A synthetic Alexandrite gemstone created using the hydrothermal growth method.

the gem displays a colour-change effect from reddish-blue in daylight (images 1 to 3) to an intense red in incandescent light (image 4).
When exposed to UV illumination, the stone displays a distinct pinkish-red fluorescence (image 5).

Under magnification, parallel growth lines are visible, displaying zones of colour distribution (images 6 to 8).

Not to be confused with the far more common Alexandrite-like synthetic Sapphires produced by the relatively inexpensive flux-fusion, or Verneuil method, these flux-grown gems were created in Russia in the 1970's and early 1980's and are true synthetic beryllium aluminum oxide colour-change Alexandrites with both physical and optical properties that match the natural counterpart.

A rare man-made gemstone for the connoisseur.
