How to Identify Blue Aventurine
- 1). Pay attention to the appearance of the stone. Blue aventurine looks similar to jade or quartz crystal, but in a blue color. The appearance of the stone is one of the main identifying factors.
- 2). Check the stone hardness. Blue aventurine has a hardness of 7 out of 10, making it a tough crystal. The material is harder than glass, which has a hardness of about 6, so in a scratch test it will leave a light scratch on the glass. The scratch will look faint, but will show up.
- 3). Look at the fracture type. According to Mineral Miners, a blue aventurine has a conchoidal fracture. This means that the way the stone breaks is not following a natural separation pattern, but rather an odd curved pattern or similar odd-looking breakage. This is a common type of fracture seen in stones such as quartz and flint.
- 4). Consider streaks in the color. The base color of quartz is white. Since blue aventurine is a quartz crystal with other materials that create color, the streaks that are typically seen across the material are white.
