The Right Time To Sell

With the price of gold over $1,000 per troy ounce, people have asked me if they should sell Great Aunt Edna’s rings and bracelets.

Is the price of gold going to go up more based on fears of economic troubles? Will governments around the world take actions that change the price a lot, one way or another? And what’s the value we should put on loyalty to Great Aunt Edna’s memory?

A geologist cannot usefully advise you about economic policy made at the international level or about balancing Edna’s memory versus being able to pay the rent. But the high price of gold has led me to some rumination about the world’s first, extraordinarily precious metal.

Not all that glitters is gold, to be sure, but when I once had the chance to personally heft a gold bar (no easy feat for a lightweight), I surely admitted that gold has a strong allure. I was visiting a geologist at Round Mountain, Nevada, where the gold comes out of an open-pit mine and is processed on-site. The final step of the work creates the gold bars, which are called “dore.” That term means they have not yet been highly purified, so they can have some silver and other metals in them. But they’re mostly gold.

It is tough to think clearly about gold when you are in the presence of a lot of it, like it is tough to be completely unemotional in the presence of the Hope Diamond. But here, in the safety of print and away from stacks of gold bars, let me lay out a bit of what I know about gold.

People likely learned to mine gold long ago where it occurred in the richest stream and beach deposits. If gold grade is high enough, you can literally simply look down at your feet as you walk along a sandy beach and pick out small nuggets and grains of gold. When gold grade drops below that, individual prospectors can either pan for gold or send their sandy diggings down sluices to process it. Both approaches help separate dense gold particles from the lighter sand around it.

But gold is found in quite different geologic settings, too. It’s often in veins of quartz in other rocks. (In the ancient world, Mother Nature was thought to be in some sense alive, so it was not surprising the Earth would have “veins,” just as you have veins in your arms. Odd, from a modern perspective, but true, and preserved in our language down through the millennia.)

Geological veins are made by fluids, circulating in the Earth and depositing minerals that get left behind. I spent several years in graduate school studying how much gold will dissolve in fluids in the Earth. (Odd, also, but true, wasting my youth in such a way.)

One impressive thing about gold in your daily life is that it does not dissolve at all. The ring on your finger will not dissolve if you throw it in the boiling pot of pasta water. The gold on your crowned tooth does not dissolve despite years (or for some of us, decades) of being immersed in spit, hot coffee and all the rest.

So the question for my studies as a student, essentially, was what conditions and chemicals in the Earth made it possible for gold to dissolve into fluids and move, then drop out of solution and into the veins from which we can mine it today. The answer had to do with sulfur and oxygen and some difficult points of chemistry, with lots of calculations thrown in to add to the labor. But the main issue was that the conditions where gold dissolves are rare, indeed – just as you know from your day-to-day living.

And that brings us back to Great Aunt Edna’s rings. There is no harm in taking them in and asking for a bid. But before you take the cash and walk away from the family gold, I would recommend leaving the buy-back place and going home. One night’s sleep could help you reach a decision you will not regret, one way or another. There was, after all, only one Great Aunt Edna.
