sqyong Rough Rock Total Posts: 7 Last Post: 4/27/2009 Member Since: 4/19/2009	Hello, I've narrowed down to 2 diamonds for the proposal ring. I've calculated the HCA too. Can someone help me run a diamcalc/gemadviser to help me "shed some light" into my final decision? Thanks so much! Alex. ====================== ROUND BRILLIANT Measurements: 6.54 - 6.56 x 3.99 mm Carat Weight: 1.04 carat Color Grade: E Clarity Grade: VS2 Cut Grade: Excellent PROPORTIONS: Depth: 60.9% Table: 56% Crown Angle: 34.0° Crown Height: 14.5% Pavilion Angle: 40.8° Pavilion Depth: 43.0% Star length: 55% Lower Half: 80% Girdle: Thin to Medium, Faceted (3.5%) Culet: None FINISH: Polish: Excellent Symmetry: Excellent Fluorescence: None HCA = 0.9 Could see hearts and arrows. ====================== ROUND BRILLIANT Measurements: 6.46 - 6.48 x 3.89 mm Carat Weight: 1.01 carat Color Grade: F Clarity Grade: VS2 Cut Grade: Excellent PROPORTIONS: Depth: 60.1% Table: 61% Crown Angle: 33.5° Crown Height: 13.0% Pavilion Angle: 40.8° Pavilion Depth: 43.0% Star length: 50% Lower Half: 75% Girdle: Medium to Slightly Thick, Faceted (4.0%) Culet: None FINISH: Polish: Excellent Symmetry: Excellent Fluorescence: None HCA = 1.9 Could not see hearts and arrows. ====================== Alex.

Stone-cold11 Ideal Rock Total Posts: 6,900 Last Post: 11/23/2009 Member Since: 9/9/2008	Too big a table to show much fire, probably. Generally prefer a table below 58%.

Lorelei Ideal Rock Total Posts: 34,228 Last Post: 11/23/2009 Member Since: 4/30/2005	Hi Alex, The first is the best choice. The second could be a contender if you like the 60 60 type diamond ( 60% depth, 60% table) - however ASET or Idealscope would be more useful than DiamCalc simulations. So it would be best to ask the vendor if they can supply these images. This tutorial explains the usage and benefits of ASET and Idealscope. http://www.highperformancediamonds.com/index.php?page=education-performance Nothing is more sacred as the bond between horse and rider...no other creature can ever become so emotionally close to a human as a horse.

Second one is a no. Wow... Serious? Why is it so? ======== Alex. Because the first has great numbers all around for a nice mix of fire/brilliance/scintillation. It just falls in a sweet spot. As Lorelei pointed out, the other is cut towards brilliance, less on fire, and possibly some scintillation. Some people like those, there's nothing "wrong" with them per se, but usually those people prefer them for the brilliance, they are not for a lot of people. I would not suggest them for a "first" diamond. ~~~~~~~~~~~~~~~~ "It is also important for the State to inculcate in its subjects an aversion to any 'conspiracy theory of history' for a search for 'conspiracies' means a search for motives and an attribution of responsibility for historical misdeeds." -Murray N.

If I were you, I might take Skippy up on her offer! Unless it absolutely has to be E or F, you have many other choices.

sqyong Rough Rock Total Posts: 7 Last Post: 4/27/2009 Member Since: 4/19/2009	Hello, I've since gave up on the previous 2 and left with this: ROUND BRILLIANT Measurements: 6.49 - 6.50 x 3.92 mm Carat Weight: 1.01 carat Color Grade: F Clarity Grade: VS2 Cut Grade: Excellent PROPORTIONS: Depth: 60.4% Table: 59% Crown Angle: 34.5° Crown Height: 14.0% Pavilion Angle: 41.0° Pavilion Depth: 43.0% Star length: 55% Lower Half: 75% Girdle: Medium, Faceted (3.5%) Culet: None FINISH: Polish: Excellent Symmetry: Excellent Fluorescence: None HCA = 2.2 However, the guy told me their machine measured pavilion angle as 40.8degrees but GIA gave it 41 instead. If It's really 40.8degrees, HCA will be 1.7. And if I use pavilion and crown %, it's HCA = 1.3. What's your view on the GIA grading and what the seller said? ========== Alex.

Lorelei Ideal Rock Total Posts: 34,228 Last Post: 11/23/2009 Member Since: 4/30/2005	The diamond has potential, GIA do round the numbers so I assume the seller ran a Sarin on this diamond? Sarin accuracy can also vary due to many reasons if so. Have you bought it or have just shortlisted it? Does the seller have access to an Idealscope or ASET scope you can use to check out the diamond? This is how I would approach it with this diamond if such tools are available. Also check it out away from the store lights if possible, see if there are any dark areas on the top of the diamond, or a dark ring around the table. If it looks good in all lightings then it could be fine.

No wonder sometimes it's better to know less ;) But on the other hand, this means there is always room for dispute, making our eyes the best tool to make the final decision :) I have actually put down a deposit for it. Wish me luck. I was in a cafe, so no store lights to mislead me. I did use a white LED light to shine on it. Looks good to me. And there was also no dark ring, or visible black dots when viewed from the top. I viewed it against the cafe's window with a 10X loupe, idealscope on an ideal light (quite pink i think), ASET scope (i didn't know how to use this though), and lastly the layman's H&A scope (looks pretty quite).
