No — Herkimer diamonds are double-terminated quartz crystals, not carbon diamonds. They earned their name from their exceptional clarity and naturally faceted form, which gives them a diamond-like brilliance. What makes them truly special is that they emerge from the earth with 18 natural facets and two pointed ends, requiring no cutting or polishing. They formed over 500 million years ago in the dolomite rock of Herkimer County, New York, and only crystals from this region can authentically be called Herkimer diamonds.

Yes — Herkimer diamonds score a 7 on the Mohs hardness scale, making them harder than most popular gemstones and well-suited for daily wear in necklaces, earrings, and bracelets. They're more durable than moonstone, labradorite, and opal. For rings, a protective setting is recommended since the crystals' natural double-terminated points can be vulnerable to sharp impacts. With reasonable care, Herkimer diamond jewelry will last a lifetime.

Andrea draws on every technique available — fabrication, wire work, casting, and assembly — to build pieces where no single element is recognizable in the final design. The Minimalism collection uses the highest quality and clarity Herkimer diamonds set in sculptural silhouettes of 14k gold, gold filled, and sterling silver. Each piece is one of a kind — handcrafted once, sold once, never repeated. Most Herkimer jewelry on Etsy uses simple wire-wrapping on raw crystals. Andrea's work is architectural, treating each crystal as the centerpiece of a fully designed composition.

Herkimer diamonds are associated with the crown chakra and are considered one of the most powerful quartz crystals for clarity, amplification, and spiritual attunement. Their double-terminated form is believed to receive and transmit energy from both ends simultaneously, making them prized for meditation, energy work, and as amplifiers for other stones. Many wearers are drawn to Herkimer diamonds for this combination of visual brilliance and energetic resonance — a stone that connects clarity of mind with clarity of light.

Clean with warm water, mild soap, and a soft cloth — avoid ultrasonic cleaners and harsh chemicals. Store each piece separately to prevent scratching against harder gemstones or metals. Remove jewelry before swimming, showering, or applying lotions and perfumes. Herkimer diamonds are naturally clear and brilliant, so a gentle wipe is usually all they need to restore their sparkle. The metal settings (14k gold, gold filled, or sterling silver) each have their own care needs — sterling silver may develop a natural patina over time, which some wearers love and others prefer to polish away.
