Clear quartz meaning: rock crystal and clarity

Clear quartz, also called rock crystal, is the colourless variety of quartz. It’s known as a stone of clarity and is said to amplify the energy of other crystals. In the UK it is an alternative April birthstone. In Astrolith readings it isn’t tied to one sign; it comes up when a reading points to clarity.

What does clear quartz mean?

Clear quartz is known as a stone of clarity. It’s said to amplify the energy of other crystals. We think of it as a reminder to see an intention clearly.

Colourless quartz has a long history of its own. In ancient times rock crystal was used mainly to make crystal balls and bowls.

Is clear quartz linked to a zodiac sign?

In Astrolith readings it isn’t tied to one sign; it comes up when a reading points to clarity. That means it can sit beside any sign’s stones in a design.

It does have a birth month. In the UK, clear quartz, or rock crystal, is the alternative April birthstone to diamond; US lists name diamond alone.

How do you choose clear quartz?

Ours is natural and shows tiny inclusions. Glass is the common look-alike. It tends to have swirl marks and round bubbles, and at 5 to 6 on the hardness scale it’s softer than quartz. A perfectly clear bead full of round bubbles is most likely glass.

We offer clear quartz in four shapes: round, faceted, cube and point.

How do you care for clear quartz?

At 7 on the hardness scale, quartz is hard and durable and takes a brilliant polish, so clear quartz suits a bracelet worn every day. Care is the same as for amethyst and rose quartz: warm soapy water is safe, and steam cleaning is best avoided.
