After all the talk about cobalt coatings in tanzanite, I inspected and they are fine, BUT it got me to inspect my other SLC pieces. I am very upset. Spinel is NOT supposed to fluoresce under a UV light. I bought some rose spinel back in the day when they still sold it. Sadly, they all fluoresced strongly under short uv wavelength. I did some research and only synthetic spinel fluoresces under shorter wavelength uv lights (blue)or pink sapphires. It was also STRONG. That thing lit up like a Christmas tree! I am angry because it never said "Lab Created" (I still have the paperwork). They advertised it as real. The other option is not any better. Spinel is often confused with PINK SAPPHIRE. All corundums fluoresce, not just Burmese Rubies. So either they lied about it being lab created or they lied about it being a spinel. I'm very disgusted right now.
By the way, you can use a UV light to detect fillers in your gemstones. I suggests people start checking because after my find, SLC hasn't been honest.
Inspected more of my SLC jewelry w/ tools..very sad

If you use a UV light with a short wavelength (blue light) fillers will glow white..Also, your stone will not be uniform in color. I tested on a few Niassa pieces I bought in the past for fun and the fluorescence was uneven but not as bad as I thought it would be. The Burmese ones were sold so when you put them back to back you can see the difference.

Hahaha, Gemaholic! Does that mean you are too young to know Elroy & the Jetsons?
Has anyone shined their light on Ilakaka Pink Sapphires? I haven't seen them in person, but the pix look off to me.

You mean Mahenge pink Spinel? I have earrings with that gem. Then it's possible that it could be synthetic. Years ago, I took a loose Fire Opal to be examined and the gemologist told me that is was a poorly cut stone and it was a Synthetic Opal. I was furious. I called the company back then was known as Liquidation channel. Unfortunately, I could not return it. Back then they had a no return policy. But the loose amethyst and aquamarine are real and are both set in 18kt gold.Gemaholic wrote: ↑4 years agoAfter all the talk about cobalt coatings in tanzanite, I inspected and they are fine, BUT it got me to inspect my other SLC pieces.

Thanks Gemaholic!!! Just learned a ton. How does one tell the difference between a pink sapphire and a pink spinel then ? Also Can youGemaholic wrote: ↑4 years agoIf you use a UV light with a short wavelength (blue light) fillers will glow white..Also, your stone will not be uniform in color.

I thought "Ruh Roh!" was Scooby Doo. I looked it up and found it WAS from The Jetson's! It started with The Jetson's dog, "Astro" and continued with Scooby Doo.
Well! Ya' really do learn something new every day!
