Which Crystals Can’t Be In The Sun? Find Out Why!

Which Crystals Can’t Be In The Sun? Find Out Why!

Do you know semi-transparent crystals fade in the sun? That’s just a general explanation. The truth is, the basic chemistry of a crystal leads it to fade under sunlight. That’s why today I have combined a list of 13 crystals that can’t be in the sun and the reasons why it happens. If you’re a curious kitty like me, you will love the list of crystals that don’t fade in the sun that I’ve included too.

What Happens to Crystals that Are Kept in the sun?

Every time you treat a crystal to sunlight, it retains the heat and warmth of the sun. This is applicable for warm crystals. On the contrary, cold crystals when they get warmed in the sun, end up losing their cold counterparts to the warm sunlight.

In fact, most transparent crystals are cold. Don’t keep translucent crystals in the sun too. If you’re still pondering, just bookmark this post and refer to it whenever you’re working with the solar energy for healing crystals. Got it? Ask us your doubts in the comments below.

Do Crystals get Overcharged in the Sun?

Can you boil the water too hot? Heck Ya!

While every matter has a solid boiling point, after which the temperature means the same, crystals are almost the same. The ideal time to charge a crystal in the sun is 6 to 12 hours. However, a few healing crystals are so sensitive, they can’t be outside in the sun for even 30 minutes. So, if you have a healing crystal that can’t be in the sun as our list specifies, it is best to avoid keeping it out for solar infusion.

When a crystal is kept at 900angle to the sun, it focuses the energy of the sun leading to a point of heating. This is why crystals such as pyramids and spheres are the worst to charge in the sun. Don’t ever keep it in the sunlight. Instead, go for moon infusions when you’re working with crystal balls and pyramids or pendulums.

While overcharging of crystals is rare, it’s not as if it can’t happen. I have personally seen my feng shui crystal of rose quartz bursting into a million pieces. Thankfully, a new energy was not the culprit, but the overcharging for 3 years without cleansing was.

Today, I don’t let any crystal, feng shui or otherwise be in the sun or anywhere for more than 7 days. I have a calendar noting the placement and date of placing the crystal in every corner of my house. The same holds true for my crystal grid too.

List of 13 Crystals That Can’t be in the Sun

Which gemstone must not be kept in the sun?

Why not keep certain crystals in the sun?

What happens when you keep a topaz in the sun?

How does a sapphire react under the sun?

Find out answers to all your questions below.

·      Fluorite Fades in the Sun

As fluorite is made of fluorspar or calcium fluoride, it reacts heavily under sunlight. It is advised not to keep the crystal under the sun for more than 15 minutes. Exposing to the sun will also make fluorite extremely hot.

·      Amethyst Shouldn’t Be In Sun

Amethyst is made of Silicon and oxygen, in addition to trace impurities of iron that gives the purple stone its distinct color. When amethyst is exposed to UV light, it leads to fading of the deep purple or violet tones of the crystal.

·      Sunlight Fades Opal

Scientifically, opal is the hydrated amorphous silica with water content up to 21%. When exposed to sunlight, opal loses its color that cannot be retained. On the flipside, it is okay for an opal to get wet.

·      Citrine Cannot be in Sun

The yellow variety of quartz, citrine is made of Silicon and oxygen with a hardness of 7. When a transparent citrine crystal is kept in the sun for longer than 4 hours, it fades to form clear quartz. Don’t keep citrine in the sun.

·      Sunlight on Quartz

Another silicon-oxygen tetrahedral structure is quartz. Do not leave your clear quartz out in the sun for more than 2 hours. It will become brittle and break into pieces! Dark colored quartz easily loses its color within a few minutes of midday sun exposure!

·      Turquoise under the Sun

Composed of Copper, Aluminum, polonium, and water in addition to oxygen, turquoise can react vigorously in water and in sun. Moreover, if the seasonal changes are drastic in your area, turquoise can lose almost all its color in the summers.

·      Sun Fades Aquamarine

Composed of Beryllium, Aluminum, Silica and Oxygen, aquamarine can quickly fade into white if kept in the sun for long hours. Although aquamarine is heated to remove the green color, direct sunlight can fade the beautiful blue shade of the stone.

·      Rose Quartz Fades under Sunlight

As rose quartz is basically quartz originating from Brazil fades the most. So, be sure to trace the origin of your pink quartz before you keep it out in the sun. Also, pink quartz fades, but rose quartz often doesn’t.  It is a photo-sensitive crystal!

·      Celestite Loses Color in the Sun

Made from Strontium Sulfate, Celestite changes from blue to white if you keep it in the sun for long. This is because UV rays break the bonds of celestite and bleach its color.  As celestite is a fragile stone, with the fading of the color the strength of the stone also decreases, leading to easy breakage!

·      Sapphires Must not be in the Sun

A type of mineral corundum, sapphires are composed of Aluminum and Oxygen atoms.  It also contains copper, magnesium, titanium, and iron in traces too. When kept under direct sunlight for long, sapphires will lose its blue, pink and yellow colors quickly.

·      Keep Kunzite Away from Sunlight

Made of Lithium, Aluminum, Silicon oxide, and oxygen, kunzite is a gemstone that quickly becomes white under sunlight. Ultraviolet rays in the sunlight will cause kunzite to fade even if it fades slower than an amethyst or citrine. So, be aware when you’re wearing kunzite to the beach.

·      Sun Exposure Fades Topaz

Although topaz has the most stable of colors when compared to other stones in sunlight, it fades if you keep a topaz in direct sunlight for more than 8 hours. Yellow topaz will become brown and deep yellow topaz will become a maroon shade when kept in the sun.

·      Smoky Quartz Loses Color under the Sun

Just like other quartzes, smoky quartz loses its color to become grey or brown. When kept in a glass case, smoky quartz will not lose color as the glass blocks UV light.

What are the Crystals that do not Fade under Sunlight?

Crystals that do not lose color under the sun are:

  • Morganite
  • Malachite
  • Howlite
  • Lapis Lazuli
  • Jade
  • Labradorite
  • Black Onyx
  • Black Obsidian
  • Sunstone
  • Tourmaline

Before you go …

Fading of colors in a crystal is a natural reaction. Always remember that crystals were underground, away from UV rays before they landed in your hands. It is best to infuse sun energy in your gemstones for not more than 8 hours.

Hence, if your crystal is opaque it is okay to leave it out in the sun; however, transparent stones can’t be in the sun for long. Photo-sensitive crystals are best exposed to the sun for under three minutes. Avoid soaking any stone for more than 12 hours at a maximum. Even if your stone is resistant to sunlight, it can fade over time!

There is one way you can Sun-charge any crystal for as long as you wish, without damage. I have 4 pieces of Rose Quartz, a small Amethyst druzy, and a Clear Quartz carved in the shape of a horse, which are kept constantly in the Sunlight, but they’ve neither faded (not even by one shade) broken, nor died. They’ve all been in this situation for over 11 years without coming to any harm whatsoever. I’ve also recently left a 4cm Fluorite octahedron in the same location for three days straight, and again, it was unharmed. (Though to be scrupulously fair, I do have something of an advantage, in that my crystal pals can tell me directly when enough is enough.)

I sense you’re probably wondering how I’m achieving that. The answer is surprisingly simple:

Double glazing.

Who would’ve thought that this most pedestrian of modern inventions, would be the preserver of crystal integrity, millions of years after the majority of crystals were formed?

The secret of it is this: double glazing blocks out ultraviolet light – which, as Ceida said above, is the culprit of all the damage Sunlight can do to crystals – without blocking the useful energy. We (my husband and I) have a dormer window in our home, which gives us a commanding view to the North, East, and West, not to mention a fabulous sea view which my Aquamarines love to sit and look at; and in the niche it makes is our circular wooden dining table which, at 90cm diameter, is plenty big enough to hold numerous crystals. The dormer window is double glazed, so I can leave them there, from dawn til dusk, without hurting them — and that’s something I’d never do intentionally, because they’re like a combination of my best friends, and the children I won’t have (because my RA is not only hereditary; it’s hereditable, and I’m getting too old). The 4 Rose Quartzes, the Amethyst druzy and the “Crystal Horse” reside permanently on the windowsill, protected by the window itself. The weather here on the North Cornish coast has been rotten since Saturday, and it’s belting down rain right now, but I’ve put the following crystals on that table to soak up what daylight there is:

• Alexandrite
• Aquamarine
• Amazonite
• Amethyst
• Apatite (gem-grade Paraibe)
• Black Tourmaline
• Citrine
• Cubic Zirconia (White)
• Diamond (White)
• Emerald
• Fluorite (Rainbow)
• Heliodor
• Labradorite
• Lapis Lazuli
• Morganite (Rose)
• Peridot
• Petalite (Clear)
• Quartz (Clear)
• Quartz (Rose)
• Sapphire (Black)
• Sapphire (Pink)
• Tanzanite

I know that even the ones which are sensitive to UV, won’t be hurt, because of the double glazing; because it’s Winter and the Sun has less strength; and because the bad weather means less UV around generally. I mean, who ever got a natural tan in the Northern hemisphere Winter, in the pouring rain? 😁

Please do remember that as Ceida says, if the Sun is strong then you and your crystals can both suffer, but Sun-charging them is good for them (especially the Solar gems, which don’t charge well in Moonlight) and safer to do indoors, behind a double glazed window. The crystals will get charged this way, and with a simple prayer, they can also be cleansed at the same time; but I’ve never had a crystal overcharge, break, fade or die by this method. The Solar gems in particular seem to bask in it!

Love and Light.
