Also, please feel free to give any advise on buying emerald cut diamonds (i.e. cut, color vs. clarity, etc.)

odds are the si1 wont be eyeclean very few of them are.

Frankly this might be a decent classic EC with those numbers kinda glassy and such but Id look for a smaller table myself with a high crown.

H or better vs2 or better table in the high 50s to mid 60s, get lots and lots of pictures and or a video if not seeing it in person. Crown height 10% min.

l/w is a personal issue but the very long skinny ones aren''t very good performers in general.

In general Storm this is all true.
But as long as the keel length = L-W these 1.5 LxW ratios can work.
Also I often see SI1''s (maybe 1/4 of them) that look fine in EC.

H is getting low in colour for a 1ct EC

But Reglyn we can not tell without images - especialy ASET or GemAdviser images

1.5 l/w cut right is OK.. agree.. 1.6 maybe and definitely 1.7 not...Where would you put the cut off?
I view si the same way I do in asschers if you find one that''s eyeclean too you in person kewl but they are risky when going after virtual stones.

H color, the ones Iv seen were OK at 1ct. if they were well cut. I/J will usually show some tint that might or might not bother some people.

I made the same comment about SI2 clarity in someones 4 or 5ct round search recently and got howled down by 2 women who had eye clean stones that size. you might remeber it?

2:1 can work.
Keep the keel the right length Storm. Think about it. If the keel = L-W then all the pavilion angles are the same. Do the same with the crown and you have a nice 2:1 stone.
Unfortunately the standard models in DiamCalc will not let me show you.

Please check that the SI1 is eye clean. I once had a SI1 that was eye clean at a glance but my eagle eye was bothered because I constantly scrutinized the diamond. The table is too large which will give you that glassy table glare. I prefer smaller tables and aim for at least VG symmetry.


Colour: H and better because fancies like ECs do show colour. This is subjective to the wearer''s taste/tolerance level.
Clarity: VS2 and better. No point getting VVS because even with a VS, you can''t see a thing and I haven''t seen any eye clean SI1s.
Table: 65% and under to avoid a glassy look and for more fire
Depth: 68% and under to avoid having a smaller diameter diamond
Crown height: 10% and higher is better for more fire
Girdle: Avoid very thin and under, very thick and over to avoid chipping and hidden weight. An even medium girdle is very hard to find so don''t aim for one.
Polish: Very Good and better
Symmetry: Very Good and better

A real magnified picture of the EC will help greatly.

Thanks so much! All of your insight is very helpful.

Also, i know that there has been much discussion on GIA v EGL certs? Would it be in my best interest to get a GIA over EGL?

 

[DIF]

Personally I trust GIA more than EGL.
I trust AGS even more.

Instead of a D SI1, I'd go up in clarity and down in color.
In emerald cut I think you are more likely to be bothered by SI1 inclusions than color of F or so.

To me the 2 or 3 color grades are much more difficult to discern than 2 or 3 clarity grades - especially in grades that border on eye-clean, and especially in emerald cuts which show inclusions more easily than rounds.

 

[UCLABelle]

Oh a "D" emerald cut sounds divine, however, I would look to go down a color grade or two, and up in clarity. Most SI1s (even GIA) emerald cuts that I have seen have slightly noticeable inclusions. I have an "e" emerald cut, with VS1 clarity and love it....

Hope this helps!

 

[chrono]

I am not particular. If the EGL colour and clarity checks out as accurate, why not take the cost savings of the EGL cert versus the GIA cert? That said, I will only buy EGL USA not Israel, Europe or any other. Many other Pricescopers however will only buy GIA and AGS stones.
