Can anyone identify this stone?


#1

I fell in love with the stones in this bracelet and am desperate to
find out what they are: slider-2

The product details mention that it’s reconstituted semi-precious,
plus it’s made in China, so it’s likely that the factory made up a
fake semi-precious stone just to achieve these colors. I’m hoping
they based it off something that naturally exists " does anyone know
what it might be?

Any ideas would be greatly appreciated!

You could easily create a similar bracelet with the “rind” of
Larimar. It wouldn’t surprise me if this was exactly what was
reconstituted here. The darker matrix material has a lower hardness
and is difficult to polish so sealing/impregnating it with something
would be needed to create a smooth polish like your bracelet. the
"rind" material could be purchased for a fraction of the cost of
clean Larimar.

Shattuckite? A copper bearing mineral most likely.

Looks like zoisite maybe.

Hi,

Now not holding it in my hands, it looks to be chysacola (I know I
spelled it wrong I blame age for that) That is in matrix mixed with
other things coupons near copper mines. A more quartz based matrix.
BUT and here is the big BUT, Many many stones that come from China
are fake, or have been reconstituted from a jumble they press
together. Something to on the look out for is Chinese turquoise. We
use to call it plasticized turquoise dust.

Aggie currently fighting the A/C repair people who don’t carry
ladders and are afraid to go up to where the a/c unit is. So
sweltering in Florida!

That is Larimar, from the Dominican Republic.

We are miners-cutters-manufacturers for 24 years out of Lima Peru
with USA office. The stone needs X-ray diffraction chemical analysis
foridentification. Many call chrysocolla we mine “turquoise” in Peru
referring only to a color. We had our new mining of azurite
-malachite/azuriet-maalchite-chrysocolla near Arequipa analyzed and
its premium stabile rough and cut kilos we are selling. Another
stone blue aragonite looking like larimar but stabile for cutting we
had to use chemical analysis testing. If you need such testing
contact me at @Lee_Horowitz or via Peru Blue Opal - Welcome
Also see us with GIA

Maybe that stone is a low grade slice of Larimar?

I personally dont think it is Larimar… I have never seen Larimar
unless it has been dyed with the purple. The Chinese are dyeing quite
a few types of stones.


#10

I agree that it’s NOT Larimar, which is a pale sky blue, often with
some white, and occasionally with red/brown dendrites. It’s probably
a composite of several stone tailings that have been dyed and
epoxied together. I’d try soaking one in acetone to see if it falls
apart.

Thanks, everyone! I think I’ll need to go to some gem shows in
person and hunt down all your suggestions to make sure I can find the
specific colors.

My sense is that it is gem debris stabilized with resin. While
living there Iwould see a fair bit of it in the markets and on the
street. In this case, Iwould guess amethyst (probably synthetic)
together with dyed howlite (as turquoise), or something similar.

Sometimes it’s difficult to recognize gem debris stabilized with
resin, now that the lapidary trend of including matrix seems
pervasive.

A ribbon turquoise cabochon caught my eye, but the finish on it felt
slightly tacky. Is that almost sticky type of surface indicative of
resin stabilization?


#14

My thought all along is that it was turquoise that has been
stabilized of course but it IS difficult with just a picture!


#15

I asked a good friend of mine that handles this type of stone what
it is.

Is the picture attached what you are asking about? if so it is
Chrysocolla and red cuprite. It is found around Bisbee Az. and some
deposits in central Az.

Aggie It is now 8 days of no A/C here in Orlando. I want a grown up
to fix the unit not some kid that is afraid to get their fingers dirty.


#16

If stabilized chrysocolla and turquoise, if stuck with a hot needle
or pin one can tell via smell the opticon used in stabilizing. In
peru wherewe mine for many years and cut peruivians do not stabilize
stones ortreat them. Th dying and stabilization of chrysocolla and
blue opal are done outside the country i. e. India, China, etc

As a Gemologist, I would not take a guess, I would need to do
something scientific to identify. There have been some interesting
guesses, and they seemed pretty sure, and they were 100% wrong. One
of pet peeves, is the guessing that happening from pictures on
Facebook. And, myself and other get attacked by people who are wrong
when a person tries to educate.


#18

I wouldn’t expect so. Resin is hard, like an epoxy. Wax is common, as
a coating to improve the appearance. Maybe something like that.


#19

I’m no Geologist, but my guess is Peruvian Opal.

Some years ago a Russian friend of mine happened to be in Peru when
a small run of top color pink opal came into the market there. So he
bought it all and is sitting on it to this day (as far as I know). I
was lucky enough to be in Bangkok at the same time it was.

It was such a beautiful soft pink. Looked like ice cream. :slight_smile:
