It is usually red, from pinkish to deep 'pigeon's blood'. **What does ruby mean?** In modern crystal tradition it is linked with passion and vitality; July birthstone. This is tradition and belief, not a health claim. **Can ruby go in water?** A quick wash in lukewarm soapy water is fine for most pieces. Ruby is very hard. **Which star signs is ruby linked with?** Leo, Cancer and Sagittarius, in modern crystal tradition. **Where does ruby come from?** Mainly Myanmar, Mozambique, Thailand and Sri Lanka. **Can Ruby go in the sun?** Yes, ruby is generally fine in sunlight and is not known for fading. Still, avoid a hot window or car in summer, because quick heat changes can stress any crystal. Many people use moonlight instead, which suits every stone. See the [full moon calendar](https://www.starseeduk.co.uk/full-moons) for the next date. **How do you cleanse Ruby?** You can cleanse ruby with a quick rinse under lukewarm water, the smoke of incense or a herb bundle, the sound of a singing bowl or bell, a night under the moon and a few hours on a selenite plate. In crystal tradition cleansing clears what a stone has 'soaked up'; practically, it is a gentle routine and a good moment to dust it. Skip salt water, which can leave marks. **How do you charge Ruby?** The most common way to charge ruby is to leave it out overnight under a full moon, then hold it and set an intention. Tradition also uses a selenite plate, a clear quartz cluster or an hour of gentle morning sun. Charging is a belief-based practice, so choose whatever feels meaningful to you. **Can Ruby go in salt?** Dry salt is fine for ruby, but salt water is best avoided. It is hard enough at 9 on the Mohs scale not to scratch, so you can rest it on a bowl of dry sea salt overnight. Brush off every grain afterwards, because salt left in cracks attracts moisture. **What chakra is Ruby for?** In modern crystal tradition ruby is linked with the root and heart chakras. Its colour (red) is part of the reason, because chakra systems match stones by colour. To work with it, many people place it on the body during a short meditation or keep it nearby while they rest. **What zodiac sign is Ruby good for?** Crystal writers most often link ruby with Leo, Cancer and Sagittarius.

In crystal tradition the pairing works because the stones share a chakra or balance each other's themes, such as calm with energy or grounding with clarity. Keep softer stones in a separate pouch so harder ones don't scratch them. **Can you put Ruby and Garnet together?** Yes, ruby and garnet are a classic pairing in crystal tradition. Ruby is linked with the root and heart chakra and garnet with the root, so together they are used to blend and strengthen one shared theme. Both are hard enough to sit together in one pouch. **Can you put Ruby and Red Jasper together?** Yes, ruby and red jasper are a classic pairing in crystal tradition.

Ruby is linked with the root and heart chakra and carnelian with the sacral, so together they are used to blend two different themes. Both are hard enough to sit together in one pouch. **Where should I put Ruby in my home?** A good spot for ruby is by the front door or in a hallway, where tradition places grounding and protective stones. It is happy on a windowsill, shelf or desk. It copes with a kitchen or bathroom, but dust it now and then. Feng shui and crystal placement are traditions, so trust where it feels right. **Can you wear Ruby every day?** Yes, ruby is hard enough for everyday wear. It measures 9 on the Mohs scale, where quartz is 7 and household dust (which contains quartz) is about 7 too. Take it off for the gym, gardening and cleaning to keep it bright. **Is Ruby safe for crystal water?** Only use the indirect method: don't put ruby straight into drinking water. Stones can carry dust, dyes, glue or resin from polishing, even when the mineral itself is stable. Instead, use a bottle with a sealed crystal chamber, or stand a sealed glass beside the stone. **How can you tell if Ruby is real?** Most rubies are heat-treated, which is accepted; very cheap, flawless, bright rubies are often glass-filled or synthetic, so ask for a disclosure. Buying from a seller who names the stone, its origin and any treatment is the simplest safeguard. We list what each piece is on every product page, and you can ask us before you buy. **What is Ruby made of?** Ruby is a red variety of the mineral corundum, the same mineral as sapphire.

Many beginners start with stones they find beautiful, then add clear quartz, which crystal tradition calls the all-purpose stone.
