Description from the seller
A spectacular, rare, and magnetic piece
This unique specimen brings together three Herkimer Diamond crystals perfectly interlocked, forming a natural composition of rare elegance. The synergy of the two-ended shapes, crystalline transparency, and internal light play offer a breathtaking aesthetic. Each crystal seems to have found its place, as if shaped by an invisible hand at the heart of the Earth.
Characteristics:
• Total weight: 18.00 carats
• Dimensions: 25.6 × 18.7 × 11.2 mm
• Origin: Pakistan
• Shape: Naturally interlocked triple biterminated
• Clarity: Very good transparency with characteristic inclusions
• Color: Colorless, natural luster
• Treatment: None – 100% natural
Note: A Herkimer “grouped” as clean, balanced, and well-formed as this is a true treasure for any discerning collector. An exceptional showcase piece, both sculptural and authentic.
Why the name “Herkimer Diamond”?
The name “Herkimer diamond” is used to describe this particular type of double-terminated quartz, originally discovered in Herkimer County, New York. Today it is used more broadly to refer to crystals possessing the same unique qualities, regardless of their origin.
