Gemstones and priceless metals are pretty, and pretty beneficial, too. Cobalt, silver, diamonds...almost everywhere you look.

You are watching: How are precious metals similar to gems


It"s basic to take gemstones and priceless steels for granted. They look nice. End of story. But that"s just the half of it.

Take, for instance, diamonds, the hardest material in nature — the stylus on document players is fundamentally a diamond. Did you recognize that?

And what around cobalt — a beautiful, sea blue gem, it"s likewise provided in electric vehicle batteries and also very valuable as a result. But it gets a bad rap,as youngsters are sassist to be required to mine for it in dangerous conditions in the Democratic Republic of the Congo.

Silver, too, has actually many kind of supplies beyond jewelry and also tableware.

So, in a Yuletide spirit of public company, here"s a few exciting facts about gemstones and also precious metals — how they form and some of their many provides.

1.Gemstones and minerals are old… incredibly old

As with the world itself, the fundamental facets that become gemstones are at leastern as old as our solar device — about 4.5 billion years. Just think of asteroids, which are leftover objects from the development of the solar device. Some are very carbon-affluent, and diamonds are fundamentally crystalized carbon. Asteroids have the right to likewise organize platinum, gold, iron, nickel, and also rare Earth minerals.

The oldest mineral on Planet is Zircon, which is approximated to be 4.4 billion years old when it"s discovered in Australia.

2.Gemstones come up favor lava

Precious stones and also minerals tfinish to come from much beneath the Earth"s surchallenge. Some, such as diamonds and also peridot, form in the Earth"s mantle. The mantle is the biggest layer of the world that lies in between the core and the external crust. It"s largely populated by silicates, including the mineral olivine and also garnet. Diamonds crystalize in magma simply below the Earth"s crust. These gems and minerals can be pumelted up closer to the surchallenge by volcanic eruptions, yet they just endure as gems if the magma cools slowly. That"s as soon as it crystalizes and also develops minerals. And they"re mined in the crust.

3.Four zones of stone

Gemstones that come from solidified magma kind by a procedure called igneous. These have the right to include quartz (favor amethyst and citrine), beryl (choose emerald and aquamarine), garnet, moonstone, apatite, tourmaline, topaz and zircon.

Some develop in sedimentary rock as soon as, for circumstances, ocean water deposits sediments. Those encompass opals, jasper, malachite and also zircon.

Then tbelow are stones that develop in metamorphic rock. Igneous and sedimentary rock have the right to come under too much warm and push through the activity of magma or tectonic plates. When this happens their chemisattempt and also crystal structure changes — and also they morph right into gems like jade, turquoise, ruby, and sapphire.

And hydrothermal gemstones develop once bodies of water affluent in minerals cools and also gets pumelted up right into cavities and also cracks in the Earth, developing emeralds.

4.Diamond is the toughest of them all

The Mohs scale of mineral hardness was calculated in 1812 by a Gerguy scientist dubbed Friejiyuushikan.orgealthy Mohs. Diamonds are at the optimal of the heap at number 10 — they are the hardest known mineral in nature. At the other finish of the range at number 1 is talc, a form of "soaprock," and the basis of prevalent talcum or baby powder as it"s great for soaking up liquids and smells. But it"s likewise supplied in ceramics, paints, and also plastics. Diamond is composed of carbon atoms, comparable to graphite, however it"s the structure of those carbon atoms that renders diamonds so difficult and graphite so soft. In truth, diamonds are so tough, they are used in market to cut and drill other rocks.

5.Found by "at an early stage man"

You can say we take gemstones for granted as we tfinish to limit their use to jewelry. And the same is true of a valuable steel favor silver. It was discovered in about 3000BC, and also it"s regularly in jewelry. But it"s additionally offered in mirrors for its reflective properties. Silver salt — an not natural compound of silver nitprice — is provided in digital photography to safeguard versus photo piracy. Silver is additionally supplied in batteries, and also various other electronic things prefer circuit boards. And silver nanopposts can even be wstove into clothing to soptimal sweats and also smells clinging to the material.

6.Science in the Scriptures

There are referrals to gemstones and also precious steels throughout the Old and New Testaments. The Publication of Exodus defines an ornate breastplate in great information. It was worn by Aaron, who, with his brvarious other Moses, led the Israelites out of Egypt. According to the scripture, the breastplate featured rope gold, topaz, ruby, sapphire, beryl, turquoise, agate and amethyst, onyx and jasper, emeralds and more. These are ancient stones. Emeralds, in reality, were first mined in Egypt, wbelow Cleopatra adored the green gem. Later, Job writes about "a mine for silver and also a location where is gold is refined" — so there are great indications of extractivity and processing methods. Right up to the Book of Revelation.

Tbelow are other elements, also — less pretty ones, such as sulhair. One of the fifteen times it"s mentioned is in The Book of Genesis when "The Lord rained dvery own burning sulfur on Sodom and also Gomorrah." It was also recognized to the primitive Greeks, that burnt sulhair as a fumigant.

7.Prehistoric mining

We tfinish to think of mining this particular day as a extremely contemporary, partly automated, mega market. And it is indeed that in some areas. But plainly that"s not exactly how mining began. There is archeological proof of mining even in prehistoric times, going ago to 8000 BC. One of the oldest underground mines is situated in eSwantini (previously Swaziland) and dates ago to 4100 BC. They mined hematite tbelow — a principle component of iron. Hematite is shelp to have healing properties, however it was also provided as a red chalk. Mines dating earlier to 5000 BC have been uncovered in Poland also and also Hungary. The rock has been provided for an approximated 164,000 years.
