Forge & Facet
Build a piece of fine jewellery yourself — and learn how it’s really made.
Two hands-on tools, free and no sign-up: forge your own gold in the melting pot, then facet your own diamond in the studio. It’s the real bench, made playable.
Chapter One
The Melting Pot — mix your own metal
I’m Daniel. Pour metals into the crucible, hit smelt, and I’ll tell you exactly what alloy you’ve made — the karat, the colour, whether it’s any good, and why. Same thing I do every day, minus the flame.
The interactive crucible needs a modern browser. Here are the classic recipes it’s built on — every one a real alloy we can cast.
Chapter Two
The Diamond Studio — choose your stone
You’ve mixed the metal. Now choose the diamond that goes in it. Pick a shape, move it through different lighting, and watch why the cut matters more than the size — the thing photos never show you.
The diamond studio needs a modern browser — read on for how the 4 Cs and cut quality work.
How mixing metal actually works
Pure gold is beautiful but soft — you could bend a 24-karat ring with your hands. So jewellers blend it with other metals. That blend is an alloy, and the recipe decides everything: how hard it is, what colour it turns, whether your skin will like it, and what it’s worth.
Karat is just how much gold is in the mix
Karat measures gold content out of 24. Pure gold is 24K. Mix three parts gold with one part other metal and you get 18K (75% gold). Half-and-half-ish is 14K (58.5%). Lower karat means less gold, but more of the other metals — which usually means a harder, tougher piece that stands up to daily wear.
The other metals choose the colour
Add copper and gold warms toward rose. Balance copper with silver and it stays classic yellow. Bleach it with palladium or nickel and you get white gold. The gold content — the karat — can be identical; only the recipe changed.
Looks like gold isn’t the same as is gold
Brass (copper + zinc) and Nordic Gold (the alloy in €-coins) look convincingly golden and contain no gold at all. That’s exactly why we test — density, acid, magnet, XRF. Pour some brass in the crucible and watch the melt value stay at zero.
Not every recipe is wearable
Purple gold is real gold — mixed with aluminium into a stunning violet — but it’s so brittle it shatters like glass. Lead is soft and toxic. Part of the craft is knowing which mixes belong on a hand and which belong in a museum case.
Questions I get asked every week
What does “karat” mean in gold?
Karat is the share of pure gold in an alloy, out of 24. 24K is pure gold; 18K is 75% gold; 14K is 58.5% gold. The rest of the mix is other metals added for strength and colour. Karat is about how much gold — not how good the gold is.
Why isn’t pure gold used for rings?
Pure 24K gold is too soft for daily wear — it scratches, bends and loses its shape. Alloying it with copper, silver or palladium makes it hard enough to hold a setting and survive years of wear, which is why 14K and 18K dominate.
What’s the difference between yellow, white and rose gold?
They can all be the same karat — the same amount of gold. The difference is the alloy: copper makes rose, a balance of copper and silver keeps it yellow, and palladium or nickel makes it white. White gold is usually rhodium-plated for extra brightness.
Is white gold made with nickel a problem?
It can be. Nickel is a cheap, effective whitener, but roughly one person in eight has a nickel skin allergy. If that’s you, ask for palladium white gold or platinum — both are naturally white and hypoallergenic.
Can you really tell fake gold by melting it?
You don’t even need to melt it. Real gold has a specific density, doesn’t react to acid, and isn’t magnetic; an XRF scanner reads its exact composition in seconds. Brass and gold-plated pieces give themselves away every time — which is why we test anything before we buy or appraise it.
Why does the cut of a diamond matter so much?
Cut is how well a diamond is shaped and polished to handle light — and it’s the single biggest driver of sparkle. A poorly cut stone lets light leak out the sides and bottom, so it looks dull even at a high colour and clarity. A well-cut stone sends that light back at your eye as brilliance and fire. Move a diamond through different lighting in the studio above and you’ll see it instantly.
What are the 4 Cs of a diamond?
Cut, colour, clarity and carat. Cut is the craftsmanship and matters most for beauty; colour runs from icy white (D) to faintly warm (Z); clarity measures internal inclusions; and carat is the weight. Together they set both how a diamond looks and what it costs.
Can Daniel A Jewellery make a custom piece in the metal I choose?
Yes. Custom design and casting are done on-site in London, Ontario — you pick the metal and karat, and we cast, set and finish it here. Start with the crucible above, then bring your recipe in.
Like what you melted?
Every ring, chain and pendant we make starts exactly like this — raw grain, flame and a steel mould. Pick your metal for real, and I’ll cast and set it on the bench in London, Ontario.
