Green is a super rare color in diamonds. Pure green is as rare as pure blue.
We love stone like this where a modifier decimates the price, as compared to a pure green.
When there is a modifier, the actual shade of green can vary to a wide degree. This particular diamond looks green. A lovely light lime green.
The strong blue fluorescence is an asset in the way this diamond looks - especially in terms of the perceived color.
There is a little garden of carbon crystals, that comprise the SI1 clarity.
Thankfully, none of these tiny crystals is visible to the naked eye. Plus the way they are dispersed, there is no impact on brilliance. Did I mention the cut which is just so nice!
