I'm in Vancouver, Canada and am interested in a trillion cut diamond, fairly large size. Does anyone out there know how expensive they are - are they more expensive than other fancy cuts and how easy are they to find?

Does anyone out there have a trillion cut diamond and if so, how do you like it? Are they considered "lower quality" than other cuts? Any response would be helpful!

Lower quality???? No way! The shape is more readily found in small stones used as sides - this is one reason why singles in "side-stone" sizes are to be found at a discount. However, you will find quite a few solitaires with trillion centers. The shape is reputed for giving allot of spread for the weight and it is cut below 60% depth - most often. I do not have a large one, but the largest I saw in a solitaire was about 5 cts and quite spectacular. Teh shape is not reputed to be very brilliant (= as in light return) but rather achieves the look of older cuts (flashes of light and great contrast brilliance, which you may find defined in one of Jonathan (aca "Rhino") posts around here). Here are two examples of what i was talking about: at Jewelry Expert and Diamonds by Lauren (scroll down) Hope this helps...

This could hardly have been a side-stone, right? The stone is somewhat shallow (I'd rather see 55%-60% depth, but this is just an amateur's rule of thumb), but VG symmetry is a rare honor for this shape. Just one case in point.

I rarely see trillions as deep as you prefer. They are mostly cut from flats or macles which do not lend themselves to deeper stones such as the round. Perhaps one of our more research oriented gemologists will have a picture of a macle to share with us and you will see why the trillions are cut the way that they are. The trillion was actually a great boon to diamond cutters as it gave them a way to effectively use this type of rough. Because they are cut from a less desireable shape of rough, they will be much less expensive than a round of the same weight. Wink Wink Jones |

Do trilliants have a bowtie of some sort? How does the shallow depth affect trilliants' performance? An Idealscope of a trilliant? I'm just full of questions today

Macle? sure... here are some better than average close-ups LINK and a different use of (un-cuttable) diamond roungh And one pic under the Iscope (LINK). I would expect a trilliant to look as "sparkly" as a good OMC or a good oval (present on that page too). 'Bow tie' here would be the sector just in the middle of the sides - so a three-sides bow-tie  However, I find it less obvious than in any other shape - maybe because the shallower depth of the trillions do not allow these areas to become "reflectors" (black under Iscope) like they might in ovals or radiants. Actually, I thought "bow-tie" is more theory than visual impression for this shape, but the IScope images seem to show "something" in that area... for better or worse.Ana "The greatest experts are only as good as the sum total of what they have seen."
