Why Nveloop is different
We are not a software company that discovered gemstones
Generic inventory software treats a 4.82 ct unheated Ceylon sapphire the same way it treats a box of screws. It has one field for weight, no idea what a memo is, and no concept of a stone losing 60 % of its weight on the cutting wheel.
Nveloop was written from the inside of the trade. Every screen assumes you deal in parcels and single stones, in carats and pieces, in cash and credit, across several currencies and several countries — and that the same stone will be recut, certified, put on memo, returned and finally sold months later, with every cost still attached to it.

The problem we solve
The stone moves. The information should move with it.
In most gem businesses the record of a stone is scattered the moment it arrives: a weight in a notebook, a payment in the accounting software, a cutting instruction on WhatsApp, a certificate in a drawer, a memo in someone's memory.
“Do we still have that stone?”
Nobody is certain, so someone walks to the safe. Meanwhile the buyer moves on to another dealer who answered in ten seconds.
“What did this parcel really cost?”
Purchase price is easy. Cutting, polishing, lab fees, brokerage, freight and the weight you lost on the wheel are the ones that decide your margin.
“Where is the memo we sent in March?”
Stones on consignment are the most valuable and least tracked part of most gem businesses. They should never be a memory test.
The Nveloop platform
Four systems, one industry
Start with the one that solves today's problem. They share the same data model, so they grow together.
One-time licence
Gem ERP & Custom Software
When your operation is too specific for a subscription product: a system shaped around your own workflow, on your own server or ours.
For laboratories
Gem Lab Management System
Order intake to printed certificate, with online and QR verification so your reports can be checked by any buyer, anywhere.
Sell worldwide
Gem & Jewelry E-commerce
A storefront built for selling certified stones and jewelry online, connected to the same stock you already manage in Nveloop.
Inventory that thinks in carats
Find any stone in seconds — by variety, colour, treatment or weight
A buyer asks for an unheated Ceylon blue sapphire, cushion, between four and six carats, with a GRS report. In a stock book that is twenty minutes of flipping pages. In Nveloop it is one search, and the answer includes where the stone physically is, what it cost you, and whether it is already out on memo.
- Single stones and parcels, priced per carat or per piece
- Full attribute set: variety, colour, shape, cut, dimensions, origin, treatment, certificate
- Up to three photographs and a video per stone
- Multiple locations, with transfers logged between them
- Barcode and QR labels printed straight from the software
- Physical stock counts that reconcile against the ledger
Memo, brokers and the real trade
Consignment handled properly, not forced into a sales screen
Half the colored stone trade happens on memo. Stones go out with a broker, sit with a client for weeks, come back partly sold and partly returned — and generic software has no honest way to record any of it.
- Issue stones to consignees and brokers, then invoice only what sells
- Partial returns and partial invoicing from the same memo
- Broker commission calculated and tracked to settlement
- Partnership and joint purchases split between owners
- Live view of what is out, with whom, and for how long
Every stage of the stone
From rough parcel to certified stone to export invoice
Nveloop follows the physical journey your stones already take, and keeps the money attached to each step.
Purchasing
Record parcels or single stones, split them, and update supplier accounts and payments in the same action.
Cutting & polishing
Issue to a lapidary, track rough-to-polished weight loss, and carry the cutting cost onto the finished stone.
Laboratory
Send stones for testing, hold the report number and treatment result against the stone forever.
Inventory & pricing
Photograph, tag, label and price by carat or by piece, across as many locations as you run.
Memo & sales
Consign, invoice, part-return, chase receivables, and pay broker commission when it settles.
Export & e-commerce
Invoice in the buyer's currency, produce shipping paperwork, and push the same stock to your website.

Currency, payment terms, commissions, shipping fees and export paperwork are part of the system, not something you patch in afterwards.

Customer stories
People in the trade, using it daily
Laboratories, traders and exporters who moved off paper, ledgers and spreadsheets.
Before Nveloop our certificate numbers lived in three notebooks and one spreadsheet. Now a buyer in Dubai scans the QR code and the report comes up in a second. That alone changed how people treat our reports.
The part that convinced me was the memo screen. Every other system wanted me to pretend a consignment was a sale. Nveloop already knew what memo meant.
We were quoting in four currencies and losing track of what a parcel had actually cost us after cutting and lab fees. That number is now on the screen.

Questions
Questions gem businesses ask us first
If yours is not here, ask — we answer as gemstone people, not as a support script.
Is Nveloop only for colored gemstones, or does it handle diamonds too?
Both. The inventory model carries colored stone attributes — variety, colour, treatment, origin, certificate, shape and cut — and diamond attributes such as the 4Cs, so a business trading Ceylon sapphires alongside melee diamonds keeps everything in one stock ledger. Gem laboratories testing both colored stones and diamonds use the same report templates.
We already use Excel and an accounting package. Why change?
Spreadsheets are excellent at arithmetic and terrible at history. They cannot tell you that this exact stone was bought in a mixed parcel, recut twice, sent to a lab, put on memo with a broker in Bangkok, returned, and finally sold in a foreign currency — or what it truly cost you by the end of that. Nveloop keeps one continuous record per stone and hands the finished figures to your accountant, rather than replacing them.
Can I use it while I am travelling to gem shows?
Yes. Nveloop is browser-based and works on a phone or tablet, so you can check whether a stone is still available, raise a memo, or send an invoice from a table in Bangkok or Tucson. Your office sees the same data at the same moment.
How long does it take to get running?
Most Gem Merchant System accounts are live within 24 hours of subscribing, including your item categories and user accounts. Training runs about two hours per user over Zoom, and there is no limit to how many sessions you book. A custom Gem ERP build depends on scope; the discovery call gives you a realistic timeline before you commit.
What happens to my existing stock list?
We import it. Send us whatever you have — a spreadsheet, a CSV export from your old system, even a scanned stock book — and we map it onto Nveloop's fields before you go live, so you start with your real inventory rather than an empty database.
Where is my data stored, and who can see it?
Cloud accounts run on encrypted hosting with per-user access levels, so a salesperson can raise an invoice without seeing your purchase costs. If you would rather keep everything inside your own building, the Gem ERP licence can be installed on a server you own.
