My husband and I looked at so many ovals before we found the right one. Have you tried on any in person? Even if you ultimately buy online, you should see what l/w ratio you like, etc. In my personal experience, you have to see it in person to evaluate the bow tie effect despite all the charts and numbers that are out there to help predict how the cut will impact that. Good luck!

diamondtobe :  I would rule that one out as I see a bit of half moon activity on the tips.  People talk about bowtie but I don’t hear enough talk about the half moon dead ends that ovals sometimes have.  Are you set on James Allen?  They don’t tell you the depth percentage of the diamond or let you see the certificate without specifically requesting it one diamond at a time.  I can get around the depth percentage problem for the most part by setting the advanced settings up do depth percentage is restricted to 59-61%.  But I prefer diamond hunting on brilliant Earth’s site.  Also, are you open to a lab diamond?  You could get more diamond and great specs for half the cost.

I purchased a ring from Brilliant Earth as an experiment a month ago.  Mainly to see if I was on the right track with my diamond searches.  I knew I would probably return it so I wasn’t worried about the setting being perfect.  The setting DID turn out perfect but after buying it our water storage tank died, $1000, my son broke his arm (again) launching more detailed tests and catscan ($$$$) and our car needs repairs.  It’s too ridiculous.  So the ring is definitely going back in the next couple days.  But.. the diamond is amazing, making me feel more confident about purchasing online with careful scrutiny.  Specs only take you so far, but depth percentage and “excellent” symmetry are the most important with ovals.  Then use your eyes to look for bowtie and rule out half moons.  I’ll attach a pic.  This diamond is a G SI1.  Polish and symmetry excellent. Depth percentage 61.3%.  I will not go higher than 61.5%.  length to width ratio 1.39.  0.75 carats on size 4 band.  Total cost for diamond, setting and taxes, $2500.00.  I am in love with lab diamonds.  Did I mention it’s a lab diamond?.  Cost would have been close to 5k with mined diamond.  Here’s pic set in 18 kt gold.

diamondtobe :  lol.  I gave info for comparison purposes.  Let there be no confusion.  I’m not trying to sell this ring via any forums 😂. I already have the free return label. I’m sending it back for a full refund.

diamondtobe :  I’m sad that I couldn’t get a pic without my phone blocking the light to the stone.  It not as lit up in the pic as it is in real life.  I almost never see any hint of bowtie which surprises me.  I have an E VVS1 .7 pear that has typical bowtie action.  But I made the mistake of going with “very good” symmetry and ordering it blind bc it was a last minute swap at the jeweler’s.  The bowtie is a little more pronounced on one side of the stone and I always notice even if no one else does. :/ I’ve never been fully happy with it and I have realized the importance of symmetry and depth percentage because of it.  My pear is.  62.5% depth and that is too deep for stones with bowtie.  I stick as close to 60% now as I can.

Is there a reason for high color and clarity? Since this is a D with strong flou the diamond may appear bluish in the daylight, I would also test it in all lighting situations to make sure there isn’t any haziness (rare but it can happen)

 

personally I like this facuet pattern for ovals but again it’s a personal preference

 Yeah.  I agree with kkjohnson.  The strong florescence is an issue.  It’s been so long since I even looked at florescence ratings since I’ve only been scoping lab diamonds and they don’t have florescence.  But the pear I own has faint florescence.  Most florescence is blue but mine lights up violet.  And it’s noticeable.  I don’t mind.  But unless you would enjoy your stone fully lighting up to whatever shade of florescence it emits when it’s in sunlight, don’t go with strong florescence.  I’m a bit so I might do it for fun, deliberately.  But it’s not for everyone.  And with strong florescence there is a risk of the diamond looking milky.  Be careful.  Go down to a G or H and clarity of VS1-SI1 to get the cost down.  I know clarity was an issue with your last diamond, so I wouldn’t do an SI2.  I rarely can get on board with an SI1.

The best thing you can do is ask to see the GIA certificate. The website says you have to request it but it is at no charge to you and you have every right to do so. 

my certificate (it’s a lab diamond so it’s a GCAL certificate) shows the light performance. Notice how there is no darkness in the spot a bow tie typically appears. This is very true in person and my oval has ZERO bow tie which is insane!! Some full proof advice for ya 😌

Oh and it’s SUPER shiny!!!!!! It catches people’s attention all the time because it’s so shiny 😂 This info definitely was spot on with brilliance!

Can you get an ASET? That would be my next move. An ASET is used to determine light performance.

I would not go with the diamond you posted in your original post.  The diamond kkjohnson posted looks good.  It’s not the usual cut and will have a very “crushed ice” look.  Ovals already do at each end where the bowtie isn’t going on, so technically they are crushed ice stones. 

Here’s another you might like:

Sunburn is right about the ASET.  It’s the best way to know about light performance.  It’s just that with James Allen this is getting so tedious, especially since you can’t even see the certificate without specially requesting it.  Do you have to go through James Allen because you’re locked into an exchange program with them and getting a refund for your first stone is not an option?  It would be helpful to know that.
