AI-assisted summary
Description from the seller
Overview
Open bracelet with a minimalist design in silver featuring three natural Herkimer crystals, known for their clarity and double-terminated crystal formation. An elegant, sober piece where the visual strength lies in the mineral’s purity.
2. Measurements and weight
Measurements: 7x 5x 1
Weight: 14.39
3. Mineralogical identification
Herkimer Quartz (high-purity quartz variety with natural terminations).
4. Chemical formula
SiO₂
5. Hardness and density
Hardness: 7 (Mohs scale)
Approximate density: 2.65 g/cm³
6. Visual and geological reading
Herkimer crystals are characterized by natural growth with double termination, without the need for cutting. In this piece, the original prism shapes are visible, with slight internal inclusions that confirm their natural, untreated origin.
7. Mineral history
Herkimer crystals owe their name to Herkimer County (New York, USA), where highly transparent specimens were discovered as early as the 18th century. They have historically been valued by collectors and jewelers for their perfect natural formation, which sets them apart from other quartz.
8. Mounting and craftsmanship
Open rigid bracelet in plated metal with a matte finish, designed to highlight the mineral without interference. The setting respects the natural form of Herkimer, with no artificial cutting.
9. Design and aesthetics
Contemporary, minimalist aesthetic. The arrangement of three crystals creates visual balance, adding discreet elegance and versatility for daily wear or collection.
10. Authenticity and tests
Uncut crystals with natural geometry
Irregular internal inclusions
Characteristic Herkimer transparency
Market imitations in glass or treated quartz exist; this piece shows characteristics consistent with natural material.
11. Condition
Excellent condition, from a shipment unused.
12. Provenance
Commercial-origin piece based on natural Herkimer crystals, selected for clarity and formation.
13. Market, scarcity and investment
Authentic Herkimer crystals, especially when mounted to respect their natural shape, are increasingly valued. Their combination of aesthetics and authenticity enhances interest for both jewelry and collection.
Authentic specimens, especially in well-mounted pieces, are becoming less frequent, reinforcing their potential for appreciation.
14. Origin recognition
These pieces represent the interaction between natural geological processes and human labor in extraction and selection, where origin effort is essential.
15. Care and preservation
Avoid direct impacts on the crystals. Clean with a soft cloth and no abrasive products to preserve the quartz’s natural luster and the metal finish.
16. Conclusion
A piece that blends mineral purity, minimalist design, and authenticity—ideal for personal use or collection.
Choosing an authentic piece is not just a purchase; it is a conscious decision that combines beauty, judgment, and real value.
