What mine is this turquoise from and what is the value of this squash blossom necklace?

Hello Paula,

All of the black matrix you see contains pyrite; some dark spots in the photo are exclusively pyrite. Most are mixed with the black matrix, however. Notice the quarter for size comparison. All the stones rise at least 1/8″ above their settings, and some rise as high as 1/4″ or higher. Amazing, right? 🙂 The earrings appear to have hand engraved rising suns on them (the suns are not identical, causing me to think they were hand carved, however they may have been distorted during the shaping of the petals?). I love this necklace so much, as both my folks have passed. Knowing they wanted me to have it makes me feel very blessed.

I sent you the photo in natural undirected sunlight, but I also took a couple pics in direct sunlight around 8:00 this morning, before the skies became overcast (we’re expecting freezing rain here in northwest Ohio this evening. great). If you want me to send a photo of the piece in direct sunlight, I can. The pyrite shows up better in the sun.

Much to my delight, I rediscovered the Fred Harvey bracelet my parents gave me as a child, and set it next to the necklace for you to look at as well. I had a copper one also, but I hated it, and either traded it for a plastic animal with one of my childhood friends or threw it out altogether. Regrets!!!

If you venture a guess on the value of these pieces as you try to determine the mine this turquoise is from, I’d love to hear your thoughts.

Sincerely,

Sydney

Good morning Sydney,

Beautiful sentimental treasure.

Without seeing it in person, I can’t say for sure, but I’d narrow it down to Blue Diamond, Kingman or Morenci.

We don’t appraise or give value from photos.

Enjoy ! That’s the main thing. Turquoise has a great power and feel to it.

I’m going to post the photo of your necklace on my blog so if anyone else has other ideas on the stones, they can chime in.

Paula

Dear Paula,

Thank you so much for your input, I appreciate it very much. Per your knowledge of turquoise and my further research, I am pretty sure the stones in my squash blossom necklace are from the Blue Diamond hat mine. I’m pretty happy about that. I knew it started production in the 1950’s and stopped in the 80’s. The mine is now buried under thousands of tons of rock, making Blue Diamond turquoise highly collectible today.

In the descriptions I’ve read, Blue Diamond is known for the triangular-shaped black chert, which is readily seen in the stones of my necklace. This is why I believe my stones are Blue Diamond. Plus, the pyrite is not silver colored as in the Kingman turquoise. Morenci turquoise doesn’t exhibit the black chert so recognizable in Blue Diamond. So, by process of elimination, I have concluded my squash blossom stones are Blue Diamond turquoise.

It will be interesting to read the input from your blog after you post the photo of the necklace. 🙂 I’m no expert, but as in all things, when I become interested in something, I become a super sleuth until my desire for knowledge has been satiated. I too welcome your readers’ input.

Thank you for indulging me with this sleuthing, it’s been much fun, and of course I love the products on Horsekeeping,com.

Blessings,

Sydney

Turquoise with black and white in it……..is it valuable?

Is turquoise with black and white in it valuable? Any information would be appreciated. John

Hi John,

The black is matrix which is striking and somewhat common in certain mines such as Kingman, Sleeping Beauty, and other mines.

Most rough blocks of turquoise contain splotches or veins of the mother rock in which it formed.  This can include white kaolinite which is a clay mineral. Both matrix and clay deposits can affect the color and toughness of the turquoise stone and its workability for the Native American jeweler.

In general, I would say dark matrix (black, chocolate brown, rust, gold etc.) is desirable and white inclusions, not so much because the white is associated with a more chalky consistency, therefore less tough. I’d be happy to hear the opinion of others. Paula

Navajo Tommy Singer Bamboo Coral and Treasure Necklaces

Hi Paula,

I am interested in some of Tommy Singer’s work which is displayed on your website.

Items NHS828, NH878, NH827, and the multi-strand bamboo coral.

I am wondering what percentage of the beads he uses are actually handmade/handformed by him or his family. My wife and I are building a collection, trying to stick to sole-authorship pieces.

Any information you can give me on these pieces, or any others you might have by Tommy and others would be greatly appreciated.

Thanks and best regards,

Charlie

Hi Charlie,

Thanks for your inquiry.

The 12K gold filled barrel beads that are decorated, gold, black silver are made by Tommy Singer. Also the solid sterling silver barrel beads are made by him. They are on most of his necklaces. They are his signature treasure necklace beads.

The purple and orange spiny oyster and turquoise heishi style disc beads are made by him. Also the other gemstone beads that are disc style.

The long narrow bamboo coral – I am not sure but I think not made by him.

The little sterling silver decorative spacers – I think not made by him.

The sterling silver cone ends are not made by him.

So a high percentage of what goes into his necklace is hand made by Tommy Singer or his family.

Doris and James Coriz make all the component of their necklaces, for example

These artists also make ALL of the heishi right on the “string” so to speak.

Boulder Turquoise – Native American Jewelry Materials

Boulder turquoise has a warm earthy look to it because it is Mother Earth with a ribbon of bright turquoise running through it – thus it is also sometimes called Ribbon Turquoise. The ribbon can appear and disappear in the mother rock.

Boulder Turquoise can be found in any mine, but often the rock surrounding the turquoise is too brittle or soft to polish into a cabochon or a stone for a setting.

Therefore, a few mines are noted for their production of usable Boulder Turquoise for jewelry: Pilot Mountain and Royston. Read More about US Turquoise Mines here.

What is Matrix in a Turquoise Stone?

Matrix is the term used to describe the contrasting material in a parent rock – usually turquoise.

Matrix can be thick channels or delicate fine lines like a spiderweb.

Spiderweb Matrix in #8 Turquoise

It is usually made of iron pyrite and can look like fleks, spots or distinct veins.

Some people like stones WITHOUT matrix – they are called “clear stones”.

Other people are drawn to the variations in the shapes and colors of turquoise with matrix.

Matrix can add texture to the stone as well as a bit of glimmer in some cases.

The most common matrix colors seen in turquoise are black, brown and honey.

Brown Matrix in Fox Mountain Turquoise

Honey Colored Matrix in an Emerald Valley Turquoise Bracelet

When turquoise is cut so that there is more Mother Rock than Turquoise, it is called Boulder Turquoise. So in this case the “veins” are turquoise !

So many beautiful stones to enjoy !
