What colour is Azure spar?
Azure spar refers to a group of minerals known for their intense blue shades, ranging from sky blue to deep blue or bluish-grey. The term is not precise and has been used for several stones, most notably lazurite (the main component of lapis lazuli) and azurite, as well as lazulite, hauyne, and turquoise. These minerals are valued for their colour and are found as opaque, translucent, or transparent stones.
Where does Azure spar come from?
The name 'azure spar' is a commercial and informal term that became partly obsolete over time. It was used to group together blue minerals with similar appearances. In the early 1800s, Robert Jameson included stones like hauyne and turquoise under this label. The word 'azure' points to the blue colour, while 'spar' is a general term for non-metallic minerals with a crystalline form.
How is Azure spar made?
Azure spar is not a single mineral but a name for several blue stones. Lazurite is a sodium aluminosilicate with sulphate, azurite is a copper carbonate-hydroxide, lazulite is a hydrous phosphate of iron, magnesium and aluminium, hauyne is a sodium and calcium aluminosilicate, and turquoise is a hydrated phosphate of aluminium and copper. These minerals are found in nature and are not synthetically made for this purpose.
Where Azure spar is used
These blue minerals have long been used as ornamental stones in jewellery and decoration. Lazurite, especially as lapis lazuli, is highly valued for its deep blue colour. Azurite has been used as a pigment in painting, particularly in tempera and icon art, though it is less common as a gemstone due to its fragility. Turquoise has been a popular semi-precious stone since ancient times. Lazulite and hauyne are more rarely used in jewellery because good specimens are uncommon.
