FAQ

FREQUENTLY ASKED QUESTIONS

General

Is everything made in Singapore?

Yes. Every piece is designed and handcrafted in Singapore, from initial consultation through to final setting.

Is bespoke jewellery expensive?

Every commission is quoted individually, because no two pieces use the same materials, stones, or hours of work — so there's no fixed price list to point to. What that quote covers is the full process: a real consultation to get the design right, a physical prototype you try on before anything is cast, and handcrafting in solid gold from there, not a resized piece pulled from a shelf. You're paying for a piece that gets made once, correctly, for you specifically — not for a markup on a catalogue item. Message us with what you have in mind and we'll walk you through exactly what it would take.

How do I get a quote?

Bespoke Jewellery

How long does a bespoke commission take?

Typically about 2 weeks from confirming your design concept to a physical prototype, then 1–2 months from approving that prototype to your finished piece — simpler pieces move faster, multi-stone or complex settings take longer. Working against a date — a proposal, an anniversary? Rush production is available for an additional fee, subject to availability.

How do I find her ring size without her knowing?

Borrow a ring she wears regularly on any finger (not necessarily her ring finger — most women don't wear one there day-to-day) and bring it to us for a free measurement, or use an at-home method like tracing it with a fine pencil. As a general Singapore reference, we most commonly work with sizes from about US 4.5 to US 6 — and any bespoke ring can be resized afterward regardless.

Should I choose 18K or 24K gold?

18K for anything worn daily — a ring or bracelet. 24K is more pure, but soft enough to dent with a fingernail, which makes it a poor fit for daily knocks against car doors, gym equipment, or keyboards. 24K suits lower-contact pieces like earrings or pendants better.

Can I use my own materials or family heirlooms?

Yes — this is what we call BYOB (Bring Your Own Bling). We reset existing materials like family heirlooms, outdated settings, or loose stones into a completely custom, modern design.

What ring options do men have beyond a plain band?

Considerably more than most people realize — materials like titanium, tungsten, and mixed-metal inlays, finishes from brushed to hammered to two-tone, and personal touches like hidden engravings or fingerprint casts.

Breastmilk Jewellery

What is breastmilk jewellery?

Breastmilk jewellery preserves a small sample of your own breastmilk — around 5 to 10ml — and sets it into a pendant, ring, or bracelet in solid gold or silver. The milk is stabilized so it holds its exact colour and texture permanently, creating an everyday wearable keepsake of your maternity journey.

What's a thoughtful push present?

A push present is a gift given to a mother to mark the birth of her child. Popular choices include eternity rings, birthstone jewellery, and engraved pieces — but breastmilk jewellery is one of the most personal options, since it's made from the mother's own body rather than just symbolizing the moment.

Fur & Ash to Diamond

How does fur to diamond work?

We require 20g of your pet's fur, all of which is used in the process — nothing is wasted. A courier is arranged to collect it directly from your door after checkout, and your diamond is grown over a 2-month turnaround, with surveillance footage of the entire process and an IGI certificate on completion.

See cuts, carats & pricing
Can you make a diamond from ashes instead of fur?

Yes — the same process used for fur to diamond also works with cremated ashes, human or pet. The carbon extraction and growing process is identical; just let us know which material you're working with when you commission.

What do VVS and D colour actually mean?

They're two of the 4Cs used to grade every diamond. D colour is the highest grade on the colour scale — completely colourless. VVS (Very, Very Slightly Included) means any internal inclusions are invisible to the naked eye. Together they represent the highest grade commonly available in the Singapore market.

Classes & Workshops

Do you offer silversmithing classes in Singapore?

Yes — private studio classes for up to 2 people, 3 hours long, where you make your own solid silver ring from scratch. All materials are provided and no experience is needed; you're taught by the same goldsmiths who make our bespoke commissions.

See class pricing & booking
What is lost wax casting?

It's a jewellery-making technique where a design is carved in wax, then invested in plaster and heated until the wax melts away, leaving a cavity that molten metal is cast into. It's one of the core skills taught in our silversmithing classes.

Learn lost wax casting with us
How much do private studio classes cost?

S$120 per person for a 3-hour private session, up to 2 people at a time. That includes all materials — you leave wearing the solid silver ring you made.

Book a private class
Do you run corporate or mobile workshops?

Yes — we bring a mobile silversmithing setup to your organization's venue anywhere in Singapore, so a team event can be a hands-on making session without anyone visiting our studio. Quoted based on group size and format.

Enquire about a corporate workshop
Do you take on apprentices?

Yes — we're actively looking for apprentices and like-minded creatives to grow with the studio, not just pass through a single class. It's part of what we call The Guild: a platform for aspiring jewellers and designers to keep learning past a one-off session.

Enquire about an apprenticeship
What do apprentices learn at House of NDAG?

The full modern making pipeline: 3D CAD design, 3D printing, lost wax casting, and hands-on benchwork — soldering, piercing, shaping, and polishing. Apprentices work alongside our goldsmiths on real client commissions, not simulated exercises.

Can I cast my own jewellery designs with you?

Yes — if you already design your own jewellery, our Designer Casting Service is a platform to bring your creations to life. Send us your 3D CAD file, or work with us to model one, and we'll 3D print and lost-wax cast it in solid silver or gold.

Manufacturing & Bring Your Own Design

Do you use AI to design my jewellery?

No. We don't generate or design jewellery using AI. If you've used an AI tool to create a concept image, that's simply your starting point — from there, every design decision, correction, CAD model, print, cast, and finish is done by hand by our goldsmiths, the same as if you'd brought us a hand-drawn sketch instead.

See how the process works
Can I use an AI-generated design for my jewellery?

Yes — it's an increasingly common starting point. An AI render is great for visualizing an idea, but it doesn't account for how metal actually behaves: wall thickness, prong strength, whether a shape can physically hold its form on a finger. We review every AI-generated design before modelling it, flag anything that needs adjusting for durability, and make sure the finished piece is something you can actually wear every day, not just something that looked right in a render.

Send us your AI render
I only have a sketch — can you help?

Yes. Send us a sketch, a reference photo, or even an AI-generated concept image — we'll model it in CAD, refine it with you, then 3D print and cast it in solid gold or silver. No prior design work needed on your end.

Start from a sketch
I already have a CAD file — do I still need a design consultation?

No. Send us your CAD file and we'll 3D print it in a castable material and cast it in real metal — no design work required on our side.

Send your CAD file
I have a wax model — can you cast it?

Yes — that's the fastest path we offer. Your wax is sprued, invested, burned out, and cast the traditional way — made in Singapore.

Get your wax model cast
Do you offer 3D printing without casting?

Yes — as a standalone service. Choose castable resin if you plan to cast it elsewhere later, or standard resin for a physical prototype or try-on piece that isn't meant to be cast at all.

Enquire about 3D printing only
Are you a jewellery designer or a jewellery manufacturer?

Both. If you already have a design — your own, or one from another designer — we work purely as a manufacturer: 3D printing and lost wax casting it in Singapore, no design consultation attached. If you don't have a design yet, we do that too, as part of our bespoke service.

See the manufacturing-only service
I'm an independent designer or a small jewellery brand — can you manufacture for me?

Yes. We work with independent designers, small brands, and hobbyists directly — there's no minimum order quantity, and each piece is 3D printed and cast individually rather than run through a bulk production line.

Enquire as a designer or brand
What metals can you cast my design in?

18K gold, 24K gold, or sterling silver — the same metals we use across all of our bespoke and manufacture-only work. If you're not sure which fits your design, tell us what you're making and we'll recommend one.
