A few years ago I stumbled onto something called purple gold and I really wanted to buy a pure purple gold ring. However, I was devastated when I found out that it didn't exist...so I decided to try and make one myself.

I love how the chemistry in this video isnāt complicated, itās just Nile learning that casting metal is complex.

Nile: "there was still one problem though, and that was how ugly it was"

As someone who uses sandpaper a lot, I can almost guarantee that the gold that you lost simply just got stuck in the sandpaper. Soft metal is very good at clogging sandpaper grit and with as much sanding as you claimed to have done, I'm genuinely surprised you didn't lose more than you did lol

The beaker drop had me in shambles until I realized it was just a bamboozle

Imagine being a medieval king and some alchemist walks up to you, pulls out a bunch of bubbling, color changing liquids and transmutes your gold into purple gold jewelry. It would blow your mind.

I love how dedicated Nile is to making these videos like $5700 to $7200 on just one ingredient is crazy

I showed this video to my godfather who owns a large jewelry company and he told me he had tried to make this about 5 years ago and this was some of the finest work he had ever seen

One month on, Singaporean here and I just happened to stopped by Lee Hwa for some jewllery shopping. Asked the staff about purple gold and would you know it, the staff informed that this video was shared all over the company internally. Staff shared that Lee Hwa actually experienced a spike in international sales right after this video dropped, so they have Nile to thank for!

As a retired manufacturer of alluvial gold extraction plants in Australia, I was dumbfounded at your experiment, and ecstatic at your result.
Congratulations, you did extremely well.

What makes this ring particularly cooler than most is how genuine it is. The design and process was obviously based on techniques already used but to source it all yourself and go through the process as you did (imo) is what makes that ring so precious. fallowing your own ideals of what you feel made your product worth casting was a sight. the random mistakes that inspired the design and helped the process. truly one of a kind. thanks for sharing this yo!

Fun fact: in the semi-conductor industry, this alloy is known as āpurple plagueā because itās extremely detrimental to parts. Basically, if gold and aluminum contacts touch at high temp, some purple alloy naturally forms. This alloy is both brittle and a poor conductor, leading to electrical or mechanical failure. It was a big issue for a while, and Al and Au are some of the most common contact materials in chips. So yeah, fun facts for ya.
Edit: Wow, this blew up, haha. Glad to start some cool conversations and learning!

Whats crazy is you've advanced a field. no one makes cast purple gold jewelry because of the complications. You are now one of the best in the world at that specific task and made it look like a college students term project.

Hi NileRed,
Nice video.
I have three, probably important, comments for you :o)
I hope you will like it (at leat it may interest scientific peoples, enginers and chemistry educated peoples, or readers).
1Ā°) About your gold amount disappearing; you are right gold when heated vaporizes and some is lost not only litteraly but effectively into fumes... so you are "totaly sane" and absolutely not crasy; your results show this effect quite obviously (and yes dramaticaly).
Not many knows this but gold is a "noble" metal; and as such molecularly despite its weight and density; it ressembles by many aspects to mercury metal or noble gases; when heated; it sublimates partly thus long before melting point is reached some is lost in the air.
2Ā°) Annealing at 600Ā°C is one thing; but often in industial processed it is made several times in sequential mode; so heating, cooling, reheating, recooling, etc.; I'm quite sure that your pink-lilac colour will improve upon cycling more (not a single time (like what you did), but several times) and also by checking the form of the cyle (speed of heating, time of plateau, speed of cooling).
3Ā°) The bubbling of Ar gas into the melt (or N2 gas - that is cheaper) a bit like what is done in chemistry with fluids to degas them is a good option; just like the ultrasonic (or vibrations like some cements, plaster, plastic for molding)...
but
Did you consider reducing the overal pressure; it also degas things more and faster; some use a depressurization chamber for cements, plaster or plastic molding; of course taking into account the volatility of some ingredients or solvents; here despite aluminium and gold are metals and melting point should remain almost the same; the oxidizibility of aluminium should be reduced in lower pressure; but volatility and loss of gold will be worse under reduced pressure than your 5% loss :o(.
Kind regards

The solid substance made of more gold than aluminum is truly lavender. If light reflects the thing, it is fuchsia. The jewel looks so beautiful! Even more beautiful without holes!

I'm a jewellery maker, and I just watched this whole video utterly fascinated. The chemistry, the complexity of casting metal, and the artistry, all combined into an absolute thriller. When I studied jewellery making, I never got to cast gold for budget reasons, and I only know in theory how gold can be dissolved in aqua regia, and I'm just mindblown right now.

The part with the Aqua Regia is exactly how George de Hevesy hid 2 Nobel Prize medals during WWII. To the soldiers who looked around his lab for valuable things, it just looked like a beaker of orange chemicals. After the war, he precipitated the gold back out and the Nobel Committee recast the medals from that gold.

The fact you just keep going and never gave up, for such a simple yet satisfying outcome, I absolutely love it
