The newborn green pear is on the left.
He is a 0.19 Fancy Green SI1.
The new green pear does have patches of color visible near the bottom and is rather shallow with windowing but I really like the color, and the price was great.
Surprisingly, the new 0.28 Fancy Intense Blue Emerald Cut looks larger than the 0.33 Fancy Vivid Yellow Asscher behind it.
The Fancy Deep Purplish Pink EC is 0.27 ct. but is a lot deeper than the 0.28 Blue.

I had to look up ROY G. BIV but yes my project has been to show the graduations of colors in the rainbow with natural diamonds.
I can't quite articulate why, but this project resonates deeply with me on many levels.
Lori, I'd like to get a good pure orange, a cleaner fresh pure yellow and I wouldn't turn my nose up at a nice bubble-gum pink emerald cut.
BTW, I just found out several of them exhibit phosphorescence, which is different from fluorescence.
(Today's thread on RT got me curious.)
Fluorescence is when they glow when UV light is present.
Phosphorescence is where they continue to glow after the UV light is turned off.
Witnessing phosphorescence is kind of a hassle.
The light given off by a phosphorescing diamond, at least mine, is VERY dim and VERY fleeting.
My strongest one lasts perhaps 2 or 3 seconds as I watch it fade to dark.
The more faint ones last less than a second.
Since light given off is so dim you won't see it in a normally-lit room, just like you can't see stars during the day.
I had to sit in a dark interior closet for a minute or so to let my eyes adjusted to the dark, something you also have to do for star gazing.
I think to fully-experience a diamond's phosphorescence it takes around 45 minutes of sitting in the dark for the eyes to reach their full sensitivity.
I used this UV light:
FWIW, I'll report later on the relative strengths and the exact color I see and how/if it phosphorescence relates to the fluorescence of my collection.
BTW my asscher (GIA F VVS2 2.26 ct med blue fluor) has very substantial phosphorescence. TOO COOL!
I was hoping that my blue diamond would phosphoresce red (I've read that they do) but I don't detect that, yet.
Maybe I need to let my eyes adjust to the dark longer to detect it.
Gosh! What a dork I am!!!
I doubt phosphorescence is bright enough to capture with a camera but I'll give it a try.

If I didn't already have my Fancy Red and a Deep Purplish Pink I'd strongly consider it.
It has fantastic color.
Fascinating unique cut too.
It is a hybrid of emerald cut and radiant.
GIA calles it, Cut-Cornered Rectangular Mixed Cut.
What I'm keeping my eyes peel for now is a pure orange, a fresher more pure yellow and maybe a blue with stronger color.
It will take years.
