Such a personal preference really! I love OEC’s but I have seen some beautiful RB’s I wouldn’t turn down. I think you need to see both in person.

missbeekay:  I think they both sparkle under different lights/conditions. I was recently on a flight and my OEC moissy threw off so much sparkle on the seat in front of me. It was a total rainbow show! And it will differ between diamonds (good cut vs poor) and other stones.

missbeekay:  What stone? Moissanite is always going to be more blinding than a diamond regardless of cut, that’s just what it does. RB sparkles more than OEC because it has more facets. My ring has an OEC diamond and it sparkles beautifully. There’s really no wrong way to go.

The oec has more bold chunky pastel flashes and the rb has more splinter like dico ball sparkle. Overall I’d say the rb is probably more sparkly but I prefer oec’s.

I have a couple youtube videos of the oec I used to have. I can’t copy and paste the link for some reason but it’s under ” forever brilliant OEC moissanite sparkle”.

missbeekay:  definitely OEC’s exhibit much warmer, pastel-y, chunkier facets, which can be memorizing yet quiet. Whereas I think a well cut RB can give wall to wall whiteness and ‘in your face’ sparkle. JMHO

My mother has a 3.5 carat OEC or old mine cut, whatever they were called in those days, with the small table, and facets made for sparkling in candlelight, and it is breathtaking and I want it so bad!  It’s amazingly beautiful and sparkly, you just don’t see stones like that anymore, it was my father’s grandmother’s.  However, as far as blinding ability goes in sunlight I have to say, my two carat round brilliant really hurts my eyes sometimes!  And I think that’s what it was made for.  I truly love both.

I think the RB is sparklier because it has more facets than OEC.

Round brilliant is cut to return the most light. A RB will almost always outshine an OEC. That doesn’t necessarily mean a RB is more beautiful, as that is a matter of opinion. Just like a RB will out-sparkle an emerald cut, too, but I doubt most owners of emerald cut stones would trade them for a RB.

The RB has more splinter-y white flashes, the OEC has more of a chunky pastel flash.  I love both, but I’m more partial to OECs for the glass look.  When they’re not in light, and you’re looking straight down on one, it looks like a beautiful chunk of glass (Sorry my brain is functioning at half capacity and I can’t think of a better way to say it).

I do like H&A cuts of RBs, as they have a more distinguishable pattern when viewing from the top without light.  It really just depends.  Do you like the soft, warm pastel-y glow of an OEC…or the chiseled hard, bright white flash, and defined pattern of RB?

If it was up to me, I wold take a big ol clunker OEC anyday.  But if I couldn’t have that, I would take a high quality RB with hearts & arrows over a regular good cut RB (I dont care for the crushed ice look bUT ive seen some really nice ones).  And nothing looks good if it’s cloudy or too strong fluorescence…every pic in the sun will show as a bright white Rock with little distinguishable pattern.  Your best bet is to watch videos, and view in person.  Every diamond is different.

I prefer OECs, but admit RBs…and here I am referring to excellent/ideal cut – are more “blinding”. OEC’s have chunkier flashes due to their cut, but aren’t exactly cut for optimal light return. Even the “best cut” ones will have leakage by their very nature. I think whether or not you like an OEC is more about whether you are drawn to that pattern or not (and each OEC can have a different pattern). RB’s are ideally cut for optimal fire and performance, minimal leakage and therefore end up being flashier. They just have better scintillation. Of course, there are also some poorly cut RB’s, or which can have certain flaws, that impact performance.

One other thing to note is that OEC’s should have an open culet, which can lead to a kozibe effect at certain angles; this is generally a love it or hate it thing. OEC’s also are deeper, have small tables, etc, all of which can be something you either like or don’t like.

I don’t know, I think of OECs as slower, and more subtle in their performance. I love it, but if you are looking for high flash, an RB is a better bet.

This is my first moissanite OEC in shaded sunlight, I now have a different moissanite OEC, but this photo shows a few unique things about OECs. This particular stone had a medium-large culet, and you can see the kozibe effect here. Because of the larger facets, it also tends to “throw” and reflect surrounding colours a lot more, and you get those chunky pastel flashes (an RB tends to throw more white/glittery flashes). While this is a moissanite, OEC diamonds also share the characteristics of chunky, pastel flashes, open culets and kozibe effects. If you go to the Jewels by Grace website, and look at their vintage rings, they have many diamond OECs, photos and videos, and you can see this.

(I later replaced with an Amora Moissanite, which has a slightly smaller culet but still gives the kozibe effect).

They really are entirely different cuts, and I think some people are just drawn to one over the other. Much like some love step cuts and some don’t.

missbeekay:   I would say they are different.  The OEC will reflect far more light and sparkle more in low light conditions – indoors, for example.  The facets are larger, and they were designed and cut for candlelight.   The RB cut has more facets, and is very sparkly out of doors and in sunlight.  

I have an OEC and I am amazed how many people notice it, and remark on how it sparkles.
