A Ceylon sapphire passes through six to nine hands between the pit and a buyer's finger. Here is the real supply chain, traced through one stone we currently sell, and how Crestonne shortens it.

A Ceylon sapphire passes through six to nine hands between the pit it comes out of in Ratnapura and the finger of the person who eventually wears it. The traditional Sri Lanka sapphire supply chain runs: pit miner, mine-side aggregator, Ratnapura dealer, Colombo specialist, cutter, polisher, lab, export agent, retailer. Crestonne's chain runs three: miner via the aggregator we work with, our cutter in Beruwala, then us. This post traces one specific stone, The Meridian, through every step of that journey, with the dates, the prices, and the handoffs.
"Mine to market" is the most overused phrase in the colored stone trade. Almost every direct mine to market sapphire brand uses some version of it, and almost none of them mean exactly the same thing.
The honest definition is this: a documented chain of custody from a licensed Sri Lankan mining permit through cutting and certification to the final buyer, with no anonymous intermediaries. It does not mean the brand bought the stone from the miner with their own hands. That is not how Sri Lankan artisanal mining actually works, and any brand claiming otherwise is either stretching the truth or describing an unusual one-off transaction.
The reason is structural. A pit miner in Ratnapura works a six-by-six meter shaft with three or four laborers, washes the gravel by hand in the river, and sees maybe one stone above two carats per month if the pit is productive. That miner does not have an export license, does not speak English, does not have the bank infrastructure to invoice a foreign buyer, and cannot afford to hold inventory waiting for the right deal. They sell to a mine-side aggregator the same day the stone is washed clean, for cash, at a price that lets them eat that week. We covered the mining stage in detail in how Sri Lankan gems are mined.
What a genuine short supply chain looks like is different. It is one where each handoff between the pit and the final buyer is named, dated, and priced, and where the brand can show you the dealer they bought from, the cutter they used, and the lab that certified the stone. Not less than three steps. Just no anonymous steps.
Before walking through Crestonne's chain, here is the full traditional version. Most jewelry-chain sapphires in your local mall have travelled this exact path:
Add it all up and the rough that paid the miner $400 lands on a retail shelf at $4,000 to $7,000 finished and mounted. Some of that is real value-add: cutting transforms the stone, certification underwrites trust, retail provides the buyer experience. But a meaningful slice is friction, and friction is what shortening the chain is supposed to reduce.
The chain we operate has three named handoffs between pit and buyer.
1. Mine-side aggregator. We work with one aggregator family near Pelmadulla, a short drive south of Ratnapura. We have been buying from them since 2022. They sort and price their weekly stock, we visit roughly every six weeks, and we buy in batches of three to twelve stones depending on what they have. We see the rough before they have shown it to other dealers, which is a privilege earned over years of consistent business.
2. Our cutter in Beruwala. A second-generation lapidary working in a family workshop on the coast. He has cut roughly 80 percent of the finished stones in our collection. We discuss the cutting plan together for each stone, weigh the trade-offs between color retention and ideal proportions, and agree on a target finished carat weight. The full sapphire traceability record we keep for each stone includes his cutting notes and a video of the rough being marked.
3. The lab. Every stone above one carat goes to SSEF or Lotus Gemology in Switzerland or Bangkok respectively. Smaller stones go to GIA in Bangkok. We never list a stone without the report in hand.
That is the full chain. There is no Colombo specialist link, no export agent (we handle the documentation ourselves), and no retailer markup because we are the retailer. The two removed links are roughly where 40 percent of the traditional retail premium lives.
The cleanest way to show what a short chain actually produces is to trace one stone all the way through. The Meridian is the unheated royal blue cushion currently listed in our collection, and here is its full provenance.
October 2025, Pelmadulla. A 4.84 carat rough Ceylon sapphire is washed out of a pit on land owned by a smallholder family who lease mining rights to a four-person mining team. The rough goes to our aggregator the same afternoon for the equivalent of $310. We see a photograph that evening via WhatsApp.
Late October 2025, Pelmadulla. We visit the aggregator the following week. The stone is sitting in a small folded paper packet labeled in Sinhalese with the pit reference and date. The rough has good color visible through the cleaning solution, no obvious black inclusions, and a shape that suggests a cushion or oval cut. We agree a price of $740 and pay in Sri Lankan rupees. We photograph the rough on a calibrated background and weigh it on the aggregator's scale.
November 2025, Beruwala. The rough goes to our cutter. We sit with him for an hour discussing the plan. The stone has a slight zoning band that runs at a thirty-degree angle through the centre. Cutting along the band would yield a 2.6 carat stone with visible zoning. Cutting against it would yield 2.3 carats with the zoning effectively hidden inside the pavilion. We choose the smaller, cleaner version. He marks the stone with a fine-tip pencil. We photograph it before cutting begins.
November to December 2025, Beruwala. The cutter works the stone over roughly twelve days, with the bulk of the time on initial shaping and the table facet. The final piece comes off the wheel at 2.31 carats, a cushion measuring 7.9 by 7.4 by 4.8 millimeters.
January 2026, Bangkok. We submit the stone to Lotus Gemology with a brief on origin. The report comes back four weeks later: Sri Lankan origin confirmed, no indications of heating, transparent royal blue with a slight violet modifier, eye-clean. The report references the spectroscopic and inclusion data they used to reach those conclusions.
February 2026, Colombo. We photograph the finished stone on the same calibrated background we used for the rough, against a black velvet tray, and again held in tweezers under standardized lighting. The stone, the report, the rough photograph, and the cutter's notes go into our internal provenance record.
March 2026, online. The Meridian goes live on the Crestonne site at $7,200, which is roughly 35 percent below the retail price comparable stones command at major Western jewelers. The price reflects fewer markups, not lower quality.
This is what a documented Sri Lanka sapphire supply chain actually looks like, end to end. Five named handoffs over six months, with each step photographed or recorded.
For every stone in our collection, the traceability file contains:
The point of the record is not vanity. It is so that the buyer, or a resale buyer ten years from now, can trust the stone without having to verify everything from scratch. A clean traceability file is what makes a sapphire genuinely investment-grade in the long-hold sense, and we walked through that math in the Ceylon sapphire investment guide.
It also makes our ethical sourcing claims auditable rather than aspirational. We describe what ethical sourcing means in practice in our piece on ethically sourced Ceylon sapphires, and the traceability file is the receipt behind that claim. We can show you exactly which pit, which aggregator, which cutter, and which lab.
Three things follow from a short, documented chain.
Price. You pay roughly what you would pay through one or two layers of dealer markup, not five or six. On stones above two carats, the saving is twenty to forty percent versus equivalent stones at chain retailers.
Trust. Every claim we make about origin, treatment, and ethics is backed by a record we can show you. There is no "we trust our supplier" link in the chain where the audit trail goes dark.
Resale credibility. Years from now, when you (or the next owner) wants to sell, the provenance file travels with the stone. A documented chain is a meaningful resale asset on its own, separate from the stone itself.
Behind all of it is a fairly simple thesis. The Sri Lanka sapphire supply chain has worked the same way for two hundred years. We are not trying to reinvent it. We are trying to make it shorter, more transparent, and easier for an end buyer to trust. That is the entire business.
If you want to start with a stone in our collection, the current listings are linked. If you want something specific, larger, or in a particular color that is not currently in stock, our custom sourcing service is how we go back into the aggregator network with your brief in hand. Either way, the same chain applies. Three handoffs, fully documented, from the pit to the stone in your hand. The full Crestonne story is the longer version of why we built it that way.
