General Care for a Blue Chalcedony

Blue Chalcedony ranks an average 6.5 – 7 on the Mohs scale of mineral hardness, which will be softer than a few but not all of the crystals in your collection.

Throwing it in a bag or box with your other stones might end up scraping it.

It might also do some scratching.

If you haven't held your tumbled Blue Chalcedony gem for awhile, it may look a bit dull.

That's because it's sad.

It misses you.

Oh, and because it needs to be cleaned.

How To Clean Your Crystal

Lucky for us, Blue Chalcedony isn't very porous.

So washing it with soap won't be an issue.

Normally you might have to worry about a left over scent.

Taste too.

But you're probably not putting your tumbled Chalcedony in your mouth.

... I hope.

Besides soap, we have another choice.

Apple Cider Vinegar.

Although it can harm some minerals like a Granite, an apple cider vinegar or lemon juice bath will clean your volcanic stone.

Follow the steps below, and your tumbled Blue Chalcedony crystal will look new again.

  • Fill your favorite bowl with warm apple cider vinegar or lemon juice.
  • Soak your crystal in the bath.
  • Using a clean, soft bristle toothbrush, then gently scrub the rock.
  • Rinse the stone under warm water and pat it dry.

Just like soap, vinegar will leave a smell. But a wash under water will fix that.

How to Charge A Blue Chalcedony Stone

Charging your Blue Chalcedony is as simple using a selenite charging plate or letting it bathe in direct moonlight for several hours.

This stone also responds well to being buried in salt for 24 hours.

Or even better, buried within Mother Earth for 24 hours!

Will Blue Chalcedony Fade?

Your Blue Chalcedony is probably a light blue stone with clouds of white. While many love this light color, there is a risk that it fades all together.

Whether or not this stone fades depends on it's legitimacy.

While Blue Chalcedony crystal is real, it is also quite rare.

Many version you find are simply regular Chalcedony that has been dyed blue.

Dyed Chalcedony will fade over time, and with exposure to sunlight.

Check If Your Crystal Is Real

Your real worry should be whether or not your crystal has been dyed.

That's the most common form of manipulation.

If you're buying raw Blue Chalcedony, then you don't need to worry.

Nobody is faking the raw stone.

But what about the tumbled version?

Is it easy to fake tumbled Blue Chalcedony?

It is not easy to fake tumbled Blue Chalcedony. Resin is the material used to fake this crystal, but the resin can cost more than the gem.

The real version of this stone is a bit rare, but not that difficult to find.

But hey, don't take our word for it!

There are two ways to sniff out fake tumbled Blue Chalcedony.

  1. You can spot a fake crystal by using your finger: a genuine crystal will always be cool to the touch.

  2. Look for cracks in the resin used to fake the stone. The cracks will have pooled ink and be darker in color.

Both these tests exploit that resin is the only reliable way to fake tumbled Blue Chalcedony besides dyed Chalcedony.
