Amethyst druzy heart carving

This is a carved amethyst druzy specimen shaped into a heart, featuring a natural mix of purple tones rather than a uniform colour. The surface displays medium to deep violet crystal points with areas of lighter lavender and near-clear quartz, all set within a visible agate/quartz matrix border.

Key Features
Material: Natural amethyst (quartz variety)
Formation: Druzy crystal growth over agate/quartz matrix
Color: Mixed tones – medium to deep purple with lighter lavender and clear quartz areas
Crystal Habit: Larger, well-formed terminations with a glassy lustre
Finish: Polished edges with raw druzy crystal face
Shape: Heart carving (lapidary-shaped)

Dimensions
Approx. Size: 5.7 × 5.5 cm
Weight: 88 g

Geological & Scientific Notes
Amethyst is a variety of quartz formed from silica-rich fluids within cavities of volcanic rock. The variation in colour seen in this piece is due to differences in iron content and exposure to natural irradiation during formation.

The druzy surface consists of well-developed crystal points (euhedral terminations), giving the piece a more textured and dimensional appearance compared to finer druzy specimens. These crystals formed inward from the cavity walls, creating the sparkling surface.

The outer edge shows banded agate and quartz matrix, with natural mineral inclusions and subtle earthy tones. This banding is a typical feature of geode formations and highlights the natural growth environment of the specimen.

Care Instructions
Handle with care to avoid chipping the crystal points
Clean gently using a soft brush or compressed air
Avoid water exposure where possible, as moisture can settle between crystals
Keep out of prolonged direct sunlight to help preserve colour
Store separately to prevent scratching or damage from harder materials
