Hi! Good to see a trilliant post every now and then  There have been a few more inquiries, but not so many. I am not sure if prescribed proportions will help allot with your search. 'Guess that the most common 'fault' of triangle cut diamonds is having shallow depth (about 30-40% or so) which makes them somewhat less brilliant than one could wish for. Also there are different styles of cut for triangular diamonds that are called at random 'trilliant', 'trillion', 'triangle' and ? Given that he vast majority of such stones are cut in pairs as side-stones, you may be up for a bit of hunting to find a finely cut single stone. IMO, a seller already focused on premium cut diamonds should be of great help, especially given that diamonds of this shape may not be offered off hand as the very popular shapes are. In your shoes, I would do it this way - choose a seller and let them fight the battle  Looking at random, a diamond 50% deep or more, H/VS or better, would catch my attention. From the description on the lab reports it isn't possible to tell what style of cut these are (straight sides or rounded, modified brilliant, trielle?) and I would not know how to guess any further what makes some trillions more brilliant than others. THIS may help a bit too.  My 2c. Best of luck! There were at least a couple of very nice trillion-set rings around here. What do you have in mind ?

Here's a funny bit.... the database here does not list aything with the depth below 40% - and that's already an achievement for a trillion! Usually, there's ... not many of them to put it mildly. The result of a quick search brought a smile of disbelief!  Admitedly, the info available is sketchy... but as promissing as I could hope for from virtual listings like this. I am no expert though - this is as much as I would know for myself...  The search was for: "Trillion shape, 0.7–1.3 cts, D–I color, IF–SI1 clarity, 55–65% depth, 50–70% table" and the result came in like this:  Ana "The greatest experts are only as good as the sum total of what they have seen."

Hi Ana It seems it will be difficult to find a good Trilliant,but I suppose I must start somewhere Ana I like your idea of finding a supplier known for quality and letting them try find something. I think that’s what I will do,and if I may I will keep you guys informed of the progress
If anyone has any images of similar designs they would be appreciated Love you guys  Thelma |

Proportins will not help much. Avoid stones with narrow girdles - especially at the points. Try to get the vendor to polish off a tiny bit before you set as the points break very easily and this reduces the risk. Use an ideal-scope and look for evenly dispersed red thru the stone with no big patches of white see thru. Hold the stones in tweezers and rock them thru about 10 degrees - 15 degrees in all directions and avoid stones that show big windows. There are no all red trilliants thru the scope. ASET scopes are even better than ideal-scope for this task. Garry Holloway FGAA DipDT |
