If you like to go hunting for sterling silver or silver-plated tableware, you already know that the items you find at antique stores and estate sales usually fall into these two categories . . .

We have written on this blog before about retrieving gold scrap from old computers. It is actually pretty easy to do, since you can see the gold, which is mostly found on the little pins that are on the edges of motherboards, printed circuit boards, memory chips - in the little pins that are used to plug those devices into surrounding contact blocks.

For today’s post, we’d like to put on our science fiction glasses and think about what the world could look like in year 2050. We admit that it is unlikely that all the following conditions will have arisen by then, but let’s consider them anyway . . .

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.

Back in his student days, our friend Joe was short of cash one month. So to pay his rent, he sold his high school ring to a jewelry shop on 47th Street in New York.

“I took it in, we struck a deal on price and before he even paid me, the guy behind the counter stuck my ring on a mandrel, grabbed a big hammer, and smashed the gem stone that was mounted in it. I left the store with some cash in my pocket, but I wasn’t feeling too great about the whole experience.”

You can find the answer on the Mohs Scale

Is silver more resistant to scratching and wear than gold is? And how does platinum compare to them both?

What will happen to precious metal prices if a trade war causes a number of countries, including the U.S., to charge heftier tariffs on imported goods?

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.

You know what to look for when you are hunting for platinum and platinum scrap, right? You’re looking for platinum engagement and wedding rings, right? Or you might focus on floor and bench sweepings from factories where platinum jewelry was manufactured.
