How to Identify Black Onyx?

With the increasing demand for gemstones, there is an increase in the number of fraud cases in the gemstone market, both online and in-store shops. Many sellers are selling other black stones as a deception of Black Onyx. As we know, the foremost purpose of wearing any gemstone is its metaphysical healing effects on our mind, body, and soul. So, one needs to be very careful in recognizing the real Black Onyx.

Here is a little guide on how to identify it:

You can identify a Black Onyx by its natural pattern: base color with straight, parallel, white bands. While other agates have wavy patterns on them.

Many other agates are being sold as Black Onyx these days, and they are dyed black for this purpose. And as well as many other black stones made of softer material.

Its black shade is slightly lighter as compared to other stones like Obsidian, so if you are familiar with the physical properties, you may identify this difference in shades.

Black Onyx has a highly polished and shiny surface. It is reflective and slightly transparent. Make sure that the gemstone does not have any cracks or scratches on its surface. The setting should be clean and well-made.

When it comes to the shine of the gemstone’s surface, the sellers may deceive you by using fancy and low lights in their store to fool the customers. Dark light setups make it impossible for you to see scratches or any other possible flaws in the gemstones.

If you have bought Black Onyx online, and you think that you are still not able to identify a real gemstone from a fake one, you can go to a gemstone expert or jewelry maker, and ask him for an authentic verification of the quality.

How to Cleanse and Charge Black Onyx?

During the journey from handling to trading, shipment, and packing, it may absorb other energies from its surroundings. It may have been in use of any other person. Owing to a number of healing properties, gemstone needs to be cleansed and charged once you buy it. Though these two terms are used interchangeably, they have different meanings. Cleansing a stone means removing all the energies it has absorbed from the surroundings while charging a stone means replenishing its depleted energy due to frequent use in daily life.

One of the easiest and fastest ways of cleansing a Black Onyx is by smudging a sage. A stick of sage is lightened and blown a little, so it releases a slow stream of smoke. Now, place your crystal in the stream of smoke by holding it in your hand and letting the smoke rise on all its sides.

Do this for five minutes and your Onyx will be cleansed. This is the safest method because there is no risk of damage or discoloring of your gemstone. You may feel the smell of smoke from the stone for some time, so try not to do this procedure just before going somewhere. You can also cleanse your Black Onyx by passing it through a candle flame while making sure that you and your gemstone do not get harmed.

You can also cleanse your Black Onyx in seawater. If you do not have seawater, add 3 tablespoons of salt in half a gallon of water. You have to be very patient while cleansing your gemstone via this method because it requires soaking for 12 hours.

If it is raining outside, you can take the benefit of this natural water and let your gemstone take a bath in rainwater for almost 12 hours. Rainwater will remove negativity from the gemstone.

You can also bury your Black Onyx in soil, as Mother Earth helps cleanse gemstones and rejuvenate them. You can also wash your gemstone in river water for some time if you can find a safer way to keep it there.

You can also cleanse your Black Onyx by leaving it in the sunlight for 6 to 12 hours. It not only cleanses your stone by removing the negative powers from the gemstone but also recharges it. Similarly, full moonlight can also cleanse and recharge your gemstone, and it requires more duration than the sunlight does.

Wearing the gemstones with the right intention is as important as their cleansing and charging. You can wear your gemstone in different ways to get different benefits.

While traveling you can carry it with you to protect yourself from attacks and evil spirits.
