The mineral
A stone we choose loose, in daylight, one at a time.
In the hand
At 8.5 / 10 on the Mohs scale it is heirloom-hard: wear it every day for a lifetime and let the metal show the years instead.
Treatment, plainly
Grown above ground with the same chemistry as its mined counterpart. The passport says lab-grown in those words, and the price says it too.
Choosing one
Photographs flatter and light booths lie. We choose lab-grown alexandrite in north daylight, loose, against ivory paper, and we would rather show you two honest stones than twenty pretty pictures. Teal by day, garnet red by lamp, grown in a lab and disclosed.
Care
Warm water, a drop of dish soap, a soft brush. Store it in its own pouch; it will scratch softer stones sooner than they scratch it.
