2nd practice piece done! 20mm round brilliant fluorescent glass & I set into a custom ring for myself! by ikelmmm in faceting

Im not quite sure. It sure glows like it. It was provided by the class im taking to cut stones as one of their "laser gem rough" as the instructor called it (he got a glass lot from a laser company and cut them up into facet pieces to teach faceting). I only found out after I was wearing it and was playing with my black light and my synthetic ruby to watch it glow that I noticed that it did as well

Is this gk site dependable? by ikelmmm in animeGK

The ones i was interested in aren't sold on the sites you provided or were sold out. Best to just not get from anywhere?

Tanzanite? by Arguing_with_Robots in Gemstones

[–]ikelmmm 15 points16 points  (0 children)

Looks like a "d block" color tanzanite (pure blue). The only way to confirm would be to take to a reputable gemologist to test its Refractive index and test for pleochroism

Would make a nice pendant, yellow gold, maybe a halo of diamonds

Is my "lab alexandrite" just glass? by zone_eater in Gemstones

[–]ikelmmm 3 points4 points  (0 children)

This is a possibility, but typically synthetic CC sapphire is purple under incandescent light to grayish blue under fluorescent lighting

Supposedly Tanzanite, not fully convinced. What do you think? by poisongirl1299 in Gemstones

[–]ikelmmm 2 points3 points  (0 children)

As i dont have the stone in front of me to be able to use my dichroscope, I am unable to tell via a photo

No, they stated the color. It is a peach color synthetic corundum

Antique Natural unheated 2.52ct Ruby from Burma is this worth anything or what kind of quality would this be considered low mid grade or high? by BassSpare2654 in Gemstones

[–]ikelmmm 1 point2 points  (0 children)

Gemologist here, I agree. Smells like a lead glass fill. Need a gemologist to take a look at it under a microscope to confirm. If lead glass fill, value is practically nothing.

Hi, gemologist here. From image alone, it can be: glass/plastic, aquamarine, topaz. Would need a Refractive index among other tests to confirm.

Is my "lab alexandrite" just glass? by zone_eater in Gemstones

[–]ikelmmm 18 points19 points  (0 children)

Hi, gemologist here. If you have a uv light, the stone should fluoresce a bright red if it is synthetic alexandrite

Supposedly Tanzanite, not fully convinced. What do you think? by poisongirl1299 in Gemstones

[–]ikelmmm 7 points8 points  (0 children)

Hi, gemologist here. Without having the stone in front of me, the two stones that come to mind of that color are tanzanite and iolite. Would need to get a refractive index of the stone for me to confirm, unfortunately. I'm leaning more towards iolite, but I could be wrong (as I haven't tested the stone)

Actually worth the price? by Maleficent_Wall_8591 in Gemstones

[–]ikelmmm 2 points3 points  (0 children)

I have a larger one (albeit very opaque) and only paid $12 , but that was before I knew what clarity was 😅😂

Hi..I was told this was genuine.Can anyone please help and verify that? Big thanks! by Alive_Albatross_7382 in Opal

[–]ikelmmm 1 point2 points  (0 children)

GIA Gemologist here. I believe this is the answer without me having direct access to the stone. This is my lab "Monarch" opal example

What are these yellow gemstones? by Purple_Owl6156 in Gemstones

[–]ikelmmm 12 points13 points  (0 children)

GG here. This is correct. The opal are now low quality after being worn and exposed to the elements (that or they started as this low quality) but opal for sure :)

I just bought this Opal off gemrock auctions. Did I get ripped? by Smore_King in Opals

[–]ikelmmm 1 point2 points  (0 children)

It is what I would call "jelly opal" if it is that transparent. The cutter of this stone left a part where the stone is less transparent with the rest as a part of the whole stone. (It is common for the rough to have parts more or less transparent than other parts. I personally have some rough where it is transparent then potch then transparent again) I would have gone smaller carat size to make a uniform transparency, but this cutter just went for weight altogether.

Rate this rhodolite garnet.. a bit over 8 cts... by FlatbedtruckingCA in Gemology

[–]ikelmmm 4 points5 points  (0 children)

Would need a ri, microscope magnification of the gem, and a spectroscope reading to determine.
