dealers Club of South Africa membership of the manufacturer.
Frequently Asked Questions
What is the difference between full and half eternity rings?
Full eternity has diamonds set 360 degrees around the band; half eternity has them across the front half only. Full is visually superior but cannot be resized without rebuilding; half can be resized.
When do you traditionally give an eternity ring?
Most commonly at a milestone wedding anniversary (10th, 25th, 50th) or at the birth of a child. Some couples buy paired with the engagement ring upgrade.

At Prodiam wholesale: half eternity 1.50ct platinum R55,000-75,000. At premium retail: R95,000-130,000.
Can I customise stone count or shape?
Yes. Prodiam runs custom eternity commissions from 0.50ct TCW (small stones, often 15+) up to 3.00ct+ (larger stones, smaller count). Round brilliant is most common; cushion and emerald-cut eternity rings are available on request.
How do I check that a South African diamond dealer is legitimate?
