A gem in the chrysoberyl family.
Changes color from Green to Red.
A durable gem.
Alexandrite is a gemstone in the family group “chrysoberyl” that changes color in different lighting. When outside in daylight, an Alexandrite stone is a green or greenish-Blue. But inside, under warm lightbulbs or by candlelight, it is a purplish-Red. This leads some to refer to it as an “emerald by day, ruby by night.”

This unique and mysterious color change is one reason couples search for an Alexandrite engagement ring. Another is that it is quite a hard gem at 8.5/10 på Mohs hårdhedsskala (diamond is a 10)! Med andre ord, “Alex” stands up to everyday wear.
What is the best color for an Alexandrite engagement ring?
Green or blueish-Green to Red or purplish-Red are the best.
Lab stones are a little more blue and a little more purple.
Imitation stones don’t change color or change to the wrong color.
Like all colored gemstones, the most important factor is color. In color-change gems, this also means how completely the stone changes from one color to another!
NATURAL ALEXANDRITE ENGAGEMENT RINGS
A top quality natural Alexandrite will change fully from Green to Red under different light sources. There will be no hints of green in the red, no hints of red in the green. The gem will appear to magically, fully transform simply by turning on a light. Natural stones with this full color change are exceedingly rare and sought after. Par skal være opmærksomme på, at naturperler af lavere kvalitet ligner mere et vandfarvemaleri, med noget lilla, der vælter over i det grønne, og omvendt.

LAB SKABEDE ALEXANDRITE FORLOVELSESRINGE
Lab-skabt Alexandrite har samme hårdhed, farveændring, og kemisk sammensætning som dens naturlige navnebror. Med hensyn til farve, en Lab-stens grønne nuance har en tendens til at læne sig mere blålig end den naturlige version. Dens røde nuance har også en tendens til at læne sig mere lilla. Ægte Lab-skabte sten (sammenlignet med simulanter, se mere nedenfor) have fuld, spektakulær farveændring.

SIMULERET ALEXANDRIT
Der er et væld af "simulanter" derude. Hvad vi mener med en "simulant" er en perle, som folk kalder Alex, but it is NOT an Alexandrite stone. Natural or Lab. This is important because simulants either don’t change color or change to the wrong color. Some are even the wrong color to begin with. Most simulated stones are also not nearly as durable. Due to Alex’s mystical lure, simulants have been made since the 1800’s! Så, when looking for an Alexandrite engagement ring, know that just because it’s antique, doesn’t mean it’s real. Always buy from a source that has actually tested and examined the stone.

Is Alexandrite rare?
Ja! Natural gems are exceedingly rare. More rare than diamonds, faktisk. This is because the elements needed to form it do not regularly occur together here on Earth. Som et resultat, der er kun få naturlige Alexandritaflejringer i hele verden! Det betyder også, at der er en reel sandsynlighed for, at disse indskud på et tidspunkt vil være opbrugt. Russiske ædelstene er allerede opbrugt. Med andre ord, der vil sandsynligvis komme et tidspunkt, hvor denne perle ikke er udvundet længere. Som du ville antage, hvilket gør sten af ædelsten af høj kvalitet intenst sjældne. Faktisk, mange guldsmede har aldrig selv set en Natural Alex. Denne spektakulære sjældenhed gør en Alexandrite forlovelsesring til en virkelig en gang-i-livet-gave..
Er en Alexandrite forlovelsesring dyr?
Der er altid en måde at få det, du ønsker, til en pris, du har råd til! Par kan inkludere farveskiftestenen i deres forlovelsesring på flere måder. På grund af dens knaphed, ædelsten kvalitet Natural Alex beordrer høje priser. Så, many couples opt for a smaller Natural center stone or include small Natural side stones in order to make Alexandrite affordable. Another great option is Lab Alexandrite, hvilke, due to being made by man, is much more reasonable.
