Herkimer Diamond • Rare GOLDEN UV Fluorescence • 11.8 ct - Height: 17 mm - Width: 11 mm- 2.36 g - (1)

Description:
Emerging from the mineral rich landscapes of Waziristan, this Herkimer Diamond reveals itself as a small natural architecture of light and stillness, a crystal that preserves within its form the meticulous gestures of hydrothermal crystallisation. Its geometric faces open into clarity windows that intersect with inner channels and microchambers, creating a visual depth that immediately captures the eye. Under natural light the quartz maintains a luminous transparency, alive with reflections and the classic presence that defines true Herkimer formations.

Yet it is under ultraviolet light that the specimen unveils its most unusual signature. Instead of the common petroleum blue so frequently encountered in Pakistani examples, a warm amber golden glow emerges from within, a rare fluorescence caused by delicate hydrocarbon films trapped inside the crystal. These tones are subtler, less common, and lend the piece a camaleonic personality that reveals itself only to those who understand the secrets awakened by UV light.

Weighing 11.8 carats, this specimen balances clarity, structure and character, becoming a singular crystal that unites the purity of quartz geometry with the discreet alchemy of reactive inclusions. A piece that transforms, that ignites, that reveals hidden worlds without ever losing the elegance of its natural form.

Notable Points:
• 11.8 ct hydrocarbon bearing Herkimer with rare golden fluorescence
• Naturally double terminated crystal with well defined structure and clean faces
• Internal clarity windows offering appealing light reflections
• Clear body with light inclusions that enrich its internal depth
• Warm UV reaction far less common than the classic petroleum blue
• Excellent display specimen with strong presence in a collector’s tray
• Authentic Herkimer type quartz originating from the hydrothermal zones of Waziristan

Collector’s Interest:
This specimen combines size, transparency and an uncommon optical behaviour highly valued among collectors of reactive minerals. The golden fluorescence, considerably rarer than the typical blue found in the same region, grants it a distinctive character that sets it above most Pakistani Herkimers. Its natural geometry and internal play of light further enhance its desirability in refined quartz collections.

Lapidary Interest:
Although primarily suited for a collector’s cabinet, this crystal also offers potential for lapidaries who work with natural terminations or seek to incorporate its organic UV fluorescence into creative pieces. The warm reaction under ultraviolet light adds an aesthetic dimension ideal for unique jewellery projects.

Photography and transparency:
All photos were taken under controlled light conditions, carefully selected to reproduce the most accurate natural colour of each specimen. No filters, colour enhancement, or artificial saturation were applied. The lighting setup uses a calibrated 5500K light source, which replicates neutral daylight and reveals the true tones and clarity of the mineral. Under weaker or more yellow indoor lighting, colours may appear slightly different, which is normal and expected. The purpose of this setup is to present each specimen exactly as it appears in balanced natural daylight, allowing buyers to appreciate its authentic colour and lustre without distortion.

Identification and ethics:
All specimens offered are guaranteed natural and as described. Their origin and mineral identification are provided with the most accurate and reliable information available. Every effort is made to ensure that each piece is presented with full transparency, avoiding any misleading details regarding its nature, treatment, or provenance.

Shipping and handling:
Orders are carefully prepared, with each stone individually protected and placed in a secure rigid box to ensure safe delivery. Shipments are made within 1 to 3 business days after payment confirmation, always with a tracking number provided to the buyer.
