“I’d like to give you the whole world on an emerald-studded platter.” (Michael to Emma in Ended by Emerald)
Gemologist Emma Goldsmith doesn’t have an emerald-studded platter, but she always likens looking into the depths of a fine emerald to the weightless freedom of slipping into a tropical ocean. Like a tropical reef, the inclusions so often found in emeralds presented a world of fascination to the viewer. And that dive into the rich green, the green that has been the standard for green for centuries upon centuries, was always a magical experience.
Clarity is one of the major quality factors for gemstones, so the gemologist taking that magnified dive into the interior of the gem is hoping to see… nothing. Flawless emeralds are extremely rare and are valued accordingly. However. Unlike some gems which have few inclusions, emerald is known for a plentitude of inclusions. This
plentitude is commonly referred to as jardin or garden, and is composed of inclusions of other mineral crystals, of liquid inclusions, and/or gaseous inclusions.
From a conversation between Emma and a visiting gemologist:
“I’ve read about that, of course, but the first time I actually saw the ‘garden’ in one of your emeralds, I almost fell off my chair. I can really see why it’s called the jardin. Those inclusions really do look like plants in a garden.”
From my own personal history:
Picture this: You are selling antique jewelry at an antique show. Among the fine pieces you offer is a pair of emerald earrings. They aren’t old enough to be antique, but they are vintage. The emeralds are both heavily included and very large. They are, surprisingly, untreated stones (which is very good).
It’s day number three of a three day show and you’d really like to sell more (as would every other dealer present).
You can’t help crossing your fingers when you think about the lady who has come back to look at the earring a couple of times already… And here she comes again. Yes!
She tries them on—again. You hand her your mirror (your lovely antique Art Nouveau silver mirror) but she waves it away. She walk across the aisle to the full length mirror of a neighboring vendor and looks at herself.
She is not alone. Everyone present is transfixed by the vision of this lady—slender 
and lovely and blonde and tanned and wearing white. Blonde, tan, white, plus the startling green of the emeralds.
I think we call this a win-win situation.
