The diamond trade tends to move when it is forced to. We would rather move proactively. Every commitment below was taken on because it was possible and because it was right, not because any standard besides our own demanded it of us.
We are not finished. We review this every year and look for the thing we are not yet doing, because staying ahead of where the industry is heading is not a position you hold, it is a decision you keep making. If there is something you think we should be doing, tell us.
A diamond passes through a small number of hands before it reaches you. Most dealers can account for one or two links in that chain. Because the cutting is ours and has been for three generations, we can account for four, and we can show you the paperwork behind each one.
Our cutters are paid 50 percent above the market rate in Surat. Not as a gesture, but because precision cutting is skilled work and the people doing it are the reason our stones look the way they do.
Why it holds Our cutters stay. In an industry defined by turnover, the senior hands have been here long enough to have trained the people sitting beside them.In 2026 we measured the power drawn at all three of our locations and matched every megawatt hour with certified renewable generation. Eighty-four megawatt hours of wind and solar, purchased and retired in our name.
Why it holds Solar and wind energy purchased through a certified B Corporation, and retired so that no other party can claim it.Every parcel of rough we buy moves through the Kimberley Process, sealed and accompanied by a uniquely numbered certificate of origin. We buy exclusively from zones we know are non-conflict, and the same certificate is what makes origin reporting possible downstream.
Why it holds The guarantee is written on every invoice we issue, under the industry System of Warranties. It travels with the stone.Selected stones carry a GIA Diamond Origin Report, which states the diamond's country of origin on the report itself. GIA analyses the rough before it is polished, then matches the finished stone back to that rough using markers recorded at the outset.
Why it holds A dealer who buys polished goods cannot obtain one. The rough has to reach the laboratory before it is cut, and we buy ours direct from the mining companies and cut it in our own facility.We reviewed a full year of power consumption at every location we operate- our cutting facility in Surat, our office in Mumbai, and our headquarters in Los Angeles. In 2026 we purchased and retired 84 megawatt hours of certified solar and wind renewable energy certificates through a certified B Corporation, one of the longest operating renewable energy providers in the United States. Retired in our name, they cannot be counted by anyone else.

The Surat cutting facility, the Mumbai office, and the Los Angeles headquarters. Every place we operate, with nothing left out.
We are continuing the programme into next year and expect coverage to grow with the business rather than lag behind it.
That is what we pay the cutters at our benches, and it is the most direct answer we can give to why our stones look the way they do. Surat cuts most of the world's diamonds, and it is an industry built on speed. Work is handed out by the parcel, pay rises and falls with the flow of rough, and cutters move between factories chasing it.
Precision cutting does not survive that. An Old Mine cut is not a shape you programme into a machine, it is a series of judgments made by a person reading a specific piece of rough, and getting it wrong costs more than the time saved. Paying well above the going rate is how we keep people who can make those judgments, year after year, at the same benches.
It is also why we can take on stones other houses turn away. Volume cutting and precision cutting are two different trades, and only one of them can be bought cheaply.
"A cutter who has spent twenty years reading a specific kind of rough is the reason we can take on stones other houses turn away."
What our cutters are paid against the going rate for equivalent work in Surat, the city that cuts most of the world's diamonds.
Three generations of the same family have run these benches, and the sourcing relationships behind them go back further still.
We employ our cutters directly rather than subcontracting to third-party factories, which is what makes any of this ours to answer for.
Conflict-free is the floor, not the achievement. Every parcel of rough we buy moves through the Kimberley Process, and the guarantee is written into every invoice we issue. We have held that line since long before it was a marketing category.
Scientific origin is where the real progress is. The GIA Diamond Origin Report states a diamond's country of origin on the report itself, confirmed by analysis rather than by a chain of documents. GIA records the rough before it is polished, then matches the finished stone back to that rough using markers identified at the start.
That sequence is the whole point. The rough has to reach the laboratory sealed, before anyone cuts it, which means a dealer buying finished goods can never obtain one. We buy our rough direct from the mining companies and cut it in our own facility, so the door is open to us and closed to most of the trade.
Some of what we carry is antique and estate material, cut generations before us by hands we will never know. We tell you which stones those are, because a diamond with a hundred years behind it is worth more when you know that is what you are holding.
The GIA Diamond Origin Report names the country a diamond came from, printed on the report alongside a full 4Cs assessment and a plotted diagram of the polished stone.
We purchase rough directly from mining companies rather than through the polished market, which is what keeps the chain short enough to document from the ground to the bench.
Eligibility depends on the rough passing through GIA analysis before polishing. GIA then uses markers and data taken from that rough to match it scientifically to the finished stone.
Rough parcels travel sealed, with a uniquely numbered certificate of origin and the mining company invoice. That documentation is a submission requirement for origin reporting, not a separate exercise.
Four commitments is where we are, not where we are stopping. Some of what follows is already underway and some of it is waiting on better data. If your client or your compliance team needs documentation we have not listed here, ask us, because that request is usually what moves an item from the right column to the left.
Work already started, with results we expect to publish on this page as they are documented rather than announced in advance.
Longer horizon work that needs measurement before it needs a claim. We would rather bring you the number than the intention.
Nothing on this page rests on our word alone. Each commitment is backed by certification issued by an independent body, and we are glad to walk any customer or trade partner through the detail.

If you would like to know more about our sustainability practices, or need documentation for a client or a compliance review, please email us and we will take you through it.
The trade is increasingly being asked to answer for where a stone came from and who handled it. We would rather give you documentation you can forward than assurances you have to repeat. Trade accounts are open, and we are happy to go further into any of this than the page does.
