Featured I need some help with the stone in this ring please.

This ring is marked 925 & also has a capital "B". It measures to a size 6 3/4 on my ring sizer. The stone is a pale aqua color.

If anyone knows what that "B" means, that would be great, but I really need help with the stone.







Thanks for any & all advice or opinions!!

 

Does it have a cat's-eye effect? Or is that a trick of the lighting? For color it looks more like prehnite to me than any other mineral I can think of. Prehnite can occur as a cat's-eye.

 

Thank you so much!!

I think you have hit the nail on the head. Here is another photo that I believe shows the effect you are referring to in your comment.

 

Word for the day: chatoyancy.

 

Could be a Chrysoberyl Cat's eye or imitation of one. They are usually honey brown but can range to green too. The Honey colored ones are most valuable.
Imitations are more common than real ones. Good quality ones are rare.
Not to be confused with Tiger's eye.

 

Thank you so much!!

I can't be the only one who had to Google this, so I will save you from having to do a copy & paste.

Chatoyancy


Wikipedia
https://en.wikipedia.org › wiki › Chatoyancy

The chatoyant effect is typically characterized by one or more well-defined bands of reflected light, reminiscent of a cat's eye.

 

This is the Chrysoberyl Cats eye I have in my collection. I have several, but this is the best.

 

Here is another pair I have.

 

Chrysoberyl cat's eyeis a gemstone variety of chrysoberyl that exhibits a unique optical phenomenon known as chatoyancy, which creates a narrow band of light that resembles a cat's eye. This effect is most pronounced in the variety known as cymophane, which is translucent and typically yellowish in color. The term "cat's eye" specifically refers to this chatoyant variety of chrysoberyl, where the optical property is so distinct that it is often simply called "cat's eye". The gemstone is prized for its striking appearance and rarity, making it a popular choice in jewelry.

 

Those are very cool @Bdigger!! Thanks for sharing!

 

I have one of those in a stickpin. I think the OP's ring is glass. Glass catseyes come in all colors.

 

Just liked this from the chrysoberyl Wikipedia page: Cyclic trilling of chrysoberyl. Sounds like a mineralogical love song.

 

Another vote for glass, that pale green is one of the classic glass cat's eye colours.
And the setting is wider than the cabochon, which you see a lot with glass cat's eye jewellery because it costs more to fit the cabochon precisely.

 

Gorgeous, Mike.
