Hello!!!

I have another "find!" A beautiful watermelon tourmaline bottle that was hidden under dirt and grime. And yes, first thing I did was a specific gravity test - I took it about four times to be sure I was doing it correctly and each time got the same reading. It's specific gravity is 3.18. But with this one, I immediately knew what it was.

However, it has some condition issues. There is major chipping around the neck, and the base, and overall it could use a good polish to really bring out the inner beauty of the bottle.

So my question is, is this done? How would that affect the value of my bottle? Could anyone point me in the direction of a specialist in this area?

thanks!

Dear Cathy,

    Could you please send the clearest photos you have of this bottle to: antiquehouse@yahoo.com?
I will ask Y.F.Yang what he thinks and if he can get it polished.
Best,
Joey

Sadly, from what I can see, this would not be worth spending the money on to polish.. Although the tourmaline is pretty here, it is low grade. The chips at the neck and base are to bad to grind down without loosing correct neck edge, and foot rim.

Some carvers intentionally hollow out a bottle like this much less so as to show off the mineral. But that straight hole down the bottle sort of makes this something to put on the shelf.

Just my two cents...  Smiley

Aw George, you're breaking my heart!

I know you're the expert, but I went ahead and sent photos to Joey's connection.

I will try to followup and post what he has to say about it.

Dear Cathy,

     I'm sorry, I didn't notice it was just core-drilled. George is 100% correct. You'd just be throwing good money after bad.
Best,
Joey

Cathy,

Are you certain this is tourmaline? It looks a lot like Fluorite from the photos.

Fluorite has a specific gravity between 3.175 and 3.184. You are exactly in the middle of this range.  It is also much softer and more fragile than Tourmaline, making it extremely tricky to hollow out effectively. Core drilling is a safe compromise!

If it is fluorite, you should be able to buff it up with a little toothpaste (white paste, not gel) on a clean cloth, and several hours worth of elbow grease!

Hi Tom,

I am not certain it's tourmaline - I didn't realize fluorite was a possibility. I will try that!

thanks,
Cathy
