MY wedding ring was 12k white gold and was 5.1 grams. My first foray into refining white gold was done with it since I figured I wouldn't need it any more what with no longer being married. I tried to sell it off once I was separated but was never given anything close to a decent price and so it just sat in a drawer. But when I finally got around to working with it I am proud to say that I managed to recover 2.49gm of Au and 2.47gm Pd. I melted the Au into 2 1gm beads and one gave them to one of my daughters who made a pair of earrings from them. The Pd I still have in powder form and one day I hope to make something from it. Oddly enough as much as I don't miss the ring I don't feel right selling off the metals and it did my heart good to see my daughter use the Au as she did.

The best way to tell is to examine the Ruby under high magnification. A natural Ruby will have imperfections inside. If no imperfections are present then it's 99.99% probability that it's a lab-created stone, or 0.01% chance it's a very high quality natural Ruby. I think the gemologist can use a refractometer to tell the difference

@Jewelrymaker

5 жыл бұрын

A refractometer will only tell you if it is natural OR synthetic corundum (ruby and sapphire are corundum.) The ONLY way to distinguish between a natural or synthetic is like I said in my previous post. Examine the stone under magnification (preferrably a dark field illuminated microscope) and look for curved striations which would indicate a flame fusion grown synthetic, or look for fingerprint like flux inclusions which would indicate a flux grown synthetic. A natural ruby can be flawless, so just because it has no inclusions in the stone doesn't mean it's a synthetic.

@buggsy5

5 жыл бұрын

In the past a ruby has been any sapphire with more intense color than a pink sapphire. Because of this ambiguity, the international organizations now consider all the chromium bearing reddish corundum to be rubies. Most rubies contain rutile crystals - known as silk. Apparently some are heat treated to make the rutile become invisible to the naked eye. But stones with a bit of silk are far more valuable than one that is "flawless".

Another phenomenal video from start to finish... very informative and interesting to watch. I am always learning something new watching your videos. Question, I’ve watched you do these gold refining videos a few different ways. Is there be a difference in the purity of the gold if you just dropped the gold with just SMB as apposed to using copperas or oxalic acid to drop the gold? Which method do you prefer to use to drop the gold (SMB, copperas or oxalic acid) or do you just go with what you have on hand when your refining?

@sreetips

5 жыл бұрын

Eric, three nines gold can be produced all day long with just SMB. For some refinings, such as Gold Filled, where some junk tends to follow the gold, it may be best to use a different precipitant for the second refining. For example, SMB will drop platinum, if present, with the gold. But oxalic acid or copperas won't. But oxalic will drop copper and tin if present, SMB won't. Copperas could contaminate the gold with iron, but SMB won't. Each precipitant will selectively remove contaminants that the others may not remove. But refining straight yellow gold, inquart with silver and two SMB refinings usually gets the gold very clean. Oxalic acid is like a polishing step. It's used when the gold is already quite pure, like in this video. You can see by the color that the gold is already high purity after parting with nitric before the first aqua regia treatment.

whens the next time you'll be doing another gold refining video? (subscribed on this video btw) watching the different amounts of acid react with the gold and the repeated process of refining and expelling all the base metals/other unneeded precious metals from the gold is satisfying to watch.

Question: This might be a noob question...At 23:20 you "called" it and said you have all the base metals dissolved, leaving you with the the final product, gold. At 24:13 you add Sulfuric acid to dissolve led along with the HCL solution to dissolve gold. Should these two steps not be done separately so led could be precipitated out of the solution before adding HCL to dissolve the gold to provide an even purer gold button? I understand this question would make me sound like a complete noob, but for me to understand I need to know. Thank you for all your high-quality videos, it is really informative....never mind, answer is at 31:10

I recently discovered you can test gold to see if it's real and even determine karat using nothing but a graduated cylinder water a scale and a calculator by weighing it and determining its volume through displacement and using its weight and volume to determine that it is gold and approximately what karat using volume and weight and some relatively simple math because we know the density of pure gold and can determine the density of the different karats through extrapolation or find it online somewhere which I really like because I work within a tight budget so any money I can save on testing supplies if they aren't necessary can go towards something I can't get around like buying glassware or reagents or scrap gold even when I can find a deal on it and possibly one day have enough to try out my idea for a gold brass alloy that is low karat but still looks like higher karat gold and still retains the other properties of gold that make it ideal for jewelry

Hi Sreetips, I was wondering if you could incinerate the tap water off, instead of chancing that some was left in and if that would do the same but better rinsing? I was curious as well in alot of videos a ton of folks use hcl first to rid the base metals out, then they always seem to add nitric after they rinse it from the hcl; the thing that seems to happen more often than not is that some hcl is left and makes some form of chloride salts; if after rinsing the hcl would it in your opinion be better to incinerate it red hot then do your nitric acid? I was just curious thinking that would for sure rid it of all hcl that would be left in it by accident or such.

@nostalgiaarcadefuture

the nitric is the troublesome acid that needs to be driven off or used up, the hydrochloric is actually really weak in comparison, and it reacts with silver to form silver chloride which is a thick sticky mess that will "gum up the works". also Hcl cant really dissolve any of the base metals by itself from what i understand, which is why he uses pure nitric and avoids Hcl until he is ready to make aqua regia. i only ever see him rinse with hcl sometimes but the nitric is the real workhorse and the extremely powerful reagent of the bunch... in fact sometimes after rinsing a bunch of time with water, he will add some hcl and instantly start dissolving gold just from the very tiny amount of nitric left after all the water rinses...the only reagent that seems stronger than nitric acid is high percentage hydrogen peroxide, that stuff just shreds anything in its way, lmao!

Hey Mr Sreetips, just a question.... what if instead of inquarting, you dissolved everything in Aqua Regia at the start, then precipitated the gold and god knows what else out with the bisulphite, washed off the chlorine, then treated with nitric acid to dissolve the base metals, leaving the gold behind ????
