When I went to look at rings with my SO, the jeweler brought out different color/clarity options (all of their cuts were excellent/ideal). For the pricing, I decided color was way more important to me than size, and all of their diamonds were eye-clean, so I opted for a smaller diamond but with D color and SI2. I was super color sensitive, but it was funny because i could hardly tell anything about the clarity so I could drop to as low as eye-clean SI2 and I would never be able to tell. Hope that helps! I don’t have my diamond yet (fingers crossed it’s this week, but who knows), but i’ll post when I do know! 

SN – especially when going up to a diamond as large as 2 ct, I think you might be able to see flaws/imperfections more so than the diamonds I was looking at (.5 – 1), so keep that as a side note for yourself for clarity. It always helps if you can see it in person.

Hi msc08,

Full disclosure: I’m a man who loves diamonds and moissanite and gems! I spent many many hours learning about diamonds at Pricescope and other websites before I purchased a diamond. It’s very smart of you to make cut the number one consideration as a well cut diamond will perform the best and face up nice and white. My stone is an I and it’s in a tension setting so I do see it’s slight tint from the side. I would take a lower color for a larger size but I personally wouldn’t go lower than an I. If I could do it all over again I would buy a precision cut diamond such as those sold by Brian Gavin Diamonds, Crafted by Infinity or A Cut Above. That will take all the worry out of getting one of the best cut stones.

If you’d rather try to pick a winner on your own…Here are some cliff notes I saved from Pricescope written by John Pollard for staying near Tolkowsky/ideal angles with GIA reports (their numbers are rounded) 

A crown angle of 34.0, 34.5 or 35.0 is usually safe with a 40.8 pavilion angle.
If pavilion angle = 40.6 lean toward a 34.5-35.0 crown.
If pavilion angle = 41 lean toward a 34.0-34.5 crown.

Here’s a photo of my VVS1, I, diamond.

When buying a diamond, cut is king.  That’s what gives it fire and brilliance and can cover minor inclusions and lower color grades.  I told my Fiance that cut was most important to me followed by carat.  So basically to get the biggest, best cut he could afford lol.  My diamond is set in rose gold so he was able to go down to an I colored diamond, and it is an eye clean SI1.  Because it’s a hearts and arrows cut round brilliant it looks perfectly white most of the time, but I do see the warmth in certain lighting.  The sparkle never disappoints though!!From the choices you gave I think it would depend on what you are planning on setting the stone in.  If it is being set in white gold or platinum I would prefer the 1.7 to 1.9 choice.  If it is being set in rose gold or yellow gold I would choose the 2 or 2.2!

We just upgraded from a 1.08 to a 1.90 ct. I could not see the difference between 1.9 and 2 carats, it’s literally the same. However, I could see color in below a G even at the 1 carat size. both of my diamonds were G SI1, and completely eye clean. Look at pricescope to research as well as use the HCA tool to determine the ideal cut. Ours were both amazing performers HCA under 2, GIA triple EX. Cut is king! Staying slightly under 2 CTs saved us like 2k since I did not want to lower color. When I looked at I color I could see the tint.

So long as the clarity you choose is eye clean you should be good to trust the cut if you’re going with ideal cut, ex symmetry and polish. If the diamond is well-cut it can help a little with the appearance of the color. Going to a 2 ct or above makes it more difficult to find an eye clean stone and drastically increases the price, so staying a little below the 2 ct mark and considering some fluorescence may make a difference if you choose to have a warmer stone. H-I would be an amazing choice with the right cut and setting which would save some money while still giving you the look you’re going for…

To go a little beyond what the GIA told me, I used the HCA tool as a guide and the following additional guidelines:

table percentage: 55-57%, no more than 58

total depth: 60-61.5%, no more than 62

crown height: 14-16%

pavillion depth: 42.4%-43.5%

girdle: 2.5-3.5% (mine is medium to slightly thick) if the girdle is too thick you can have light leakage and less sparkle 

My stone is G, triple ex, VS2, G with faint fluorescence, 2.03 – I was open to any stone that performed well and this was the best option in my upgrade scenario with Ritani.

msc08 :  I’ve heard of them but I didn’t know they had a storefront. Or did you go to an authorized dealer? Either way, did you find any different options you’re considering?

msc08 :  Honestly, a diamond can look great on paper but the proof is in the pudding – if this new diamond is in your price range and you think it sparkles it’s hiney off, go for it! The awesome thing about diamonds is that they can come in many cuts, clarity, colors, etc. but each stone performs differently.
