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 op die Mohs-hardheidskaal (diamond is a 10)! Met ander woorde, “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. Paartjies moet bewus wees dat natuurlike juwele van 'n laer gehalte meer soos 'n waterverfskildery lyk, met 'n bietjie pers wat oorspoel na die groen, en omgekeerd.

LAB HET ALEXANDRIET VERLOWINGSRINGE GESKEP
Lab-geskepte Alexandrite het dieselfde hardheid, color change, en chemiese samestelling as sy natuurlike naamgenoot. In terme van kleur, 'n Lab-steen se groen tint is geneig om meer blouerig te leun as die Natuurlike weergawe. Sy rooi tint is ook geneig om meer perser te leun. Ware Lab-geskepte klippe (in vergelyking met simulante, sien meer hieronder) vol hê, skouspelagtige kleurverandering.

GESIMULEERDE ALEXANDRIET
Daar is 'n klomp "simulante" daar buite. Wat ons bedoel met 'n "simulant" is 'n juweel wat mense Alex noem, 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! So, 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, eintlik. This is because the elements needed to form it do not regularly occur together here on Earth. As gevolg hiervan, daar is slegs 'n paar natuurlike Alexandriet-afsettings in die hele wêreld! Dit beteken ook dat daar 'n werklike waarskynlikheid is dat hierdie deposito's een of ander tyd uitgeput sal wees. Russiese juwele is reeds uitgeput. Met ander woorde, daar sal waarskynlik 'n tyd kom wanneer hierdie juweel nie meer ontgin word nie. Soos jy sou aanneem, wat edelstene van gehalte uiters skaars maak. In werklikheid, baie juweliers het nog nooit eers 'n Natural Alex gesien nie. Hierdie skouspelagtige rariteit maak 'n Alexandrite verloofring 'n werklik eenmalige geskenk.
Is 'n Alexandrite verloofring duur?
Daar is altyd 'n manier om te kry wat jy wil hê teen 'n prys wat jy kan bekostig! Paartjies kan die kleurveranderingsteen op verskeie maniere in hul verloofring insluit. As gevolg van sy skaarsheid, juweel kwaliteit Natuurlike Alex beveel hoë pryse. So, 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, watter, due to being made by man, is much more reasonable.
