Let's Start With the Truth
If you're buying a moissanite engagement ring expecting it to hold or increase its value as a financial asset, this guide will save you from a costly misconception. The resale market for moissanite is limited. Like most consumer goods — cars, electronics, clothing — a moissanite ring purchased at retail will sell for significantly less than you paid if you try to sell it privately.
But here's the fuller picture that most guides miss: the same is true of mined diamonds, lab-grown diamonds, and virtually every other category of jewellery. Understanding the resale reality across all three options — and what actually matters when you're making this decision — is what this guide covers.
The Resale Reality Across All Three Stone Categories
Moissanite resale value: Low. There is a small secondary market (Gumtree, Facebook Marketplace, specialist resale platforms), but prices are typically 20–40% of original retail. Moissanite is produced at scale in laboratories — supply is consistent, which means secondary market prices remain compressed.
Lab-grown diamond resale value: Also declining significantly. Between 2021 and 2025, lab-grown diamond retail prices fell by 50–70% as production capacity expanded globally. Rings bought at 2021–2022 prices are being resold at a fraction of their purchase price. The secondary market exists but is increasingly challenging for sellers.
Mined diamond resale value: Better established secondary market, but still disappointing for most retail buyers. The typical retail-to-resale loss on a mined diamond engagement ring is 30–60% of purchase price. The "diamonds hold their value" narrative applies primarily to exceptional investment-grade stones (3ct+, D/IF or better, GIA-certified) — not to the 1ct F/VS2 stone that most people actually buy.
The uncomfortable conclusion: No engagement ring category is reliably a financial investment for the typical buyer. Anyone telling you otherwise — regardless of stone type — is either misinformed or selling something.
Why People Ask About Resale Value (And What They're Really Asking)
Most people who ask about moissanite resale value aren't planning to sell the ring. They're really asking one of two things:
"Is moissanite a 'lesser' choice that I'll regret?" The answer is no — if moissanite is chosen intentionally and with full understanding of what it is. It's not a compromise; it's a different stone with different properties. Many couples choose moissanite specifically because they prefer its optical character, its ethical origin, and what its price point allows them to do with the rest of their budget.
"If our circumstances change, can I recover some value?" Yes, partially — as you can with any jewellery. The gold in your ring retains commodity value regardless of stone type. The stone will sell at a discount, but it will sell. And Heritage & Co.'s solid gold settings can be repurposed or recast if a ring is ever retired.
The Real Value Calculation for Moissanite
Here is the framing we think is more useful than resale value:
Cost per year of wear. A moissanite ring bought at R20,000 that is worn daily for 30 years costs approximately R667 per year — less than R2 per day. Over that 30 years, it will be polished, admired, photographed thousands of times, and worn through every significant moment of a marriage. The "resale value" becomes almost irrelevant against this context.
Contrast this with spending R80,000 on a mined diamond ring on the basis of "investment value" — the arithmetic doesn't support that decision even with a more favourable secondary market.
How to Maximise the Resale Position of Any Ring
If resale matters to you, here are the factors that most influence a ring's secondary market value:
Stone certification: An uncertified stone is essentially unsellable on the secondary market at any meaningful price. A GRA-certified moissanite or IGI/GIA-certified lab diamond has verifiable quality claims that a buyer can trust. Always buy certified.
Metal quality: Solid gold (9k, 14k, 18k) retains commodity value. The gold in a Heritage & Co. ring can always be melted and refined for its gold content. Gold-plated rings have near-zero metal resale value.
Condition: A well-maintained ring in excellent condition commands significantly more on resale than one with bent prongs, scratched metal, and a cloudy stone. The annual professional clean and prong-check we recommend isn't just maintenance — it's protecting whatever resale value exists.
Documentation: Certificate, original receipt, box and packaging, any warranty documentation. Keep everything. It makes a private sale significantly easier and supports a higher price.
Heritage & Co.'s Position on This
We are transparent about moissanite resale. We don't tell customers that moissanite is an investment, because it isn't — and neither is any other engagement ring stone for most buyers. What we tell customers is this: we build rings that are worth wearing every day for decades, made from solid gold with certified stones, at a price that doesn't require significant financial strain going into a marriage.
A ring that costs you R18,000 instead of R80,000 for equivalent visible quality means R62,000 that stays in your life — for a home deposit, a honeymoon, your first year of mortgage payments, or simply financial breathing room. That is real, tangible value. We think that matters more than an uncertain secondary market.

Frequently Asked Questions
Can I upgrade my moissanite to a diamond later? Yes. Heritage & Co. offers an upgrade service — the existing gold setting can often be retained and the stone replaced. Contact us to discuss the specifics of your ring and your upgrade goals.
Where can I sell a moissanite ring in South Africa? Gumtree, Facebook Marketplace groups, specialist online jewellery resale platforms, and some pawnbrokers. Set expectations: you will not recover retail price. Price it at 25–40% of original retail for a realistic sale.
Does moissanite become less valuable over time like cars depreciate? The stone itself doesn't depreciate — its physical properties are permanent. What changes is the secondary market price, driven by supply dynamics and consumer demand, not by the stone's actual quality.
