PostPosted: Jan 01, 2020 15:52    Post subject: A blue obelisk that I'm not sure what it's made from  

I'm a newbie to the gem/crystal hobby. I ordered this from China on eBay.

The seller says its Tanzanite? The actual ad read:
"114g Rare Tanzanite Fire Elestial Monatomic andara Crystal Arcturian point" HUH?

I only spent around $12 (including shipping) I think for it, so I'm not out much. But I would like to know what it's made of. I've looked around the Internet, and see similar images of what I have, but some are calling them "Siberian quartz" others call it "Blue Aura Quartz" and yet other calls it "smelt quartz". It's about 4" tall by 1" wide.

Any ideas what I have here? I have a few other crystals I was hoping someone could tell me if there genuine or a fake, but wanted to start with this one. Thanks.

Artificial glass. Quartz sand may well have been melted as one of the ingredients in the glass mix, but that‘s as close as it comes to "quartz" of any kind. Probably worth $12 as a pretty decoration, but it won‘t make too many mineral collectors excited.

General advice to gem and mineral "newbies": Before shelling out real money for rubbish(?) on e-bay, join your nearest mineral club and take advantage of the knowledge of more experienced members. And visit mineral shows, where you can handle the offerings before purchase, talk face-to-face with the sellers and other enthusiasts, comparison shop. Most people will be happy to share their knowledge, and it‘s a whole lot better experience that shopping anonymously on line.

I fully and completely agree with Alfredo. Colored glass.......

I guess my wish for this new year, on this website, would be that mineral enthusiast, newbies and novices, do some due diligence with self-education before buying anything.

For the purchase of mineral specimens, ebay can be a potentially dangerous site for novices to start out on without knowing exactly (!) what they are spending their money on.

Happy New Year To All, Bob

Genuine or fake? More a genuine fake. There is a lot of such specimens coming out of Chinese labs but never out of the ground. They are not naturally formed by nature. The silly names are a huge hint these are made for the new age market where size and colour really sells trash. If its cheap and too perfect its 99.99% certainly man made. Some are lab grown quartz crystals which are then surface coated to get metallic, rainbow and other colour effects. Its annoying for many as they are rarely labelled honestly. Anything coming from China unfortunately these days comes with the doubt of authenticity.

So buy with that knowledge. As a trinket you got a nice curio I guess; it would look nice on a window sill. But it does not contain mystic energies or will not be an investment piece. Do everyone a favour and put a label on the underside that it's artificial, so whoever ends up with it has an honest label to start with. Would probably look great in the garden too.

Hi to everybody!
Either coloured artificial glass or synthetic quartz! Synthetic quartzes are also coloured in every colour you wish, including intensive blue which is never found in nature!

"114g Rare Tanzanite Fire Elestial Monatomic andara Crystal Arcturian point"
Let‘s study this description:

114g = a factual statement of the weight, probably true.
Rare = a matter of opinion
Tanzanite = gemstone with the composition and crystal structure of zoisite, which this is not.
Fire = huh? Oh well, fire was perhaps involved in making it.
Elestial = meaningless word used for marketing purposes
Monatomic = meaningless word used for marketing purposes
andara = https://www.mindat.org/min-39945.html - marketing name for glass
Crystal = perhaps, but more likely glass, which is not crystalline
Arcturian = the alien race from Star Trek? or from the star Arcturus? credibility stretched thin
point = indeed true; it has a point.

Oh well, guess it'll make a good paper weight or yes, on the window sill. Thanks for the ID on it everyone.
