Midwave UV lights are outstanding! I cannot believe the colors produced by different calcites with it.
Generally speaking, UV lights really open up a whole additional aspect of the hobby which has been off limits in the past due to how expensive the lights have been, but recently, they have really became much more affordable. The midwave light shown here is $100, as an example.

Thank you for watching! I have really been enjoying learning about this whole unseen world of fluorescence. I really cannot wait for spring and to be able to re-visit some of the underground mines around here with my new lights, I just need to figure out a nice way to carry them all in.

Your enthusiasm is highly contagious. What can I say that everyone else hasn't? You really sparked my interest on the mineral composition in general. I recognize the copper greens and iron reds in most of my collection, but there are so many more combinations of minerals that can produce similar effects rooting them out can be a task. I love a good light show and you didn't disappoint today. Woot on the win!

Super cool calcites! Regarding what causes the very rare blue fluorescence in these "Terlingua-type" calcites, there has been a fair amount of scientific research to identify what is causing it with the best answer I've found being "organics". These organics may have become absorbed after formation, meaning that only the crystals very close to the organic subtance would have this blue color where others would have the pink/orange that is common with Mn2+. No telling without further scientific research, but it's what makes rocks, crystals, and gems so cool! BTW, I'm not a geologist, but was a chemist by training.

I've noticed that many calcium minerals are really good under midwave, with calcite being the most common of course. Fluorapatite, agrellite, powellite, and some scheelites are really good under midwave. Fluorapatite in particular really seems to love midwave - I've found that a bunch of my fluorapatites that barely react under shortwave or longwave are actually pretty bright under midwave. I believe the violet/magenta/pink colors in calcite under midwave are from a combination of manganese and cerium activators. Varying percentages of each activator during the crystals' growth determines which end up being violet and which are pink. I have some calcite from Pennsylvania with mixed purple and magenta MW fluorescence in the same vein.

@sstimac 7 месяцев назад

My Fluorapatites are spectacular under MW, for sure. Some look nice under SW, but MW is leagues better.

Thanks for this. Calcite started me on my mineral journey into conscoiusness . I wasnt aware of the different uv lights . That said time to get a mid wave light looking forward to go through my many types of calcite . Ive got some boulders that im carving bowls out of produced lots of others so it will be cool to see what they look like under different light waves. Tried the the most common uv light years ago but never new there were other uv lights . Thanks for passing on the knowledge and links.

As Jared said, the prices will only decrease. I did my best to keep these lights at $100 and not a dollar more. I am working on a design now that should bring the cost down even more. They'll be a smaller form factor, but the price will be phenomenal. I'm not sure when they'll be released yet.

Calcite is an interesting stone as you can get double refraction and is the premise of "stealth camo" or "invisibility cloak". It would have to be crushed down and woven into a textile (think 3M)

That's amazing! I thought that midrange was pretty much just a wasted band of UV. But I was thinking about the 295 range, which is when you are talking about fluorescent minerals! but that's really cool! And you said your lights are in the 300+ range? I'm glad you joined the fluorescent minerals society so that maybe you can get your questions answered and can depart that knowledge on to us! Thanks Jared!

@steveegbert7429 7 месяцев назад

Congrats on the light win! I know those things aren't cheap for good ones. I wonder if the different color in your same road cut calcites might have something to do with a slight difference in crystal structure, causing somewhat of a light splitting prism effect.

@sstimac 7 месяцев назад

I think mine are currently the highest quality at the lowest price. I don't think you'll find better at $100 at this time. In regards to the different colors we see these fluoresce. This is not due to reflections off crystal planes, it's actually varying concentrations of activator elements like manganese, lead, and cerium.

@workoutmusicvideos92 6 месяцев назад

I find the good old-fashioned fluorescent black light works way better than all the LED black lights. It’s not even close. Like you said, the bright ones tend to be way too much

@CurrentlyRockhounding 6 месяцев назад

How many modern filtered LED UV lights have you tried out? What kind or brand of filtered lights do you think are best?

@sstimac 6 месяцев назад

This simply does not hold up to fact. Old fashioned black lights don't produce light in the correct wavelength nor are they filtered. If you're relying on an unfiltered 395-405nm light to view fluorescent minerals, you're hugely missing out.

@pamelaklemp5615 6 месяцев назад

I'm curious about the times of the day... wonder if each rock would emit different color patterns or color intensity during different hours within a 24 period? I've heard that some rocks actually have time-frames when they are more (or less) actively intense. Might that be true? If so, that's a perfect experiment for you to undertake and photograph them. Maybe a good magazine would feature your research findings about it too.

@sstimac 6 месяцев назад

Rocks aren't aware of what time it is. Fluorescent minerals respond to the wavelengths of UV light. Even daylight reactive minerals like some hyalite from Zacatecas or fluorite from England respond to the quality of UV light regardless of what time it is. Although, you could probably argue that the color shifts around dawn and dusk would make the intensity of their daylight fluorescence less than it would be under other conditions.

@pamelaklemp5615 6 месяцев назад

@@sstimac Thanks for your informative reply. Interesting about the possibility of dawn and dusk on them. I had read somewhere something like that regarding the different moon phases affecting some rocks and crystals.

Have you tried combining 2 or 3 different wavelength lights together at the same time? Does that have any different effect?

I have and if you have a rock that produces different colors or has a mineral that shows well under one spectrum and not the other, you can get them both to react under the two lights.

Lol I was about to ask what determines a calcite's fluorescence as you admitted you have no idea. I wonder if the fluorescence would persist when crushed to dust or dissolved in an acid?

@sstimac 6 месяцев назад

The fluorescence remains when calcite is crushed. In fact, there is concrete from Franklin, NJ that's made with fluorescent sand and it's s awesome. It does not retain fluorescence after being dissolved in acid.
