Spectrolite was found in 1941 when we were building a defence line on the eastern border. The mining of the gemstone started on a small scale, increasing in the 50s.
The fascination of spectrolite bases on its richness of colours and changing tones. The colours have all the shades of spectrum reflecting the rich hues of Finnish scenery - from golden browns to darkest blue and the colours of the rainbow, northern lights and butterfly wings. The play of colours is due to interference of light waves in the layers of material where light is reflected.
Spectrolite quarried from the rugged bedrock of Ylamaa, Finland is a precious gemstone which meets the three important basic requirements: beautiness, hardness and rarity. Spectrolite is a labradorite feldspar, a member of the albite anorthite series with approximately 55 % anorthite.
Facts:
- Mohs hardness: 6.0 to 6.5
- Mineral: Feldspar
