What is the difference between azurite and lapis lazuli
A person who is poorly versed in natural minerals or is not at all interested in jewelry can often confuse two completely different gems - azurite and lapis lazuli. Yes, the names of the stones are very similar in their sound, but in fact, only this consonance unites them. Gems still differ in their physical characteristics and even appearance.
What is the difference between lapis lazuli and azurite
First, if you look closely at the minerals, you will notice that, despite the same color scheme, their shades are still different. Lapis lazuli has a more muted and soft blue color, even and calm, while azurite has a sharp, rich bright color. In addition to the shade, albeit slightly noticeable, the stones also differ in their physical and chemical characteristics:
Characterization | Lapis lazuli | Azurite |
Line color | light blue | pale blue |
Transparency | always transparent | there are opaque crystals, but the light shines through |
Hardness | 5,5 | 3,5-4 |
Cleavage | implicit | perfect |
Density | 2,38-2,42 | 2,5-4 |
Main impurities | spars, pyrite, sulfur | copper |
As can be seen from the comparative characteristics, minerals have a lot of differences. However, they are often confused and mistaken for one gem. In fact, both stones are used in the jewelry industry, however, lapis lazuli, due to its high hardness, still outperforms azurite a little.
In addition, there is another feature: the thick blue color of azurite is not stable. Over time, it can acquire a barely noticeable greenish overflow.
When buying jewelry with a deep saturated stone, it is better to check with the seller what exactly is in front of you. As a rule, all information should be contained on the product tag if you yourself doubt the authenticity of the jewelry.
