Minerals
MultiGen Minerals sources and sells physical mineral assets, with the origin and condition of every item disclosed before purchase. Colombian emeralds are the first line. Oil and gold follow.
Live now
Colombian Emeralds
Rough specimens, loose cut stones, finished jewelry and trade parcels — bought in Boyacá, graded in daylight, shipped from the United States. Origin mine and clarity enhancement disclosed on every stone.
What we publish
Buying data and market data, separately
Two different things live here and we keep them apart. Buying data is what a specific item is: origin, weight, grade, treatment, price. Market data is how a category behaves: what drives price, what a grade is worth, what to verify before you pay. Neither is a securities offering, and nothing on this site is an offer of participation in a mining venture.
The standard
What we publish on every item, without being asked
The mineral trade runs on asymmetry. The seller knows what a stone is and the buyer usually does not, and a great deal of the industry’s margin has historically come from that gap rather than from the goods. We publish the gap closed. Every item carries:
- A serial that stays with the item permanently — on the listing, the invoice, any laboratory report and any future resale enquiry.
- Named origin — the specific mine or mining area where we can establish it, not a country and a shrug. Where origin is our assessment rather than a laboratory’s finding, we label it as ours.
- Treatment and enhancement — stated before purchase, at the level and by the substance, never discovered afterwards.
- Measured weight and grade — assessed in daylight, not under a lamp chosen to flatter.
- The price, in full — and what it excludes.
The test we hold ourselves to: nothing a buyer would want to know should be discoverable only after payment. If we cannot substantiate a claim, we do not make it — and where we have only our own eye rather than a laboratory report, we say which.
Process
How buying works
- Tell us what you are actually solving for. A collector, a bench jeweller cutting to a setting, and someone buying a gift are three different problems and the right stone differs. Budget is useful information, not a weakness.
- We show you what exists. Photographs and video in both daylight-balanced and incandescent light, because emeralds shift between them and one flattering image is how stones get oversold.
- Everything is disclosed in writing. Origin, weight, grade, enhancement level and filler type — before any payment.
- Laboratory submission if you want it. Any stone, any laboratory you name, before it ships. We forward the fee unchanged and do not mark it up.
- Payment, then insured shipment. Fully insured, tracked, signature required, shipped from the United States. See shipping and insurance.
Roadmap
Three layers, and where each honestly stands
| Layer | Status | What it covers |
|---|---|---|
| Minerals | Live | Colombian emeralds — rough and specimen, loose cut stones, finished jewelry and trade parcels. Bought in Boyacá, graded here, shipped from the United States. |
| Oil & gas | Education only | We publish how the market works for private buyers — grading, differentials, what gets offered to retail and why most of it is bad. We do not currently sell anything in this layer. |
| Gold | In development | Single-origin refined bullion with documented chain of custody from a named mine. Not open to customers. When it opens it will be a sale of metal, nothing more. |
Where a layer is education rather than commerce, the pages say so. Nothing published on this site is an offer of participation in a mining or drilling venture, a security, or investment advice. We sell physical goods and we publish market information. Those are two different activities and we keep them visibly apart.

Every handbook below is readable in full on this site with nothing asked of you. They exist because an informed buyer is a better customer and a worse mark.
- The Emerald Buyer’s Handbook — grading, treatment, origin, verification
- The Gold Buyer’s Handbook — fineness, refiners, premiums, storage
- The Oil & Gas Handbook — grading, differentials, what private buyers get offered
- Energy & Compute — stranded power and the economics behind it
