The good news is that yes, you can replace it fairly easily, and at a reasonable price. There is very fine Amethyst from multiple sources available on the market these day, South America, and Africa both produce a lot of this material. Actual price will depend on size. |

Another upside is that 'siberian' is generally a color descriptor. I think it is unclear if Siberia was ever a real producer of fine amethyst (it's a huge area so there's no doubt that there's some amethyst in there, but just in terms of major production). A fine African stone will give you all the red and blue tones you want, depending on orientation and lighting conditions. |

Also note, that the stone in the picture is nowhere near what I would call "Siberian Color". It looks like nice Brazilian to me, but not top color for Amethyst. |

Not what I would term Siberian. Looks Brazilian to me too. The 1940's is also telling. During WWII our military was exploring Brazil to find deposits which may have aided them during the war. Like copper, nickel, molybdenum, berylium, silver, titanium.... Many important gem deposits were stumbled on at the same time resulting in the export of very large examples of topaz, amethyst, aquamarine, citrine, smoky quartz etc. when the war ended. We saw these mega gems come into fashion in the late 40s. It is my understanding that fabulous deep bluish amethyst with red flash was indeed deposited and mined outside of the town of Mursinsk near the city of Ekaterinburg (I was there a few years back ) from the mid 1700s. "Siberian amethyst" is now primarily a quality designation although one does find actual Ural material in antique Georgian and Victorian jewelry......occasionally. Late Victorian amethyst and demantoid lavalier |
