AI-assisted summary

Description from the seller

NATURAL TURQUOISE PENDANT IN SILVER 925 (TIBETAN TURQUOISE)

Unworn shipment – Strong mineralogical character

1. General Description
Natural Tibetan turquoise pendant in teardrop cut, with intense black matrix of the “spiderweb” type and high-contrast blue-green zones.
Piece with a strong visual personality and organic aesthetics.
Not a uniform industrial turquoise: it is a mineral with visible geological character.
Unworn shipment from old stock.

2. Measurements and Weight
Total weight: 10.65 g
Approximate size: 2.8–4.7 cm including the bail
Generous thickness, well-proportioned cabochon.

3. Mineral Identification
Mineral: Natural turquoise
Crystal system: Triclinic
Color: Blue to blue-green with black matrix
The internal texture and irregular distribution of the matrix are consistent with natural formation.

4. Chemical Formula
CuAl6(PO4)4(OH)8·4H2O
(Hydrated copper-aluminum phosphate)
Copper is responsible for the characteristic blue tone.

5. Hardness and Density
Hardness: 5–6 on the Mohs scale
Theoretical density: 2.6–2.9 g/cm³
The total weight is consistent with a solid piece in 925 silver and a natural mineral cabochon.

6. Visual/Geological Reading
A well-integrated, ramified black matrix is observed within the blue mass.
No artificial repetitive pattern or typical pressed resin distribution.
Color variations and internal microcracks are typical of natural material.

7. Mineral History
Turquoise has been used since Ancient Egypt, Persia, and Tibet as a protective stone and status symbol.
In Tibetan and Asian regions it was a ceremonial and spiritual element.
Today, access to good-quality natural turquoise is significantly rarer than decades ago.

8. Mounting and Craftsmanship
Mounted in 925 silver (92.5% pure silver).
Visible 925 stamp on the structure.
Closed bezel protecting the cabochon.
sober artisanal work, focused on highlighting the mineral.

9. Articulated Clip Hinge (Brand Signature)
Clip hinge (articulated trumpet/funnel).
Better drape on the chest.
Prevents the piece from turning to display the back.
Allows use with thick chains.
A distinctive, uncommon element compared to standard settings.

10. Authenticity and Tests Performed
– Loupe inspection (coherent internal structure).
– Weight control.
– Observation of an integrated, non-superficial matrix.
No certificate, but gemologically analyzed by experts.
In the general market there are many stabilized, reconstituted, or dyed turquoise pieces.
This piece shows no plastic appearance or printed matrix.

11. Condition and Provenance
Unworn shipment.
From old stock.
No structural knocks.

12. Scarcity, Production, and Market (Version 0.6)
Quality natural turquoise production is low and in many areas is regulated or effectively halted.
Meanwhile, the general market — online platforms, physical stores, and other sellers — is saturated with imitations, pressed resins, and treated material.
Materially impossible that, with limited production, large volumes of “natural turquoise” appear daily at low prices.
This situation yields a clear consequence:
The authentic piece with real rough material appreciates as a tangible asset and a hedge against artificial oversupply.

13. Gemological Curiosities
Much of modern turquoise on the market is stabilized with resins to harden it.
Completely natural, untreated, and undyed turquoise is increasingly rare.
The well-defined natural “spiderweb” pattern is highly valued by collectors.

14. Acknowledgment of Origin
Each piece comes from the human effort of miners working in challenging conditions and increasingly limited deposits.

15. Care and Preservation
Avoid perfumes and chemical products.
Do not soak in water for long periods.
Clean only with a soft dry cloth.

16. Conclusion
A piece with character, visible natural structure, and a solid 925 silver mount.
Authentic examples, especially mounted in 925 silver, are becoming rarer, reinforcing their collector interest and potential for value appreciation.
Choosing an authentic piece is not just a purchase; it’s a conscious decision that combines beauty, judgment, and real value.
