This is the scratch analysis:
Rock was able to scratch quartz however was a little challenging because it doesn’t have sharp edges so I had to put some pressure on it but I could say, cutting was not that difficult.
When I tried to cut the rock back and even quartz edges were very sharp, they’ve gotten broken. I could say there was maybe almost no damage or very minimal to the rock.
Regarding the specific gravity, this is what I did:
Weighted the rock = 410 grs
Put on scale container with water = 1300 grs
Rock weight under the water = 1460 (160 grs)
Gravity 410 / 160 = 2.5625
Is this correct?
I believe this rock is not Fluorescent see picture.
But there is something that caught my attention, i think I saw just in one spot some light brown dots inside.

rock weight under water=1460(160grs)
this is correct if you mean rock weight (suspended by a string) under water.
this test wont help much since chrysoprase and beryl have similar density.I don't think chrysoprase would be able to scratch a quartz crystal so I will have to agree with beryl. unless it didn't scratch it but only left a mark that wipes off.

Also, to make sure that what you obtained is indeed a scrath (rather than a streak): scratch the obtained scratch with your fingernail, a scratch should 'catch' your nail a bit (while a streak, which is just a thin line of powder on the glass, shouldn't).

Regarding the scratching point, I did and was like cutting butter, even this rock does not have sharp edges, every single part of the blue material was able to scratch the mirror with minimum effort and just to be completely sure, I used a piece of glass slag and funny man, I couldn’t make a significant mark on the mirror.
Second, at this moment I am cleaning the rock based on Harold’s recommendations and as soon as I remove all the extra material, I’ll run another SG Test. I’ll keep you on the loop of course.
Third, Positive no bubbles and trust me it is not glass slag, I do have a nice piece by the way and structures are very different, I’d say that waxy luster and meaty content of the blue rock are the most important differences but I’m with you, not sure what inclusions are. As soon as I get the rock cleaned, I’ll perform another review.
Last but not least, does anybody know if blue Beryl and aquamarine are the same thing? If not what are the differences?
Thanks in advance.

Even I had done the scratch test in a quartz, I tried in a better piece and man, was very difficult and I scratch was not that that deep.

For questions like “Based on your experience this could be ....”
“Have you got something similar”
“Luster make it look like Aqua, right”
“Between you and me, what is it”
The response was, “I can not comment until we get the results” “Could be made of multiple materials”
In my desperation I asked “does it worth spend money on it” she said “up to you”
Not sure what was my face and then she smiled and said, “Listen, even for decoration a certificate increases value across collectors , you’ll be ok”
By the way Certificate looks very fancy.
So my friends, stay tune, results will take one week, I’ll let you know what is it.
