Bulk Treated Mixed Crackle Quartz- 1kg (approx. 70 stones)

Approximately 70 tumbled crackle quartz stones supplied by weight at 1kg — a practical buying quantity for display bowls, crystal arrangements, retail stock, or craft projects.

What This Pack Contains

1kg gives approximately 70 individual stones — enough to fill a display bowl, stock a retail tray, or build a complete crystal grid with plenty to spare.

Tumbled stones have a smooth, rounded finish from the polishing process — sharp edges removed, natural colour and surface quality brought forward.

The mixed format provides natural variation across the 1kg — no two stones are identical in pattern, tone, or size, giving any display a lively, non-uniform quality.

Buying by weight is economical for regular users — the per-stone cost is significantly lower than purchasing individually.

Tumbled Natural Stone, 1kg

Clear quartz is heated and then rapidly quenched to create an internal network of fractures, then dyed in vivid colours. The internal crackle structure catches and scatters light, giving each stone a sparkling, mosaic-like interior. The process combines a genuine natural mineral with controlled colour treatment. Supplied as tumbled and polished stones, approximately 70 pieces per 1kg. Individual stone size varies — confirm approximate size range from the product specification.

Use and Storage

Use in a display bowl, on a crystal grid, as meditation stones, as a craft material, or as loose retail stock. Rinse before use. Dry thoroughly. Store in a dry container. Approximately 70 stones per 1kg, though the exact count varies with individual stone size.

Tumbled Stones and the Lapidary Trade

The tumbled stone trade has its modern origins in the mid-20th century, when rock polishing became accessible to hobbyists and the demand for affordable, attractive natural stones grew into a global market. The treatment of some stones — particularly agate — has been a standard and disclosed practice in the lapidary trade for over a century, extending the colour range available beyond what natural formation alone produces.

Common Questions

Are these stones natural or synthetic?

Natural stone, tumbled and polished. Some varieties use natural stone that has been colour-enhanced — the mineral itself is natural, the colour may be treated. Confirm treatment details from the product specification.

What size are the individual stones?

Confirm from the product specification. Tumbled stones in 1kg lots are typically 2 to 4cm per piece, though this varies by stone type.

Can I sell these individually in a retail setting?

Yes — 1kg lots are commonly purchased by crystal retailers to bag and price individual stones at retail.
