I could get a 1.92 I SI1 onfor ~$18K, but vs this I SI1, I gain some better light performance, I nudge down appreciably under 2ct (a target/requirement for the recipient), and I trade these inclusions for other non-ideal inclusions.
There are no 1.95's out there... believe me, it's been what I've been looking for from day one lol
Help me understand this....1.92 is too small, but 1.95+ is cool?
If you aren't aware, carat weight is a function of length, width & depth. The exact proportions of each stone will change those elements. Below is the exact formula in case you are curious:
average length x average width x depth x 0.0061 = estimated carat weight
1.918 I-VS2 @ $17,237 wire
Diamond | 1.918 ct I VS2 A CUT ABOVE® Hearts and Arrows Super Ideal Round Cut Loose Diamond AGS Certified | 3855430
I think we'd agree, this stone performs like a champ and has all the pedigree to prove it. Based on your comments above, your main reason for rejection is size.
So let's have some fun.
Below are the dimensions (L x W x D) of the two stones you originally picked and the "too small" 1.918 that I linked above.
- 2.01 I-SI1 = 8.08 x 8.10 x 4.99mm
- 2.01 H-VVS2 = 8.10 x 8.15 x 4.90mm
- 1.918 I-VS2 = 7.97 x 7.97 x 4.92mm
Also notice how the 1.918 actually has more depth in a smaller spread (LxW) than what the 2.01 flat top has? Granted, not much more depth, 4.92 vs 4.90. Despite the smaller spread, the 1.918 has more depth because it's maintaining a better c/p angle relationship. The stone is cut to maximize light return and not have leakage.
When you start to cheat, performance degrades. Unfortunately, it's a greed driven world so cutters are incentivized to cut for weight (profit$$) and not beauty. This gets especially true when you are on the verge of a magic carat weight. Fudge a little this way or that way and we go from 1.98 to 2.00 or 2.01 and the profits boost. Most consumers are none the smarter, so right or wrong it flys.
But back on topic. In regards to the dimensions of all 3 stones, let's agree that the 2.01 I-SI1 would be a fairly representative size of a 2 carat stone. With that said what is the true difference?
- 2.01 I-SI1 = 8.08 x 8.10 spread, or 8.09 average
- 1.918 I-VS2 = 7.93 x 7.97 spread, or 7.95 average
- Difference = 8.09 - 7.95 = 0.14mm
- 0.14mm = 0.005511811 inches
- 1/128th inch = 0.0078125 inches
- 1/256th inch = 0.00390625 inches
- 1/192nd inch = 0.00520833 inches
- To put this in comparison, most rulers go down to 1/16", maybe 1/32" if you have a fancy pants model. Now think about how small that is. And 1/192nd is about 3 magnitudes further down the scale.
- On average, a human hair is roughly 7mm thick. So in reality, the 1.918 is about 2 hairs lesser in diameter than the 2.01.
What your eyes likely will appreciate is a stone that is a complete & total sparkle bomb. Your (future) wallet is going to appreciate having bought from a vendor with a killer upgrade program. You and your wife are going to appreciate all the compliments given about the beauty of your stone. Not to mention, when stones produce maximum light return, they reflect EDGE TO EDGE, making them appear larger even in less than ideal light.
