關於我們
After I got my PhD in crystal physics in 1992, crystals have been a part of my career and life. Crystals are very useful in industry, but now we are exploring another aspect of crystals: their beauty and singularity. Thank you for your support and patronage as we continue to appreciate the natural allure of crystals.
