Question on my oval diamond tilt window

[Diamond_14]

Hi everyone. I recently got this diamond set and I’m wondering if this behavior of what I think is a tilt window is normal for ovals. Once the diamond is tilted beyond a certain point you can see through it. You can see it at the north end of the stone it becomes dark.

I’m hoping this isn’t too bad. :/

I really like the stone so I am wondering if maybe this is fairly normal for ovals and would be difficult to avoid.

thanks all.

Completely normal and unavoidable.

@distracts Thank you so much for your reply. I’m such a newbie on this stuff and have seen so very few diamonds in person so I really appreciate the knowledge of the community. I appreciate your help putting my mind at ease on this.

@distracts do you know if that happens for other diamond shapes as well? I’m just curious about it and cannot find much information online. Thanks.

Hmm... glad this post came up. I'm trialing a loose oval now and just tried it and seeing the same. Because it is a loose stone, it happens no matter the orientation on my stone. So, if I rotate the stone clockwise and tilt, the same thing occurs and so forth.

I'm also wondering if it is a function of the traditional oval or not and if getting a branded oval may eliminate this?

It happens for most shapes. Some more than others. If you go to a website like Blue Nile or James Allen where they have the rotating 360 degree diamond videos, you can check out a bunch and see it.

If you look at something like the Elyque ovals, and watch the videos, you can see it happens with them as well:

It's a function of the way faceting works. Perhaps you *can* engineer a diamond to have good performance from all angles, but the closest I've ever seen to that is an Octavia asscher. Ideal cut rounds come pretty close, and in chunkier cuts like old cuts the tilt window isn't necessarily as noticeable. But in a lot of the cuts with smaller facets, tilt windows stand out a lot because of the contrast with the smaller facets you see when the diamond is face-up.

Ahhh, you're right. Just looked at the video. Hmm.... older cuts, you say? Leads me back to the antique ovals.
One cut I have absolutely fallen in love with is the Sirius Star Oval. It was recommended here in an older thread I read, and OMG . It's by master cutter @MikeBotha . I love the facet pattern the best out of the branded ovals I've seen.
Not sure if it that cut is considered antique or modern, but it's divine. Only thing is that it appears to be very limited in the US. I think I may wait it out though!

@CaprineSun would you be willing to share a video of your oval doing the same thing as mine? I am curious to see. Also those Sirius Star cuts do look stunning!

@distracts I think I see what you mean in the videos. The diamond sort of grays out like the background color like in the left side of the photo below. I appreciate the discussion on this, it has helped me understand this is common and to NOT feel that I made a "horrible" mistake in picking my diamond.

I couldn’t get a good video but managed to snap a pic showing it.

First pic is in the spring clasp diamond holder ring (that has already oxidized in less than a week lol)

Thanks so much for sharing, it looks like a beautiful oval

My need to know more got the best of me today and I went to a store to see some more ovals in person. It seemed liked they all had this effect and it is indeed just part of the cut.

I showed my boyfriend the tilt window and how you can see the skin color through the diamond when tilted and he still really loves the stone we picked out so I think it’s a keeper for us. I feel better after talking to him about it. I played a really big part in picking the stone so I felt I had failed in some way when I noticed this tilt angle because I felt it made the stone not “perfect” anymore. I didn’t notice it until it was set in the ring. However, he reminded me that beauty is often in these little nuances of things and what the ring will stand for. I still really want an oval so I will accept this tilt window as part of owning an oval diamond

Thanks all for the discussion and help on this. Please feel free to chime in with anything else anytime!

It's pretty common for people who aren't familiar with diamonds to find some aspect of it they weren't expecting and worry they made a bad choice. But a lot of the time it's just something that's normal that they hadn't seen enough diamonds to know about! Deciding to see more in person was a good move.

Your oval looks great. You did a good job picking it!

@distracts Thank you so much for your help, expertise, and kind words. I really appreciate it. I think you are exactly right and that it is definitely the case here where I simply had not seen enough diamonds to notice this particular feature. In fact, I think my oval is only the second oval I saw in person with the first being one I saw very briefly at a jewelry store. Alarms just sounded in my head when I noticed i could see through my stone to my skin at certain tilt angles. I think it was alarming to me since it is such a big and important purchase and I am new to diamonds. I am grateful you were here to tell me that it’s normal. Now when I see it I won’t see a problem, but rather just another part of the stone’s cut.

Oh also for people who are interested, I thought this video shows the tilt window pretty well. It appears white in the video due to the background but you can see it when the diamonds are tilted, particularly in the ovals.

thanks all.

All diamonds have a critical angle (just like all mediums I believe)..., in laymen term this means that whenever looking through the table of a diamond, the opposing (usually pavilion) facets must be positioned at a minimum angle slope (relative to table) in order to return light reflection..., below that minimum angle the diamond appears see-through..

It happens in every diamond cut and design..., obviously the more out of square/round ratio, the more noticeable/visible as elongated shapes require shallower facet angles on the lengthy sides of the shapes.

Some designers or planners take this fact more into consideration and are able to minimize this phenomena.., but is short, every diamond shows leakage in certain viewing positions..., part of reality. The secret is to be able to balance such leakage spots relative to the active facets.

Hope this explains it better...

Thanks Garry..., and I am breaking my mouth trying to explain as simply as I could

 

[diagem]

Very interesting position as I look closer...

Notice how "just" the 2 left (individual) light rays hit the upper crown facet section of the diamond which receive a steeper angle relativity are the only rays that continue their travels in the diamond material!

A perfect demonstration Garry..., thank you for adding this.

Adding my touches (hope you dont mind...)!
