Items that contain the most gold by weight are those that are made from 24-karat gold or are as close to pure gold as possible. However, these items might not be very common due to the softness of pure gold. (Pure gold is 24 karats, but it's very soft and malleable, making it less suitable for jewelry that needs to withstand daily wear.)

Back in 2014, a gang of thieves broke into the Yogi Berra Museum in Little Falls, New Jersey and stole two American League Most Valuable Player plaques and some of the World Series rings that Yogi had been awarded during is long and storied career as a Yankee. At the time, the plaques were estimated to be worth as much as $350,000 each, and the rings were said to be worth more than $40,000 apiece.

Have you visited a jewelry factory recently? Or the business place of a jewelry maker who repairs jewelry?

If you have, you have noticed that they are noisy places. Grinders, polishers and other pieces of machinery are whirring away. And do you know what? The specific places where that noise is coming from are the same places where you are most likely to find small amounts of gold, platinum and silver dusts and powders that can be worth much more than you suspect.

We have all been there when recently engaged young women show off their new “rocks” to friends or work colleagues. “How big is the diamond?” has been the most important question that people want to know (or are too respectful to ask) at those times. Yet a recent article in MarketWatch.com, “J-Lo’s engagement ring is reportedly worth $1 million — is it time to ditch the diamond?” implies that young people today are losing interest in how big a diamond is in an engagement ring, or what it is worth.

“My grandfather was a master jeweler and jewelry repairman,” a caller told us recently. “Unfortunately, he recently passed away, and now we have the job of emptying his workshop. Can you give me some advice on what we should be looking for?”

Not long ago, we had a call from a man who had bought a box of 16 rolls of gold-plated jewelry chain at an auction where the assets of a closed jewelry manufacturer were being sold to the public. “I weighed the box,” he told us, “it weighs about 12 pounds . . . so what is it worth?”

If you are a regular reader of our blog, you know that we like to offer advice on where to find platinum, silver and gold scrap in old factories. So we thought it would be interesting and informative to profile one such building - the old Tiffany manufacturing facility in Newark, New Jersey, that has now been converted to residential apartments. It is located at 90 Tiffany Boulevard - where else could it be?

Abracadabra! 

Back in medieval times, alchemists tried to convert silver and base metals into gold. At the same time, magicians tried to use gold to help their clients ward off evil, attract love, or cure various diseases.

Over the years titanium has been used mostly in aerospace and industrial applications, and with good reason. Titanium is nearly as hard as steel, but it weighs much less. It is extremely resistant to corrosion and wear. It resists deformation -  you are going to have to jump up and down pretty hard on a titanium ring or pipe to get it to flatten.

We recently spent a few hours in the company of an expert jeweler, looking through a batch of old jewelry scrap. It was amazing to watch him work. He seemed to have a kind of sixth sense about what he was looking at. He picked up a small chain and said, “This is solid gold.” Then he looked at an old watch and said, “The case is gold plated, not worth much.” Then he looked at a ring and said that although it looked like platinum, it was base metal that had a thin level of chrome or other bright-metal plating applied to it. Again, not worth more than a few cents.

Do you have a quarter, a silver dollar or another coin that you would like to have made into a ring?

If so, you can quickly find a company that will refashion your coin into a ring, just by searching online. It seems that lots of people are starting businesses that do it.

...Presto! Gold plating has happened. It’s a simple process that has been used for years to apply gold plating to jewelry and other metal items. But today’s post is not about recycling those items. It’s about reclaiming gold from the tanks where the process took place. Let’s take a closer look...

Have you ever failed to realize that an old ring, an old lab vessel, or a bit of white metal scrap was made of platinum? If you have, you are not alone. Because platinum is a white metal, it is easy to mistake it for silver or even something as low-end as polished pewter, stainless steel or even aluminum. Here are three facts that can help you recognize platinum more quickly and reliably.

Since ancient times, jewelers have been creating rings and other pieces of jewelry by pouring molten metal into molds. What methods did they use? Have any new methods have come along? It’s a fascinating subject that you should understand if you invest in precious metals. In today’s post, we’ll take a closer look.

On our blog today, we're featuring a fantastic video that shows all the work that a company called Baron Rings put into designing and manufacturing the championship rings that were awarded to the 2016 Cleveland Cavaliers. It is inspiring to see a company create something so beautiful. The video reminds us of two important considerations about reclaiming precious metals from older commemorative and class rings…

Platinum wire can turn up just about anywhere where platinum was used in manufacturing. Even though it doesn’t look valuable to the casual observer, it could be. So, if you find bright, shiny white wire... 

Did you know you can search for the term “platinum scrap” on eBay and find mixed platinum scrap for sale? I just tried it, and I found a bag of floor sweepings, said to contain platinum, that I could buy for $500. I found plenty of other items that were said to contain platinum too, including hard disk blanks, catalytic converters, bags of mixed jewelry findings and scrap, and old laboratory testing crucibles. So, could I buy those items, send them to Specialty Metals Smelters and Refiners to be recycled, and make a healthy profit? It’s possible. Yet the chances of it happening are probably slim, because…

Let’s say that in your hunting for valuable items made of precious metals, you come across something made of “Argentium.” It could be a bracelet or other piece of jewelry in its original box with paperwork that says it’s made of Argentium. Or maybe a salesman at a jewelry store or estate sale winks at you and says, “This piece is extra valuable because it’s better than sterling... it’s Argentium!” It’s bright and white and shiny like silver... but what is it?

We would like to tell you a story that illustrates the fact that you could make a lot of money, simply by recycling quantities of gold, silver and platinum that could be hiding in plain sight in companies that manufacture or repair jewelry, dental appliances, silverware, or other common products. 

You could try to perform those operations yourself by burning old electronic components or other metal-bearing materials at home or – preferably – in an outdoor setting where poisonous fumes are released into the air. But we cannot state strongly enough that by doing so, you can poison yourself and release noxious gases into the atmosphere.
