You need to go by mm size, not diamond weight if you are looking to compare visual size. If you are assuming excellent cut, then yes, you will see a difference, althugh slight. A one mm difference is a big difference in the visual look of a stone. I am not saying .1 ct = 1 mm, but I am saying that you need to compare the two stones and compare the mm of each stone. The face of th stone is the mm across the top of a round brilliant (they actually give you two measurments for a round – top to bottomm and side to side. They should be relatively close (within .o5m).

I would pay extra for an extra 10pts if I’m considering smaller than half a carat diamonds or if I’m targeting a hidden message, like a groom wanting a 0.94ct princess because his bride was born in 1994.

I would also pay extra for extra clarity until I get up to the Vs.

Just my $0.02.

Happy shopping, Bee!

 

 

eta: This reminds me of the great moral equivalency debate about speeding tickets. I hear so many people say, sure, you can go ten miles above the speed limit and not deserve a ticket; that’s a normal speed! Well, on the highway at 70mph posted speeds, ten above is only 15% above the limit. In the residential zones with 25mph posted speeds, ten above is 40% above the limit. Big difference. People like to focus on the raw number. Ten miles above is only ten miles above, right? Pfft. [end rant]

geembee:  Hi! Just wanted to say, my 1 ct SI2 diamond is a K color and honestly, it looks perfect to me. I don’t notice any yellow coloring (It has a melee diamond halo in white hold). The cut is also so great (ideal cut), that I don’t notice any inclusions. I would say it’s definitely important to see your diamond in person for this reason. Before we picked out a diamond, I thought I needed a “better” sounding diamond, but after seeing it, I realized that wasn’t true!

@geembee: Also, we didn’t even have the diamond details when we picked out our diamond. We just had a really great jeweler (friend’s father actually!) who showed us a few different diamonds in the size we wanted and we just picked the one we liked the best. 🙂

geembee:  I’m assuming you aren’t getting a step cut if the jewler is saying you can’t tell the difference above S1?

A step cut is the really see-through “blocky” cuts, like emerald cut or asscher. They show all kinds of inclusions so I’d definitely pay extra $ for extra clarity on those, well into the Vs, actually, so I should’ve mentioned that in my earlier post. Good point, LilliV.

geembee:  I looked at finger coverage comparisons and this .9 in size 6 has almost the exact coverage as a .75 on your 4.25. Around 39% for us both.

geembee:  yep! That is exactly what I mean. There is a .1 difference between the diamonds on each side. Both diamonds got billed as a rounded value (we bought vintage from a jeweler) and like everyone else is saying there is some leeway with saying “one carat” or “half carat”. One thing you can try is popping into another store and saying you want a carat. I will bet you they actual weight of some of those rings will be 0.75. We only see what the face of a stone is in a ring. The only way I can tell which diamond is bigger is by flipping the ring over and seeing which diamond has longer point. They face up exactly the same. I only found out the size difference when I went to get an independent appraisal for insurance.

geembee:  I’m also going to add that one diamond is M colored and the other is J colored. I actually can’t tell and the appraiser had to whip his master grading set and take the gem out of the setting before he could. If you’d like to get an upgrade on size and you are getting a round brilliant, you can defiantly take a hit on color. The light in jewelery stores is weird. Try to get a look in natural light because you probably can’t see a difference without a loupe and bright lights. Since I insisted on vintage we didn’t have much choice on the 4c’s. Vintage was my way of buying “ethical” as all the materials were recycled and we were able to get my dream ring (the sapphire is a natural color changer, it is violet without the camera flash).

I have a .35 SI1 excellent cut stone of E colour, in an airline halo. I actually like it a lot better than the .75 solitaires I was trying on.  It also happened to be priced like a g-h colour ring, because as PP said, they stick rings into price bands and this one happened to have one characteristic much higher than the rest. I can see one inclusion from the side/bottom if I twist it right (it’s a crystal, which means it’s a tiny stone within a stone! Two diamonds, one setting!) but it doesn’t really affect anything else. Personally I would go with the .75 and take that $500-700 to pay for a huge chunk (if not all of) the wedding band.
