About Rareva Jewels
We grow the diamond. Then we make the jewelry.
A fine jewelry house with its own diamond growing facility. Every stone we set, we grew.
15 W 47th Street, 10th Floor, New York. By appointment or walk-in.
OUR STORY
Seven years growing diamonds. Then a jewelry house.
Rareva began in 2019, not as a jewelry brand but as a diamond grower. We built a facility of more than five hundred CVD reactors and spent years learning to grow stones that would pass the same independent grading as anything pulled from the ground: the same carbon, the same crystal, the same fire.
For a long time those diamonds went to other people's jewelry. Watching that happen taught us something: by the time a stone reached a customer it had passed through so many hands that nobody could say where it came from, and everybody had added to the price.
In 2026 we opened Rareva Jewels to close that distance. We grow the diamond, cut it, certify it independently, and set it by hand in our own workshop. One house, from carbon to finished piece. It is the only way we know to stand behind every stone completely.
FROM CARBON TO SETTING
One house, three stages
Grown. Certified. Set.
Most jewelers do the last step. We do all three, under one roof, which is why we can tell you exactly where your diamond came from and exactly who made your ring.
In our own reactors.
Every diamond begins as a seed crystal in one of our CVD chambers and grows, layer by layer, over several weeks. We control the process from the first day, which means we can grow to a specification rather than sort through what a supplier sends.
By someone who isn't us.
Each stone is graded independently by IGI or GIA for cut, colour, clarity and carat, and the report travels with the piece. We grow the diamond; we don't grade our own work.
By hand, to order.
Nothing is made until it's asked for. The setting is finished in solid gold or platinum by a jeweller at a bench, checked against one standard, and sent to you, and only you.
THE SHOWROOM
47th Street, tenth floor, in the Diamond District.
The showroom is where the house lives in person.
New York's Diamond District has been the centre of the trade for a century. Our showroom is on the tenth floor of 15 West 47th Street, where you can see loose stones under a loupe, try settings on, compare cuts, and sit with a designer on a custom piece.
We'd rather you came in than took our word for it.
-
i.
By appointment or walk-in
Appointments give you time and a quiet room. We recommend one for engagement rings or anything bespoke. Walk-ins are welcome whenever the showroom is open.
-
ii.
Virtual appointments
For customers outside New York, we run full appointments by video. You'll see stones on camera, compare cuts side by side, and have a designer walk you through every choice.
-
iii.
Loose stones, on hand
Because we grow our own, we keep certified loose diamonds in the showroom. Choose the stone first and we'll build the ring around it.
GROWER TO WEARER
What it means here
Direct is an overused word. For us it means the reactor is ours.
-
i.
You buy from the people who grew the stone.
Ask where your diamond came from and the answer is a reactor with a number on it. Ask who set it and the answer is a person at a bench. Nobody in between.
-
ii.
Grown to order, not sorted from stock.
Because we control the growing, a two-carat oval in a specific colour isn't something we search for. It's something we make. That is what “made to order” means here.
-
iii.
The relationship doesn't end at checkout.
We resize, clean and re-polish our pieces. We keep your file so the next time you walk in, we already know what you own and what would sit beside it.
