Description from the seller
Natural Blue Topaz Pendant in Rough Form in 925 Silver – Crystal in Natural State
1. Overview
Pendant composed of a blue topaz crystal in its rough, uncut, unpolished state, preserving its natural morphology entirely. This type of piece has an authentic mineral character, far from a commercial finish, where the stone retains its original geological identity.
The blue tone, clean and luminous, together with its irregular structure, offers a direct and honest aesthetic, highly valued by collectors and by those seeking pieces with their own personality.
2. Measurements and weight
Weight: 4.69 g
Approximate measurements: 2.5 × 1 × 0.5 cm
3. Mineralogical identification
Topaz – blue variety
4. Chemical formula
Al₂SiO₄(F,OH)₂
5. Hardness and density
Hardness: 8 on the Mohs scale
Density consistent with the observed weight
6. Visual and geological reading
Rough crystal with irregular surfaces typical of natural growth, with translucent zones and coherent internal inclusions. Natural fractures are evident without artificial manipulation.
7. Mineral history
Topaz has been valued since ancient times as a symbol of clarity and protection. In its natural, uncut form, it retains a special appeal due to its authenticity.
8. Mounting and artisan work
Set in 925 silver (92.5% pure silver), verified by XRF analysis, ensuring metal consistency from origin.
Claw system manually adapted to the crystal’s irregular shape.
9. Hook (bail)
Solid, functional, and balanced bail, with good fall and stability.
10. Authenticity and tests
Verified by:
Structural observation
Coherent inclusions
Weight consistent with volume
Material behavior
(not certified, but with own gemological analysis)
Blue topaz is usually treated (irradiation + heat), a standard and accepted practice in gemology.
11. Condition
Excellent condition
Unworn batch
12. Probable provenance
Brazil (not certified)
13. Market, scarcity and investment
Rough pieces mounted are less common than cut ones, offering real differentiation.
Authentic specimens, especially in large formats and mounted in 925 silver, are increasingly scarce, reinforcing collector interest and potential for value appreciation.
14. Gemological curiosities
Natural topaz is usually colorless. Blue is the result of controlled treatment, accepted in gemology.
15. Origin acknowledgment
Extraction under demanding conditions where human labor plays a decisive role in obtaining the material.
16. Batch and context
Piece from an unworn batch, selected based on material coherence and aesthetics.
17. Conclusion
Authentic piece with clear mineral identity and differentiated aesthetics compared to standard commercial products.
Seller profile
A collector and entrepreneur with more than 40 years of experience, with technical training (engineering), an MBA, and marketing specialization.
My approach combines rigorous analysis, aesthetic criteria, and market insight, selecting pieces that stand out for authenticity, material coherence, and real value.
My dedication to the world of minerals did not start as a professional activity but as a deep personal interest. It is an area I always wanted to develop and which today forms part of my daily life as a natural extension of my curiosity and judgment, allowing me to handle each piece with special care and respect for its origin.
I work exclusively with pieces that meet clear quality standards, applying verification protocols based on structural observation, weight, material behavior, and, when applicable, comparison with instrumental analysis.
For silver pieces, I use 925 material (92.5% pure silver) sourced from controlled batches and verified by XRF analysis, ensuring metal coherence from origin. In a market where counterfeits are common, this control adds an extra layer of security for the buyer.
Each piece is presented with a professional approach, combining technical information, context, and a clear reading of the object, avoiding exaggerations and prioritizing transparency.
My goal is not only to sell but to offer carefully selected pieces, intended for aesthetic enjoyment as well as for those who value authenticity and market coherence.
