Behind Prong Studio

Built by a Jeweller, for Jewellers.

I'm Eric Kojadelian, the owner of VAHÉ Jewellery. I've spent the past seven years running the business and working directly with the public, but at heart, I'm a manufacturing jeweller with a background in trade work.

I'm hands-on across nearly every stage of production, including CAD design, 3D printing, casting, assembly and diamond setting.

I built Prong Studio to make jewellers' lives easier, particularly when it comes to quoting, organisation and managing jobs. It isn't about automating everything. It's a practical tool built by a jeweller who understands the day-to-day challenges of running a jewellery business.

Everything a custom workshop needs

One workflow, from first enquiry to final collection.

Quote faster

Know your margin before you send anything.

Structured quoting built around how bespoke work is actually priced — metal, stones and labour broken out, with your markups doing the maths.

  • Live metal prices, updated automatically
  • Cast vs hand-fabricated, white-gold premium built in
  • Stone & setting pricing by size, style and care
  • Trade-in credits handled cleanly

More in every plan

Everything else your studio runs on.

Beyond quoting and jobs — the day-to-day tools a working bench needs, in the same place.

Stock & display pieces

Keep your ready-to-sell and display stock with photos, SKUs and pricing — separate from custom jobs, always to hand.

Client safekeeping

Log any client-owned stone or piece you're holding and print a receipt as proof — nothing goes missing, nothing gets confused.

Appointments & calendar

Book consultations, fittings, repairs and pickups — then subscribe to a live feed so every appointment shows in Google, Apple or Outlook.

Repairs & small jobs

Track repairs and quick jobs right alongside custom pieces, so the small work never slips through the cracks.

FAQ

Questions, answered.

What is Prong Studio?
A workshop platform for custom and bespoke jewellers — it handles quoting, online proposals, production tracking, clients, repairs, stock and invoicing, in one place designed around how custom work actually runs.
Who built it?
Eric Kojadelian — a working custom jeweller who runs VAHE Jewellery and trained as a manufacturing jeweller before that. He does the setting, CAD, printing and casting himself, and built Prong Studio for his own studio. It's shaped by real bench work, not software-company guesswork.
How does early access work?
It's live and in daily use now. Request access, tell me about your studio, and I'll get you set up. It's free while we're in early access.
Can my clients pay by card?
Yes — add your own Stripe, PayPal or bank payment link and a "Pay online" button appears on the invoices you send. You use whatever provider you already have; nothing new to sign up for.
Does it work with my accounting software?
You can export your invoices to a CSV any time and import them into MYOB, Xero, or hand them to your bookkeeper. Direct accounting sync is on the roadmap.
Do quotes use live metal prices?
Yes — metal prices update automatically, with cast vs fabricated rates and a white-gold premium built in, so your quote reflects today's cost, not last month's.
Is my data mine?
Always. Export your invoices whenever you want — no lock-in, no exit fee. Each studio's data is isolated and private.
Who is it for?
Independent custom and bespoke jewellers and small studios who quote one-off pieces, send proposals, and want to run the whole job from enquiry to collection in one place.

Early access
