Description:
Emerging from the mineral rich region of Waziristan, Pakistan, this unique trio of Herkimer Diamonds presents an exceptional study in clarity, structure and reactive behaviour. Each crystal displays the sharp, naturally formed geometry characteristic of true Herkimer quartz, with clean faces, precise terminations and internal transparency that allows light to travel freely through the structure.

What elevates this ensemble beyond the ordinary is the coexistence of two distinct ultraviolet reactions within a single group. Two of the crystals reveal rare golden fluorescence under UV light, caused by internal hydrocarbon films that ignite in warm tones of amber and honey. The third specimen contrasts this behaviour by exhibiting petroleum based fluorescence, producing a deeper, cooler glow that reflects a different internal chemical environment. Together, these responses form a dialogue of light, where warmth and depth alternate depending on the crystal and the angle of illumination.

Under normal light, the trio appears refined and balanced, with each piece maintaining a clean, colourless body and subtle internal features that hint at their hidden complexity. When exposed to ultraviolet light, however, the crystals transform dramatically. Internal zones awaken, filaments and chambers become visible, and the specimens reveal an entirely different identity, one rooted in geological processes that trapped organic material millions of years ago.

This combination of clarity, architecture and dual fluorescence is rarely encountered in a single offering. Rather than isolated curiosities, these three Herkimer Diamonds complement one another, forming a cohesive set that showcases the full expressive range of hydrocarbon bearing quartz from this locality.

Specifications:
• Weight: 0.69 g total
• Weight in carats: 3.45 ct total
reference
• Origin: Waziristan, Pakistan
• Mineral: Biterminated Herkimer diamonds
• Formation: Hydrothermal growth
• Terminations: Naturally double terminated on all three crystals
• Transparency: High clarity with visible internal features
• Lustre: Vitreous
• UV reaction: Two crystals with golden hydrocarbon fluorescence; one crystal with petroleum based fluorescence
• Colours: Colourless in daylight; golden and petroleum reactive tones under UV
• Treatment: None

Notable Points:
• Trio of Herkimer Diamonds with complementary UV behaviour
• Two specimens displaying rare golden hydrocarbon fluorescence
• One specimen exhibiting classic petroleum based fluorescence
• High clarity allowing clear observation of internal reactions
• Sharp natural geometry with well preserved terminations
• Distinct internal chemical environments within a single set
• Strong visual transformation under ultraviolet light
• Clean daylight appearance without visible colour masking
• Geological authenticity typical of Waziristan material
• Balanced ensemble suited for advanced mineral collections

Collector’s Interest:
Trios of Herkimer Diamonds showing multiple types of hydrocarbon related fluorescence are exceptionally uncommon. The presence of both golden and petroleum reactive behaviour within a single set offers collectors a rare comparative opportunity, highlighting how subtle internal differences can dramatically alter optical response. This ensemble is particularly appealing to advanced collectors of UV reactive minerals, as well as those focused on geological diversity within a single locality.

Lapidary Interest:
While technically suitable for specialised lapidary approaches, these crystals are best appreciated in their natural state. Preserving the original terminations and internal structures maintains both their scientific and aesthetic value, especially considering the rarity of their combined ultraviolet reactions.

Shipping and Handling:
All orders are shipped by UPS express or National Express.
• Dispatch time: within 1 to 2 business days after payment confirmation to catawiki
• Transit time with Express service: up to 3 business days within europe and worldwide
• A tracking number is always provided

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. Each order is handled with professional care from selection to dispatch, ensuring a smooth and trustworthy process.

Customs and import taxes:
Any customs duties, import fees, or local taxes applied by the destination country are entirely the responsibility of the winning bidder. These charges are not included in the auction price or shipping cost and are determined by the buyer’s local authorities.

Guarantee and resolution:
Customer satisfaction is a priority. In the event of any issue, such as loss, damage, or discrepancy, please contact us immediately through Catawiki’s messaging system. We will always find a fair and suitable solution, including refund, replacement, or other commercial arrangements whenever justified.
