Steam, chemical solvents, and ultrasonics should be avoided for cleaning. The old standby of a soft brush and mild soap would be safest.

Value

Value in lapis is determined almost exclusively by color, with deep, intense, blue with violet tones being at the apex. Fine grained, uniform specimens attain a smooth highly polished surface not seen in lower grades. Calcite inclusions always lower the value, but pyrite inclusions enhance it in the minds of many collectors and jewelry lovers. The quality of polish, and the artistry of fashioning are also factors in value.
