Hello all old cut experts!!! Any info on this stone?

[Rubies-R-Me]

Hello!
I just spent a lovely day with my mother and we were chatting about her engagement ring. I told her how knowledgeable all the people on this board were and that I would be able to tell her more about her stone if I posted pics of it.
A little background.. My parents got engaged in 1954 with this ring. The stone was originally the stone from my grandmother's engagement ring from the 1920s. It's original setting was a very closed up.. one where very little of the stone showed. My mother's father passed away and my grandmother got remarried and got a new ring for her second wedding so the stone was free for my Dad to give to my mother for her ring. Back in those days you could bring a non Tiffany stone into Tiffany to have them set it and that's what they did. It's an old cut stone but I don't know of what type.
Here are 3 pics.. I would love to hear anything about it that you can see from them. She is not a nutsky like me about keeping her jewelry clean so it's not pristine but I think the faceting pattern is still visible.
Thanks in advance!! HAPPY MOTHER'S DAY TO ALL!!!

It looks like a beautiful transitional cut. You should give it a bath though There's also some wear around the girdle, but that's totally expected for a stone that's had such a long history of being loved and worn. Beautiful ring!

I'm n expert I just wanted to say that's a lovely ring and how neat that Tiffany's used to set other peoples stones! They should go back to that (I wish)

It's pretty dirty, but given the patterning and era of origin, I think its an early ideal cut like mine or like Demelza's!

Whoo, that is something to be envied! Rubies, what a great history behind the stone and ring. Would you be the lucky owner of it one day (hopefully) far down the road?

Hi!
Thanks everyone who chimed in on my mother's stone.. I am going to look up the two types of cuts mentioned.. transitional and early ideal and read more about them.
I am also going to bring my jar of homemade jewelry cleaner to my mother's house this Sunday and clean that baby up! It won't stay clean for long though.. my mother is the type who puts on hand lotion with her ring on.. I barely will sneeze with mine on.
My favorite jewelry cleaner is very unsophisticated but works well.
Buy a jar of canned fruit that comes in a plastic jar or a jar of applesauce.. eat the fruit or applesauce (too bad it's not hot fudge!) and then fill the jar with 1/3 sudsy yellow ammonia or any type ammonia and 2/3 water. Then put in a extra soft baby tooth brush into the jar.. it should be short enough to be able to screw the lid on with the brush in it. When you clean your jewels pour an inch out into a small glass dish and then soak your pieces in it for a few minutes. Then use your tooth brush to gently clean each piece then rinse. Pour the liquid back into the jar for next time.. it can be used over and over. I just noticed that mine needs some replenishing. That's my claim to fame.. home made jewelry cleaner.
It's also fun to give one to somebody who just got engaged. You can decorate the front with a small index card with "******s Jewel's" and a drawing of a ring and then laminate it on with clear thick packing tape so it doesn't get wet.
Arts and crafts is over for today!
