Who wants to play "is this a girdle reflection?"

[Goldie987]

I have a similar story to many... I never noticed this line in the side of my diamond until this weekend when I was shopping for a new setting. I never knew what a girdle reflection was before and I'm shocked I never noticed it, if that's what this is. It looks a little different than some pictures I've seen of a girdle reflection, I think because my girdle is unpolished (this is an antique diamond). I don't see any line of any kind from the top, only in the side view. Should I be worried about this? Thanks in advance!

No reason at all to be worried. In my many years as a jeweler, you would be surprised how many of my clients have panicked the first time they saw that line.

Yep, definitely a girdle reflection, nothing to worry about.

Nicely cut prong seats as well.

Its really an ancient frog that got caught up in the stone as it was formed.
We just call it a girdle reflection to keep the club small.
But you have been approved to join the the frog line club!! and learn the truth.
This is our secret dance, we call it the point.
the violin provides the dancin music.

The above is a joke... or is it.......

My sister saw hers and thought she had cracked her diamond. BTW, if a diamond is cut too deep is the girdle reflection more noticable?

No the frog is pretty close to the same with in the logical range for diamond pavilions.
Larger diamonds have bigger frogs.

Girdle reflection is more noticeable with the increase of the girdle thickness.

Great visual and explanation. Thank you.

 

[Goldie987]

Thanks everyone for the reassurance! And the education. I started asking my round brilliant girlfriends if they ever noticed it on theirs and no one has... Just funny we stare at them from the top all day but never even look at the side

 

[WinkHPD]

That is where the sparkle is, so it is good that is where you stare!

I don’t see why a smaller frog couldn’t have been caught in a larger stone.
Did the stones form round the frogs?
Did the frogs have to be oriented certain ways to be preserved this way?

The stone must be cut to match the frog.
That's why weight retention is sometimes only 40%
The diamond forms around the frog.
Stones with no or damaged frogs are cut into different shapes.
Some diamond rough has 2 frogs a larger Queen frog and a smaller male frog galled a Frend.
Melee are almost all Frends so in a 3 stone ring you have the Queen and her 2 Frends.
