What’s going on with this transitional?

[nala]

I think it’s a transitional stone. In the best lighting I can almost see a checkered contrast but I can’t catch it in my pics! Calling the experts.

Don't know about checkerboard but I'm loving whatever it is doing. The petals under the table are fat and it's got lovely contrasts.

I would describe it as an OEC, but I see what you are talking about. Also see some fish eye. Perhaps it was an OEC and got rehabbed so the top facets are more organized and tranny in appearance, and the bottom is more OEC? Can you get a profile shot to show crown height and table size?

Welp, I'm certainly no expert
Looks like a flower petal-y OEC to me.
A lot like the modern Canera designed

Huh, so it’s kind of strange how the petals in the center on the top are rather well defined but then they get almost a watered down look towards the bottom.

Overall it’s a really pretty ring, does it have good performance despite the pictures? It could be just camera shy but lovely otherwise.

@ItsMainelyYou is right on the type of faceting. Mains are wide and under-table is nearly filled by pavilion mains. Very little lower half visible (orange triangles are visible lower halves).

Table looks larger than it is proportionally thanks to the bezel covering a portion of the edge…

The paddling is characteristic of shallower pavilion (without steeper crown to offset). Green arrows.

This is supported by the small table reflection… Which is usually round, but that’s because modern rounds have better optical symmetry. Light blue outline.


The culet looks to be off-center. This means that the mains on the side where culet is closer to girdle are slightly steeper than the mains on the side where culet is further from the girdle.

All the mains are reflecting what’s currently in front of them. For some of those facets, like skinny purple arrow, that’s obstruction from a dark (or darkly shadowed) camera. For others, like thick purple arrow, it appears that that’s you…

Wow @yssie! Thank you so much for your thorough analysis! I would be lying if I said that I could fully understand how each component affects the overall image that I see, lol. But I’m gonna keep studying your analysis.

I swear that I saw checkerboard but yes, then I saw the petals!

She came home with me! She’s .50 center and a lot worn out bc she is a true antique! But she’s a lot of fun!

 

[nala]

Ok. Here is what I thought was checkerboard! Haha.

 

[YadaYadaYada]

Oh excellent! Like I said before, whatever the story is with the center diamond, it’s a really pretty ring. Glad you got it!

 

[stracci2000]

I love this.....the profile is wonderful!

 

[yssie]

Takehome is probably that the checkerboard pattern in a typical transitional is created by the alternation of wide-but-not-OEC-level-wide mains that are shallow enough to obstruct, and steeper lower half facets that are “leaking” and a table large enough to show a lot of the lower halves… In this stone there’s hardly any lower half visible - the under-table is all mains, very wide, and the “almost checkerboard” you see is created by shallow and even shallower mains reflecting the dark and light stuff that’s right above them

I have a stone that does the same. Sometimes I see checkerboard, sometimes I see petals. So interesting to hear what may cause this.

Gorgeous! We are lucky to have experts on ps!

 

[nala]

Ok. Here’s a pic of what I see in some lighting!

One more close up

Hiya @nala ! I couldn't find this the other day but just for fun...this is what I would call a typical transitional with a medium culet, if you're wondering.
