Thanks Lisa I am glad that there is someone that can confirm that Alexandrites that turn RED do actually exist and I am pleased to see that you have one like that .
Anonymous , this was a very old post and I explained that I hadn't had the chance to do it then. actually I hadn't been on this website for almost a year because I was actually extremely busy .And I got rid of it and so on to make an important purchase but this is not why I opened this threath. .
Chrono actually the better quality Russian ones are actually expected to have a chery red color which was the color that I was trying to describe so I know how to recognize a cherry red/deep red garnet color when I see it .You can even see it a little bit on the video even if it looks more intense in person.
Here is an inetresting text that I just found
Alexandrite is considered a transparent gem which appears green in the daylight and red to purplish red in artificial light (indoors) . This phenomenon is known as color-change. Alexandrite is strongly trichroic (phenomenon of different colors appearing when viewed from 3 different directions)There are variables which affect the price of this gem including how dramatic the color change is, modifying colors, size, and location Alexandrites are found. When the color change is dramatic, the stone will be very expensive. Less expensive stones will have a weaker change and less saturated colors. The color phenomenon is a result of the presence of chromium ions and the way those ions are absorbed and reflected. The presence of brown or gray modifying colors will lower the value vs. the price per carat on alexandrites with the lack of these modifying colors. Alexandrite is more common in smaller sizes but still fetch a steep price tag due to the rarity of the gemstone and the current command in the market. Price on fine smaller stones range up to $10,000 per carat.There are large alexandrites which are very clean, but generally most stones have many inclusions including negative crystals & rutile silk. Ovals & cushion cut stones are the more common cut styles seen in the market. Alexandrite was originally discovered in Russia in the early 1830’s & this is where the finer top quality gem stones are found and command a premium. Russian stones are described as displaying color change from very green to dark cherry red. Some other sources of alexandrite include Ceylon & Brazil. Alexandrite is part of the chrysoberyl family. Some imitations or fakes include natural color change garnets & synthetic color change sapphires.
Chris I do not watch JTV because all they sell is industrial diamonds and their cheap quartz among other things as if it was something from De Beers.If you have Time warner cable you could check channel 270 .It is more medium to high end but very pricey .
Oh I didn't know that Diamonds were single refractive ...That is something I learned today.
LD your comments sounded pretty accusatory and downright nosy . I know the difference between someone that is honest and someone that just means harm .I have my reports and I am keeping them in a safe ( in my bank ) along with some of the other valuables so I am really not looking for any arguments here . Yes they costed just under 100$ (I never said otherwise) because it turned out the person that sold them didn't know their value but when I sent them to the AGL ( because the color change was just too outstanding ) they were confirmed to be Russian .And just because Russian mines were depleted does not mean that all the Russian alexandrites that were produced disintegrated into thin air .I know there are lots of dishonest sellers out there but the person that sold them to me never said that they came from Russia in the first place. She didn't know the origin of it.
To wrap this up the purpose for posting this thread was also to let you know that Tan does have some wonderful gemstones for great prices if you are interested .That was just my way of thanking him .I actually have a link to a 4 carater

There is an element of brown in it but the size and the color change are very good for the price just in case anyone is interested.
