Top 3 Things You Should Know Before Buying Alexandrite
Alexandrite is a variety of chrysoberyl for its color-changing phenomenon. In fact, gemstone experts like to call it 'emerald by day, ruby by night.' So, an alexandrite appears bluish-green in daylight and purplish-red in incandescent light. However, there are other color-changing chrysoberyls as well, but the only thing that makes an alexandrite different from them is the impurities. Alexandrite contains impurities of iron, chromium, and titanium, but the proportion of chromium and beryllium is never present in equal amounts, which causes color-changing properties. So, if you're planning to buy an Alexandrite for yourself, you should already be aware of the things listed below.
