Two other crystals that can really help are Turquoise and Chrysocolla, both of these incidentally also contain copper in their chemical make-up. Both crystals are strengthening, potent and supportive energetically of the whole system. Turquoise is a bit higher in vibration than Chrysocolla. If someone is not feeling too fragile then these crystals can help a great deal in the current climate (if fragile maybe something like Amber may be better, see further on).
It can feel very stressful at the moment as well, and there are some crystals that can help with stress specifically. These aren't grounding on their own, but you could couple them with any of the grounders above and carry them round with you or mediate with them holding both crystals at the same time (or hold the higher vibrational one and put the grounder by your feet). Blue Lace Agate is the classic de-stressing crystal of the mineral kingdom, and can bring a deep feeling of peace. Moonstone is a beautiful crystal with a gentle flowing energy that can also help release tension and calm things down. Sodalite is an excellent crystal to help with mental stress - so if you find your mind is going round in circles and won't shut down because of worries and fears it is definitely worth working with this crystal!
An 'all rounder' that can also help at the moment is Amber, which is technically not a crystal at all, but is the fossilised resin of ancient submerged coniferous trees. Amber can always help if everything else is too much, so if anyone if feeling incredibly fragile, or just needs a great deal of soothing, then Amber can really help 'take the edge off' and make everything okay. It is also gently grounding. Amber has been used traditionally to help babies who are teething, which can give you an insight into how gentle it is, but also how effective. Its perfect for the very young, very old, or anyone who is feeling incredibly fragile (which many of us can be with the current situation!) possibly because its not actually a crystal at all and so is much softer and gentler.
One other thing to say, is that its probably wise to work more on your protection at the moment and to strengthen your energy field regularly, as there is so much fear and worry out there collectively, which if you are sensitive and too open you can easily pick up on and think its your own! Some symptoms of not having a strong energy field, as well as feeling very fearful, can be feeling irritated or drained, having nightmares and bad dreams, being easily influenced by others, having a lot of negative thoughts, or feeling threatened. Incidentally, if we are going through a lot of change, we also need extra protection, and humanity at the moment is collectively going through a great deal of change, so it makes sense that we all need extra protection right now.
Some things you can do strengthen your energy field without crystal are actually common sense - so eating a balanced and healthy diet, making sure you get plenty of rest, and having physical exercise and breathing freely outdoors. Being grounded helps with protection. You can also visualise your energy field as an egg shape around you (that also goes under the earth at your feet) and surround this in a protective colour such as turquoise, a deep midnight blue, or violet. For extra protection you could imagine coating the outside in something reflective like silver or gold.
As with all crystals, the best way to decide what may help you the most, is use your intuition, and see what jumps out at you, so if reading this article one or more of the crystals have just 'jumped' out at you, thats your intuition telling you what you may need at the moment! Please remember to keep your crystals clean whilst using them, and tune each one for your highest good and for healing.
