A Ceylon sapphire's price is driven by four things, roughly in this order: origin, treatment, colour and carat. Sapphire prices span one of the widest ranges of any gem, from about $200 per carat for a commercial heated stone to over $200,000 per carat for a museum-quality unheated Kashmir, and Ceylon sits firmly in the prestige tier, above Madagascar and below only Kashmir and Burma.
Because every stone is individual, no guide can quote an exact figure, but real benchmarks show how the factors stack up. (Rohan Sapphires is inquiry-first: we don't publish prices, but we will quote any stone on request.)
The four price drivers
- Origin, a lab-confirmed Ceylon report places a stone in the prestige tier (roughly $8,000–$40,000 per carat for fine material).
- Treatment, unheated stones (about 1% of the market) carry a 40–200% premium over equivalent heated ones.
- Colour, saturation and “life”; top designations like “Royal Blue” command the most.
- Carat, price per carat rises sharply with size; the 1–3 carat range is the heart of demand, at roughly 47% of sales.
Per-carat benchmarks
| Type | Indicative price / carat |
|---|---|
| Royal blue (fine) | $4,500–$15,500 |
| Cornflower blue | $2,320–$6,000+ |
| Padparadscha | $1,000–$6,000+ |
| Unheated 1 ct, with GRS report | $4,000–$12,000 |
| Unheated, over 10 ct | $50,000+ |
Why a certificate pays for itself
A recognised laboratory report adds an estimated 20–50% to value and protects you on the two facts that matter most, origin and treatment. On a fine sapphire, certification is not an optional extra; it is part of the price.
Are sapphires a good investment?
Fine sapphires have shown consistent annual price appreciation of roughly 6–8%, and unheated Ceylon stones with confirmed origin are increasingly treated as heirloom and investment assets. But condition, rarity and paperwork determine resale, so the sound approach is to buy the best single stone you can afford, with full documentation, rather than several lesser ones.
Spend on the things that hold value: confirmed Ceylon origin, unheated status, and the best colour you can afford, in that order. A report from a top laboratory protects all three.
Frequently asked questions
- How much is a Ceylon sapphire per carat?
- Fine Ceylon material commonly runs about $8,000–$40,000 per carat; royal blue roughly $4,500–$15,500, padparadscha about $1,000–$6,000+, with unheated stones over 10 carats exceeding $50,000 per carat.
- Why are unheated sapphires more expensive?
- They are rare, about 1% of the market, and entirely natural, commanding a 40–200% premium over equivalent heated stones.
- Does size increase the price a lot?
- Yes, price per carat rises steeply with size, so a fine 5-carat stone costs far more per carat than a 1-carat of equal quality.
- Are Ceylon sapphires a good investment?
- Fine stones have appreciated roughly 6–8% a year, and unheated certified stones are sought as heirloom assets, but rarity, condition and documentation drive resale value.
- Why doesn't Rohan Sapphires publish prices?
- We are inquiry-first: each stone is individual, so we quote on request once we understand what you are looking for.
