If you have a 25 ct. stone than it is not an alexandrite but a synthetic corundum. The quality of synthetic corundum doesn't matter since it really has next to no value.

Alexandrites are extremely expensive and would not be put in a 10k ring. However I can't tell you what you do have because I don't have the stone in front of me. To do a proper analysis of a gemstone I need to be able to actually see the stone and take a variety of tests on it. No legitimate gemologist would guess at what you have from a vague verbal description of the color. If you are in my area you are welcome to come in and I can look at it. If you're not you can take it to any AGS (American Gem Society) jeweler in your area and their gemologist can tell you.

The stone is lavendar in some lighting and bluish/lavendar in other lighting. If I look through the center of the stone toward the light (there's an open spot in the setting), the stone is yellowish. It also tends to pick up coloring from its surroundings sometimes.

Most likely, in that size range, you have a synthetic sapphire unless your grandmother was dating a very wealthy gent at the time who gave her the stone. I am happy however to look at it anytime and tell you what it is.

My mother was thrilled! I am now in possession of it, and have been researching all about the elusive Alexandrite. I am afraid of shipping it off, so will arrange for an in-lab visit. What I would like to know is, would something that I can at least date to the 40's/50's with a blue-green to purple-pink color change be a synthetic? Based on what I have found, it is about 2.2 carats.

However what I can tell you is that under both long and short wave ultraviolet light alexandrite will fluoresce a weak red color. Some synthetic sapphires fluoresce a yellowish color under ultraviolet light so it is possible that you have a synthetic corundum (as I discussed in the article). If the stone is substantial in size that is probably what it is however I suggest you to take the stone to a gemologist for confirmation on what it is.Daniel Spirerhttps://www.blogger.com/profile/14032480090757085386noreply@blogger.comtag:blogger.com,1999:blog-5590775563993110893.post-52244854690226750732010-09-09T18:04:25.551-04:002010-09-09T18:04:25.551-04:00Hi

Very informative and cleared up a lot of questions I had.<br /><br />Thought of one more, though not as directly relevant to your business, as you don't sell silver items. Curious if you have any comments on polishing silver jewelry and/or keeping it untarnished in the first place. I believe it's supposed to be best to keep silver items in silver cloth as polishing essentially damages them; but I have some that have gotten tarnished and dread the thought of sitting down and trying to polish all their tiny little crevices. Any advice on getting and keeping them shiny?Laurelhttps://www.blogger.com/profile/13440658754416289147noreply@blogger.com
