I was browsing the Gemological Institute of America’s blog when I came upon a post about fluorescent diamonds. My first gem I had that glows under UV light is Hyalite which gets its glow from trace amounts of uranium. Many minerals glow different colors in UV light, but I didn’t know that diamonds did. Now I do and GIA breaks down some myths around these glowing diamonds.
One myth is that they only glow blue, but the can fluresce in a myraid of colors. Orange, yellow, red, white and green. Atomac structure is key to this phenomenon yet blue is the most common color of diamond fluorescence
GIA is known for its 4Cs in diamond grading. They stand for color, clarity, cut and carat weight. Diamond fluorescence isn’t given a grade like the 4C’s however there are intensity gradings. None, faint, medium, storng and very strong.
Seeing that about fluorescent diamonds got me curios about some of the diamond jewelry I still have in my online store. I put it to the test with my UV black light, but as you can see, it doesn’t fluoresce. .
I got inspired by the blog post to try it on one of my jewelry pieces that is currently for sale in my online store. The piece is a Moldavite (bottom) and raw white diamond (top) that I wrapped in Sterling Silver that is starting to tarnish.
I have the UV blacklight that was given to me by a dealer back in May and I use it to on the hyalite. I used it as you can see in the video to the left, on the pendant and it did not fluoresce.
However, the diamond did reflect the light from the black light as you can see in the video. Its pretty cool that a raw, uncut, unpolished diamond did that.
GIA points out also that fluorescense in gems do not add or take away the value. If the Diamond were to have glowed green I think it would have been fun! It would match the hyalite.

I have always wanted to include an Enhydro in my crystal, gem and mineral collection. Naturally, my first one is so unique that as a writer for CleanTechnica, it's kind of serendipity. CleanTechnica is the number one news site that covers clean energy and cleantech. I...
I remember sitting with Daryl in his shop one day while he was wrapping something in 14K gold-filled wire for someone. I'd just started learning how to wire wrap and was not anywhere close to the level I am at now. In fact, I was very self-conscious about my...
Hyalite opal is an unusual gem that is beautiful in its own way. Many contain trace amounts of uranium which enable the gem to glow under a UV light. I have a small piece in my own collection that I scored at a gem show in Atlanta back in 2019. Recently, I had a...
Black spinel is one of many types of spinel, but it has its own unique beauty and elegance. I have been able to get my hands on two beautifully cut gemstones and am debating on keeping one for myself. These gems (in my tweet below) are cut and faceted with the rose...

I have been wanting to review Maye Musk’s book, A Woman Makes A Plan for some time now. I actually planned to buy it but it came to me as a gift. This sat as a draft in my blog for a good minute. I think a part of the reason why was that I hope that I can write a...
As an artist, I love exploring different metals with my wirework. I’ve wrapped with both brass and bronze before and love how they look before and after they naturally oxidize. Many people have allergies or their skin turns green when wearing brass, bronze, or copper...

Hi, I’m Johnna
I’m an artist from Shreveport, LA who learned the art of wire wrapping gems and minerals into jewelry from Grammy winning musician, Daryl Thompson, who became like a father to me.
He is the one who intrudoced me to the healing world of crystals and I have been learning every since.
This world is ancient but can be applied to modern day times.
My life is hectic–I work from home, am mothering a kitten who almost died, and am living the life of my dreams.
However, we always have to stay grounded and what keeps me grounded is working with the healing gifts of the mineral kingdom to create something.
Every single one of my jewelry designs has a person that is meant just for it.
