Liquid Filled Tubes In Morganite

[SedaGems]

I just finished cutting a nice Morganite from Zambezia Province, Alto Ligonha District, Mutala pegmatite area in Mozambique. I noticed that the photo of the stone looked like it had an effect similar to treacle seen in Hessonite garnet. I put the stone under the microscope and I found a really interesting array of liquid filled tubes. The effect can't been seen with the naked eye but I think it looks pretty wicked in the picture.

are you sure it's natural? i saw the same type of pattern in Russian lab grown emeralds. They grow morganite with the same pattern

Do you have pictures you can post to illustrate that, energyos?

The picture is not mine, i found it at Russian internet website.

I saw the same many times in my Microsope.

These patterns occure in Thairus (Tairus) synethtic stones manufacturer beryl stones.

As i understoud it's a kind of twinning. To get faster grouth they do something with orientation of seeding plate, and krystal does not grow normaly and this pattern occur.

I will try to ask for better photo in Gemological Institute in Moscow today.

The pattern on the photo of topic starter does not look like chanels at all.

[energyos]

oh i looked more carefully the line on the right may be channels.

Than can be strange becouse there are can not be chanels in synthetic beryl.

I will ask GIA color stones instructor, in Moscow GIA office.

Also ask how to separate this feature from naturally occurring gota de aceite which is very desirable in emeralds.

I contacted GIA instructor in Moscow, she confirmed that triangle pattern look pritty much the same with russian made synthetic beryls. But she can say for sure only if she will have the stone. Unfortunatly she is not aloud to give out photos used in education process

[energyos]

russian synthetic beryl pattern very different from gota de aceit

it looks like triangle with only two sides with missing 3rd side

I found a nice article that also cover Russian hydrothermal emeralds.
