Huge specimen with rich colored velvety blue Hughes. I used white studio lighting to try to capture it’s beautiful as well as natural lighting. This specimen is gorgeous and rich in color and what makes it even more rare is the size! When looking up comparable the last plumbogummite that sold was a fraction of the size!

This would be great for any crystal, rock, or specimen collector or geologist, or ethicist would could truly appreciate its size and natural wondrous beauty! It belongs on display perfect in a collector’s cabinet, or on display at a crystal shop! This specimens had properties that are comparable to the powerful energy of moldavite.

Specimen isn’t perfect but nature rarely is. I tried to include as much information as I can find as well as accurate photographs without any color enhancements/ edits, however the pictures do not do this beauty justice!

As a disclaimer specimen is as-is although I see nothing visible wrong about this natural wonder.

This is from a smoke free home and will be packaged in bubble wrap and shipped using USPS. Feel free to message me with any questions.

Plumbogummite History:

Plumbogummite is an extremely rare lead phosphate mineral that forms in trigonal crystal structures. Its blue-green color is gained from inclusions of Aluminum. This mineral was first discovered in 1819 by François Pierre Nicolas Gillet de Laumont after the Latin words “plumbum” meaning lead and “gummi” meaning gum. This peculiar naming is due to its similarity to a coating of sticky gum on top of a crystal. Plumbogummite is a pseudomorph mineral, meaning that it grows and replaces the spot of another mineral. This crystal commonly grows alongside Pyromorphite but has also been found in association with Mimetite, Wulfenite, Cerussite, Angelesite, and Dufitite. It is found in a few localities throughout the world, most notably France, China, Australia, Germany, Austria, and the United Kingdom.* Although this crystal is often found in a blue-green color, is has also appeared in a pale yellow color in Bolivia.

Plumbogummite Metaphysical Properties:

Plumbogummite metaphysical properties are the qualities associated with our personality that get enhanced due to wearing of this gemstone. Owing to all such metaphysical properties as well as Plumbogummite Astrology, Plumbogummite gem has also grown popular as a lucky gem among celebrities and sportsmen. Commonly, gemstones are used to enhance joy, reduce stress level, boost concentration power and to attain peace of mind.

Plumbogummite Healing Properties:

Since ancient times, there are cultural beliefs that Plumbogummite crystals are believed to heal afflictions in human beings. Beyond their everyday use of beautification in ornaments and decoration,  a dedicated therapy involves using crystals for healing chronic ailments. This practice which utilizes Plumbogummite healing properties is known as crystal healing. Certain crystals are believed to be associated with prominent planets and channelize the energies from these planets into wearer’s body.

Meaning & Energy:

At first look, Plumbogummite may seem like a mineral not from this earth. This foreign-looking stone has immense energies that rival powerful crystals such as Moldavite, Cavansite, and Grandidierite. As mentioned above, Plumbogummite grows in replacement of Pyromorphite; consider how strong this mineral would have to be to overcome this strong stone. Plumbogummite cools Pyromorphite’s fiery center with blue rays of communicative light. We may often find ourselves in an internal mental struggle that pulls us into a dark place. When we are in this despair, it may seem like there is no possible way that we can pull ourselves out. Using Plumbogummite as a tool can allow us to open our throat chakra and use this communication channel to grow.

Crystal Pairing:

Plumbogummite and it’s pseudomorph stone are often strong and for that we recommend pairing it with grounding and amplification stones. This should often be your centerpiece within a crystal grid and can be surrounded by Quartz points as an enhancer. If you are new to crystals and you’re looking to mediate with this piece, grounding stones such as Red Jasper, Black Tourmaline, and Shungite can help.
