Great value no-oil Colombian Emerald?

There are several items in my long-term bucket list, and one of them is a no-oil Colombian emerald of good colour. I stumbled across this a couple of weeks ago, and thought give a heads-up in case anyone is interested, given it seems to be an excellent price fitting the bill of no-oil Colombian.


Some will wonder why do I flag it here rather than claiming it for myself? Well, taking this would eat into rest of my gemstone budget for this year and likely some of next year's. But in seriousness, I understand for one thing that this vendor doesn't come recommended by the forums. While it is a detracting factor, what actually bothered me most are suspicions for fissure on one corner of the face that I was worried might reach the surface, and inconsistencies about colour intensity on the website default description vs in-house appraisal.

I did flag the concerns with the vendor customer services and they got back to me after a few days saying the colour intensity description should be read as intense and that they will amend the appraisal to reflect that-but hasn't happened thus far, more than 10 days on. They acknowledged the inclusion appear to reach the surface on one side; while I appreciate their candour and will look into their other no-oil emeralds, that seem to be a deal-breaker for me, more for mind-clean sake really (I know, sounds contradictory given my views on Burmese rubies few days ago but that fissure can lead to the stone shattering at some point...). Shame, because it would've ticked all the other boxes for me. Mind you the surface-reaching inclusion is quite minute so it may be good enough for some people, putting the photo up in case anyone is interested.

Yikes that pricing!!!!!

Try this


Or


I did. But none of no-oil stuff, and for Starruby, not much there at all.
 
Is the surface inclusion on the table something you can remove or fix with a gentle polish, sacrificing tiny bit of carat weight, or would that risk damaging the stone beyond repair?
 
If you want a truly decent no or minor oil I’d recommend three vendors:

No, that inclusion goes deeper into the stone. You can see it better in the 360 video.
Emeralds are a brittle gemstone, they have a tendency to “cleave” if they sustain a substantial whack. That’s why you have to be careful with emeralds set in rings.
With a surface reaching inclusion you would have to be mindful if set in a ring that an accidental knock could take a chunk out.
It’s a lovely emerald but the price is :-o

Yeah got suspicious after the video. Thought it reasonable price for no-oil Colombian, but as I said, no for me with that surface reaching fissure unless easy way around it!

Easy way around is to use a modern resin to protect the fissure. Usually when a knock takes a chunk out, the emerald is a lot more included than your pictures show.

Honestly, I remember when professionals such as @PrecisionGem were commenting about how paranoid some people are about the inclusions. If it was cut, the gemstone must have already taken quite a lot of pressure and heat, even if it is surface reaching. The only thing I'd be personally concerned about with those surface-reaching inclusions in terms of stability is abrasion by dust, since I'm not one of those people to dedicate a lot of time to wearing and cleaning my rings. However, @Sydneyphoenix, emerald is above Mohs 7, so I wouldn't be worried about abrasion by dust. I'd only be worried about whether that price tag makes sense for me as a collector.

Thank you. Hmm I don’t mind inclusions in general as long as they are not eyesore, but though surface-reaching inclusions are bad, not only for emerald but even in corundum? Things to think about…
 
Can some explain the obsession with surface reaching inclusions vs those that don't reach the surface?
 
Gene: I would be inclined to think a stone with a surface reaching inclusion such as a fissure or crack, would be more likely to catch on something and be damaged. Whereas perhaps an internal inclusion which had resolved itself internally would be less inclined to affect the stone's structural integrity, especially at the surface?

But hey, you're the guy who cuts them! What are your thoughts?
 
Table surface reaching inclusions in emeralds are a big deal breaker for me.
 
If the inclusion wasn't to the table and the price is as advertised, would that be a good deal? I'm not going for this one, just want to see what to expect price-wise for this kind of stone.
 
I think the pricing is about 20% higher than what I would want to pay. You could wait for the vendor to have a sale and buy it at a lower price. I actually quite like the look of that emerald and think the surface reaching thing you're pointing to doesn't really detract very much from the stone, not would it make me concerned about durability or having it catch on something. It's not like it's a long fissure that would potentially widen over time. My 2 cents.
