How Much Is Lapis Lazuli Worth?
Lapis is one of the oldest gems traded by humans, and pricing it is refreshingly simple: the deeper and more even the blue, the more it’s worth.
Lapis lazuli is a rock, not a single mineral — mostly blue lazurite, with white calcite and golden pyrite mixed in. That mix is exactly what you’re judging. The most valued lapis is an intense, slightly violet “royal” blue with little or no white calcite, and just a fine sprinkle of pyrite. Too much calcite reads grey and cheap; clumps of pyrite that break up the blue also pull the price down.
What drives the price: depth of blue, then evenness
Colour is everything: a deep, saturated, even blue is the premium, and the finest comes from the Sar-e-Sang mines of Badakhshan, Afghanistan — the historic source for thousands of years. After colour, value depends on how evenly that blue covers the stone (minimal white patches) and on pyrite that’s fine and scattered like gold dust rather than blotchy. A smooth, glassy polish adds the finishing value.
Typical fair prices
Polished cabochons and beads, mid-2020s retail, natural and undyed. Lapis is usually sold per piece; per-carat figures help comparison.
| Grade | Typical | Fine / large |
|---|---|---|
| Pale / heavy calcite | <$1–$5/ct | $5–$15/ct |
| Medium blue | $5–$20/ct | $20–$40/ct |
| Good even blue | $20–$50/ct | $50–$90/ct |
| Fine Afghan “royal” blue | $50–$100/ct | $100–$200/ct+ |
Watch-outs
- Dyed lapis. Pale, calcite-rich lapis is often dyed to fake a deep blue. A cotton swab with a little acetone may pick up blue colour from dyed stones. Undisclosed dye is the most common lapis rip-off.
- “Reconstituted” or block lapis. Powdered lapis (or other minerals) bound with resin is sold as solid lapis. It looks suspiciously uniform and is worth far less.
- Dyed howlite, jasper or sodalite. Cheaper minerals are dyed blue and sold as lapis. True lapis usually shows some gold pyrite and an uneven, natural blue; sodalite tends toward a duller, more purplish blue with white veins.
- Pyrite that’s tarnished or blotchy. Fine gold flecks add appeal; large dull-grey patches or heavy clumps reduce value.
The International Gem Society ranks an even, deep violet-blue with minimal calcite highest, and details dyeing and reconstitution. The GIA describes lapis as a rock of lazurite, calcite and pyrite, with the finest historically from Afghanistan.
Buy lapis stated as natural and undyed
Our sister marketplace states colour grade, origin and whether a stone is natural and undyed — so you can price the blue with confidence.

Is pyrite in lapis a good or bad thing?
In moderation it’s a plus — fine gold flecks are part of fine lapis’s charm and help confirm it’s natural. It only hurts value when pyrite forms large dull patches or clumps that break up the blue.
How can I tell if lapis is dyed?
Dyed stones are often suspiciously even in colour with no pyrite. A cotton swab dampened with a little acetone may lift blue dye. Buying from sellers who state “natural, undyed” is the simplest protection.
Is Afghan lapis really the best?
Generally, yes. The Sar-e-Sang mines in Badakhshan have produced the deepest, most even blue for millennia. Chilean lapis tends to carry more calcite and reads paler, so it’s usually cheaper.
