Amethyst Druzy Butterfly Carving

This is a small, carved Amethyst druzy specimen shaped into a butterfly. It features a dense cluster of natural crystal points across the wings, with a gradient of soft lavender to deeper violet tones and a visible quartz matrix backing.

Key Features

Formation: Druzy crystal growth over a quartz matrix

Color: Light to mid-purple with subtle zoning

Crystal Habit: Small, well-formed terminations with reflective faces

Finish: Polished/cut base for freestanding display

Shape: Butterfly carving (lapidary-shaped)

Dimensions

Approx. Size: 6.8 × 4 cm

Weight: 43 g

Geological & Scientific Notes

Amethyst forms when silica-rich fluids crystallise within cavities in volcanic rock. Over time, layers of quartz develop, with trace iron impurities giving rise to the characteristic purple coloration when exposed to natural radiation.

The druzy surface on this piece is composed of many small, euhedral crystals. These tightly packed terminations increase light reflection, producing the natural sparkle visible across the wings.
