Man-Made Alexandrite Gemstones
Alexandrite are amazing gemstones for jewelry,because faceted gems undergo a dramatic color change in different types of light.In warm indoor incandescent or candlelighting,this gem is a rich purplish red color.In bright daylight,it is blueishgreen.Alexandrite have this color change because it includes chromium,whichhave different absorptivity to different light.Our lab created alexandrite,like natural alexandrite,is a member of the chrysoberylfamily which has the chemical composition beryllium aluminum oxide.In other words,our lab created alexandrite gemstones are chemically identical to alexandritegemstones mined naturally.Because when buying lab alexandrite,because many dealers indiscriminately use the term for imitations(such as color-change corundum).The imitations have very little color change effect and the color is light babyblue in bright daylight,because they contain less element than true lab createdalexandrite.The rate of our lab created alexandrite changing in color is 100%.In bright daylight,ourlab created alexandrite is green with slightly blue,the color is the samewith the one of the oriental emerald.In warm indoor incandescent or candle lighting,our lab alexandrite is red with slightly purple.The two colors in differenttypes of light are so beautiful that everyone will be stuck on them as soon ashe saw our lab created alexandrite.Our alexandrite rough is cut in Hong Kong,where the great care is taken to producea facted gems which offers a full color change as one moves between warm indoorlighting to the full specrum of natural sunlight.Our lab created alexandrite gemstoneshave higher perfection than is usually seen in natural stones.We are ableto offer them at a small fraction of the cost of comparable natural stones.We are proud of our created alexandrite and believe it to be the best laboratorygrown alexandrite currently on the market.
