Agree, the needle inclusions are pretty common in garnet. Coincidentally that one sold pretty quick. Unfortunately no RI or Lab tests, brought from my source in Asia on my travels just last week. African origin, most likely Madagascar?
Ive managed to take pictures of the rest of the parcel now so Ill give dimensions also -
1.28ct (from initial post) 6mm / 5mm / 5mm
1.2ct 6.5mm / 5mm / 4mm
1.08ct 6.5mm / 5mm / 3mm
Now the greener ones. Ive seen internet vendors advertise these as blue garnet, but to me if its not a proper blue its not blue. Am I right in my assumptions ? Im unsure why many dealers are selling this as blue.
This one is on the "bluer" side
1.06ct 7mm / 5mm / 3mm
1.15ct 6mm / 5mm / 4mm
1.34ct 6mm / 5mm / 5mm
Now for some terrible photos of inclusions, I need a better macro lens. Or just A macro lens would do.

I understand 75Turbo's feeling. Under completely different lightings, everything is more or less color change, and then you come to question the reality of the color change character in a stone. It would be interesting to get a picture of another stone, same basic color but NOT color change, close to one of these garnets, under these 3 lightings, so that we could appreciate how one of of the stones changes color and the other does not, even if the background changes too.
This is a 100% blog standard issue with photographing cc stones. It really isn't suspicious or unusual. Messing around with the white balance to get the background color consistent isn't necessaroly going to reflect reality any better. There is a reason a lot of sellers just use photoshop to simulate the change.

Thank you Stephen, you've pretty much hit the nail on the head. Having taken tens of thousands of pictures of gems in my lifetime, adjusting white balance on the camera never changes the colour of the gem. As you correctly point out only the background gets lighter or darker.
Just for the record these pics were merely cropped and pasted in good old Microsoft Paint : )
Isi, understand what youre saying, Ill try and get some pics up tomorrow

As promised.
Initially I tried a purple garnet next to the blue, wrong choice obviously due to garnets tendency to "colour shift".
But you can see the difference between a supposed colour shift, and a real colour change with the blue garnet.
With the purple garnet there is no real visible colour shift to the eye, so that would rightly be questionable.
Next I tried it with an orange zircon, which I know is inert colour wise -
Results as expected, very obvious colour change with the garnet, and the zircon stayed orange.
