Identification clues
Look for a blue body, sometimes interrupted by white patches or small metallic gold-coloured flecks. Lazurite supplies the characteristic blue; calcite and pyrite are common companions. Not every piece shows all three clearly.
Mineral facts and formation
Lapis lazuli is a rock, not a single mineral species. Its ingredients and their proportions vary, so an attractive blue colour is only the beginning of an identification.
Lookalikes and useful comparisons
A blue stone is not automatically lapis. Record the distribution of blue, white and metallic areas before comparing a reference specimen. A dyed material can imitate colour; a photograph cannot establish treatment history.
Care for a display specimen
Use gentle warm soapy water briefly and dry carefully. Avoid steam, ultrasonic cleaning and strong chemicals. Dyed or waxed pieces may need extra care, so ask the supplier about treatment.
Look a little closer
Try this observation.
Make a three-column note: body colour, pale patches, metallic flecks. Record “not visible” when a feature is absent instead of assuming every lapis must show it.
Are the gold-coloured flecks gold?
The familiar metallic flecks in lapis are pyrite. Their presence is a clue to record, not proof that an unknown blue stone is lapis.
