晶及其石英岩类玉石是中低档宝玉石，虽比不上钻石、红蓝宝石的高贵，但在加工中如果构思巧妙而且加工精细，同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。

Alumina also has two doable constructions at area temperature, α-alumina (corundum) and β-alumina. click here Other binary crystals exhibit various constructions at distinct temperatures. Amongst the most complex crystals are those of silicon dioxide (SiO2), which has seven various buildings at different temperatures and pressures; the commonest of those buildings is quartz.
