The diamonds are ours.
We keep our own inventory of loose stones, natural and lab-grown, and we buy them without a middleman in the way. So you get to see them in person — and you're not paying for anybody else's margin.
An hour with a tray of loose diamonds in front of you will teach you more than a month of reading about them. Come and have that hour.
- Brief
Bigger, or cleaner? Let's find out.
Before we open a single parcel, we work out what matters most to you. A budget spent on the largest possible stone and the same budget spent on the cleanest possible stone buy two very different diamonds. Neither answer is wrong — it's just worth knowing which one you'd rather be wearing.
- The case
We start with our own diamonds.
We carry loose diamonds ourselves, natural and lab-grown, in a proper range of shapes and sizes. That means we can usually put stones in front of you the same day you ask — and because we buy them direct, without a middleman taking a cut on the way, you're not paying for anyone else's margin.
- The network
And if it isn't here, we'll find it.
Nobody holds every diamond. When you want something we don't have in the case — an unusual shape, a fancy color, a size we're out of — our network across the trade goes and finds it, on the same terms. We'll always be clear about which stones are ours and which we're bringing in for you.
- Choose
You pick. Then the design closes around it.
Every stone comes with its grading report and a straight opinion from us — what we love about it, and what we don't. Once you've chosen, the setting is finished around your diamond rather than the other way round, which is what stops a lovely stone ending up in a mounting that fights it.
Five things the grading report doesn’t put in large type.
Where the weight is hiding.
Carat is weight, not size. Cutters know buyers shop by the number, so a stone can be left deep to hold onto weight you'll never actually see. Two one-carat diamonds can differ by half a millimeter across the face — and that's visible, on a hand, from across a table.
The grade that isn't in large type.
Color and clarity get printed big; the cut grade and the proportions behind it are what decide whether a diamond is lively or a bit flat. We'll drop a color grade before we drop a cut grade, every time.
Fluorescence, which is neither good nor bad.
About a third of diamonds glow under UV light. On a slightly warm stone it can help, making it read whiter than its grade. On an already-white stone it can go a little hazy in sunlight. So it's either a discount worth taking or one to walk away from, and the only way to know is to look.
Eye-clean beats flawless.
An inclusion you can't see without a loupe isn't a flaw you're wearing — it's a discount you're taking. What matters is where it sits. Tucked under a prong is free money; dead center under the table is not. No clarity letter tells you which, but a tray of stones will.
Which report it is.
Grading isn't standardized across laboratories, and the same stone can come back a grade or two apart depending on who looked at it. We'll always tell you which lab graded a stone and what that's worth, rather than treating every certificate as the same document.
Why our stones price the way they do.
A diamond usually changes hands several times before it reaches a shop window, and every one of those hands takes a margin. We skip that. Our stones are bought direct and held in our own case, so what you pay reflects the diamond rather than the chain it traveled down.
When you want something we don’t have — an unusual shape, a fancy color, a size we’ve just sold — our network across the trade brings it in on the same terms. We’ll always tell you which is which.
Learn the vocabulary on your own time.
None of this asks you to become an expert — that’s rather the point of having one. But knowing roughly what carat, color, clarity and cut mean makes for a much better conversation when you come in, and sharper questions across the counter.
The Diamond Buying Guide covers all four in plain English, with a scale you can hold up against your own hand to see what a carat really looks like. Five minutes, and we didn’t write it to sell you anything.
Both are real. Pick whichever you love.
A lab-grown diamond is crystallized carbon with the same atomic structure, the same hardness and the same refractive index as one pulled out of the ground — and the U.S. Federal Trade Commission classifies it as a diamond. The difference is time, origin and price, not authenticity.
In practice, lab-grown buys you a visibly larger, cleaner stone for the same money; natural buys you something a billion years old. We carry both loose, so you can hold them side by side and decide with your own eyes rather than take our word for it. And if you’d like to see finished pieces first, the lab-grown collection is in stock today.
Answered plainly.
Can I browse your inventory?+
Yes, and we'd much rather you did. We keep our own loose diamonds — natural and lab-grown — so you can come in and see them under real light instead of choosing from photographs. Bring your questions; nobody here is going to rush you.
What does buying direct actually save me?+
Every hand a diamond passes through takes a margin. Because we carry our own stones and buy them ourselves, there's no wholesaler and no drop-shipper adding a layer between you and the stone — so what you pay reflects the diamond rather than the chain it traveled down. It's the single biggest reason our stones price the way they do.
Should I choose lab-grown or natural?+
Both are real diamonds — the same crystallized carbon, the same hardness, the same sparkle — and the U.S. Federal Trade Commission classifies both as diamonds. Lab-grown buys you noticeably more size and clarity for the same money. Natural buys you something a billion years old. We carry both, loose, so you can look at them side by side and decide with your own eyes. We genuinely don't mind which you pick.
What size stone should I be looking at?+
Honestly, it's the wrong question until you've seen the sizes on a real hand — a carat looks quite different on every finger. Come in and try a few, or start with the Diamond Guide, which has a scale you can hold up against your own hand. Five minutes and it'll make a lot more sense.
What if I find the same stone cheaper somewhere else?+
Send it over. If it's genuinely the same stone — same report number, same terms — we'd rather match it than have you feel you overpaid. And if it isn't the same stone, we'll show you exactly where the difference is. Either way you get a straight answer. hello@privosa.com is the quickest route.
Come and look at a few.
Tell us roughly what you're after and roughly what you'd like to spend, and we'll put a tray in front of you — with an honest opinion on every stone in it. No charge, and no obligation to like any of them.
