Hey everyone-
Some gem nut just emailed me about a listing in my artfire shop for a malachite necklace.  She said I should specify that the stone is man made, not natural.  I bought two of these stones at a gem show last fall, and I assumed they were natural.  Can you take a look and give me your thoughts?  Attaching a photo, along with a link to the full listing with more pictures.

Don't know about malachite, but just had a look at your offerings.
Congrats, you got a nice variety of items in your shop. Nice presentation in general. yes

What reason did he give you?
I take it that some people are just bugging the competition?

Best regards, Kurt

This was her exact email:

Hi. This & the necklace are lovely pieces, but I think you need to state that they are man-made, not natural Malachite. Sorry, but having been a gemologist for over 32 years, I get kinda peeved at people passing off imitation & synthetic stones as the real thing. Please feel free to tell me to mind my own business, lol![/i

There was a bracelet I think she saw too--it was featured ina  collection.  Bracelet pic attached.  But that's the only malachite necklace she could be talking about.

Thanks Kurt!  I don't know why she'd be "peeved" at all.  Unless maybe she thinks the stone is clay or some garbage, but it certainly doesn't feel like it, and I trusted my source when I purchased it.

The bracelet is almost certainly man-made, but IMHO the necklace is not. It is hard to tell just from a photo, but most of the artificial 'malachite' has banding that is suspiciously strong and consistent. You can see this in the bracelet, but not the pendant.

Just remember: If it is pre-fabbed chinese stuff, you need to think twice about whether or not it is natural.

That just means it is not a natural stone that has been dyed. It doesnt mean it is not artificial. Rainbow cal-silica and 'fordite' will also keep color and banding all the way through, and they are very much not natural.

I am by no means a malachite expert, but I also believe the bracelet beads to be man-made... as already stated, the banding and the color definition (contrast) in the beads looks too consistent to be all natural.  The banding in all of what I have cut changes directions more erratically as you go deeper into the stone.

Now the pendant is a different story, as it looks very much natural.  Of course, I have only cut a few pound of malachite so that is just my opinion.

I agree the pendant certainly looks like natural stone. But the beads look to be man made glass or some material like that. If it was a glass etc it would show the same color etc all the way through. But there are "arm chair experts" out there. Who will claim to be what ever makes them sound like they know what their talking about. Mal. takes a good polish but not a glass like shine(in my experience). But on the other hand. You are selling a hand made pendant (jewelry) not a mineral specimin piece. But I do know the feeling. As I've seem man made or died Howlite/Turquois being sold as real for high bucks.

Heck, I'm afraid to even try to buy turquoise these days because of all the imitations and grossly dyed colors.  And yes, I'm selling jewelry, not mineral specimens, and my pricing is based on my materials cost plus labor...we're not talking expensive products here.  I kinda doubt my $30 bracelet or pendant will be handed down as some great piece for grandchildren  to inherit, I just strive to make something affordable and pretty for someone.

And honestly, while someone may question a stone, and I may not know the answer, it really isn't feasible for me to have every single gemstone I buy tested for authenticity.  I try to use reputable suppliers, and I've purchased my share of garbage that I either don't use or sell very inexpensively with what I believe to be an accurate description of what it really is.  Finding gemstones is always a learning experience, and when I have questions I ask my supplier if possible.  But I can't always guarantee I'll get an answer, or an honest answer.

Must agree with the majority opinion here. Bracelet - probably not natural. Pendant - natural. The pendant stone appears to have some pretty typical surface characteristics that are missing on the bracelet stones.

I too agree that the pendant piece is natural, and the necklace is artificial..  bricks

For what it's worth, the small beads on the necklace look natural...  The large accent beads do not however.  A lovely design and not too big of a deal, just a matter of editing your listing.

Pendant: Natural
Bracelet: Man made.

The fakes are getting harder to detect but are becoming more prevalent with the cost of Natural malachite going up.  I remember talking to a guy at a show last year and he said Malachite was going up in price because some of the countries in Africa figured out that they could make more money smelting the stuff for copper than they could selling the stuff for gemstone use. 

How to tell Fake Malachite from real?  The banding in the fakes is more consistent and evenly spaced and doesn't have the randomness and orbing natural malachite can possess.

As for the so-called gemologist nit pick that emailed you.  If you even decide to reply you can let her know that A) You did not know the malachite was fake, and B) That you will relabel it, and C) That her input was appreciated.  Leave it at that.  If she manages to get nasty then report the abuse to the powers that be on Etsy or artfire - wherever the problem occurred and let them deal with it.  It's what you pay for is for them to deal with the non-sense so you can continue to enjoy your business.
