Your videos are very useful and provide lots of information. I have received lots of help after watching this post, please continue to share this kind of information. Thank you.
Thank you Henry, We will try to post some more videos as time permits. Been really busy the last few months and I do want continue educating people more about the beauty of gemstones. Thanks again for your kind words. Best Regards, Tarun Gupta, GIA GG
I use an ice cube tray, place an emerald ring in each cube spot. Add warmed Johnson's baby oil to cover each ring and let set overnight. Wipe them off in the morning and put them back away. I do this 1 or 2 times a year, but if you wear them a lot, I would oil them another time through the year.
When preforming or buying a rough stone it has been oiled or not. When polishing it is not absolute that your cut will have not surfaced inclusions or fractures. Oil is often used. Grade of rough
Video of ruby has already been done. You can see it here: ua-cam.com/video/XODG8dB6phE/v-deo.html . Will do the sapphires (yellow and blue) soon. Regards, Tarun Gupta, Graduate Gemologist (GIA)
@Kendall Angelo curious how you responded to a comment that was posted 22 mins ago on a comment from 2 year ago that has nothing to do with what either of you two talked about
i do have emeralds here as base on assay report it is natural emeralds its so dark i think it was intentionaly buried under. dont know where can i sell it😅
I recommend reading our blog post regarding this subject if the video didn't make sense. Link is provided here: buygemstone.info/2013/06/17/natural-emerald-buying-treatment-guide-how-to-buy-and-tell-the-difference-between-100-natural-no-oil-minor-moderate-and-significant-treatment-emeralds/
Hi Adarsha, Cost will also depend on the emerald origin, color range, clarity, and treatment levels. Do email me your budget range and I can check for you what is available in the market. Our email address is sales@thainativegems.com. Regards, Tarun Gupta, Graduate Gemologist (GIA)
Gas bubbles are natural inclusions or caused by foreign fillers (like oil, wax or resin) being filled in emeralds to hide their inclusions. Unfortunately, we currently don't have a microscope camera which is clear enough to show this. I do recommend to reading our blog post which has an image of a gas bubble trapped inside a treated emerald - buygemstone.info/2013/06/17/natural-emerald-buying-treatment-guide-how-to-buy-and-tell-the-difference-between-100-natural-no-oil-minor-moderate-and-significant-treatment-emeralds/ Best Regards, Tarun Gupta, Graduate Gemologist (GIA)
@@ThaiNativeGems no you are wrong, bubbles could be of natural origin ... In fact , these sort of inclusions are very common in emeralds... If the diameter of gas bubbles are same and they follow a regular pattern then it may be due to treatment which prompts for further quantitative verifications
Thanks for clarifying. You are absolutely correct that natural emeralds have two-phase inclusions which has "natural" glass-bubble. Thanks for clarifying and correcting my earlier "generalized" statement. Best Regards, Tarun
I will try to get some. They are definitely a lot cleaner and slightly more bluish in color. I personally love Russian emeralds as well. Regards, Tarun Gupta, GIA GG
Hi Flower, 'Same' is very subjective. Have the emeralds been certified from reliable third lab (GIA, GRS, etc.,)? Also, how is actual color, crystal clarity (transparency ranges base on clarity defect, cloudy appearance, etc.), treatment levels (which this video explains), emerald origin and cut grade. Only by taking all these factors into account we can than determine the price range. Regards, Tarun Gupta, Graduate Gemologist (GIA)
I really dont understand oiling. Would people not buy it if it was not oiled? I greatly prefer the look of the gem natural with surface cracks and inclusions visible. Its like a finger print unique. It seems to me I would save the very high quality natural stones and oil the lesser ones.
I completely agree and as a gemologist I love seeing natural inclusions as well. But unfortunately most consumers in the market don't. Most prefer not seeing any inclusions. Thanks for your comments. Best Regards, Tarun Gupta, GIA GG
Hi Kevin, I do agree with you, however, the reason why it is normal practice in the trade to add any 'foreign' substance in emeralds is so they are look 'less' included and therefore more salable to end user. Emeralds in general are highly included gemstones. This is also reason why high quality 'no oil' emeralds are so expensive and so rare. Regards, Tarun Gupta, Graduate Gemologist (GIA)
This video just talks about probability of oil (or other filler). There are emeralds which have surface openings in which neither the miner or cutter has used a filler. To know, one must use a microscope with different lighting or more sophisticated testing equipment. I have cut and supervised the cutter of thousands of of emeralds in my lapidation and on rare occasion have elected not to treat even when it was possible because of the premium which is paid for fine untreated emeralds.
Hi David, thanks for your expert comment and insight. I completely agree with your comment and unfortunately I couldn't portray in this video the 'flash effect' which you should check through different lighting under the microscope. I did also generalize that if one does see some surface reaching fractures that they will be fillers as this usually the case with 99% of emeralds in the market. Of course, if you are sourcing the emeralds directly from the mine and supervising the cut process I am sure you will get some untreated no oil emeralds, which has surface reaching fractures. I really do appreciate you pointing out some of my generalize statements and clarifying it.
Depends on ring setting design. There are settings like 'bezel' settings which secure an emerald cut stone better. Example you can see in this video: ua-cam.com/video/HTzN6jM4uzI/v-deo.html Regards, Tarun Gupta, GIA GG
Recommend sending your emerald to professional gem lab. You can read about different labs in our blog post: www.buygemstone.info/2017/03/10/what-lab-or-certification-is-the-best-for-checking-your-expensive-ruby-sapphire-or-emerald/
The issue is not emerald should be in oil or not. It is other more aggressive treatment people do which hurts emerald business, like wax, resign or 'color oil' (not clear cedar oil). This makes everyone not trust even regular oil emeralds. Also in terms of rarity having a 'no oil' is a prestige point and therefore commands a much higher price. Thanks for your question & Best Regards, Tarun Gupta, GIA GG
Pretty sure it is a Zambian as the wholesaler we bought the stone from got the rough directly from Gem fields auction. Thanks for your comment anyways. Regards, Tarun Gupta, Graduate Gemologist (GIA)
Thanks Richard for your comment & opinion. Agree with you completely. These are trade-off we always see in the trade for expensive "big" three gemstones, whether to cut the stone perfectly or save the maximum carat weight.
I am from Afghanistan Panjshir and we have mountain of Emerald but no security and good machines to mine them correctly. so they put an explosion and destroy 90% of the Emerald

Thanks, Khalid. I guess my 'accent' does not suite you. :) Yes, two of the emeralds are from Zambia (so Zambian is the correct term). Cheers, Tarun Gupta GIA GG
Hi Michael, completely agree with you that this video doesn't cover carat weight trade-offs. The purpose of this video was to focus on emerald treatment levels and to see how and tell the difference between each level of treatment (no oil, insignificant and minor to moderate oil stones) and how this effects the value. Now if we include, carat weight ranges, color and clarity this makes discussion a lot more complicated and this is a reason why buying color gemstones requires some skills, experience, good pair of eyes and some luck. Thanks for your comment anyways.

Colombian emeralds from usd 1000 to usd 20000 per carat depending on quality ,and treatment .
I have been offered some raw emerald crystals from Afghanistan, how can i spot any treatments, when they are raw?
You can assume there is already some treatment in them. No treatment emeralds aren't very attractive in general.

Why emerald have gas bubbles .
you must make video for this and make us understand

I have a dimension of Emerald how to contact you
They are natural or lab made
Rizwan Baloch All three stones are natural.
Right I don't agree with adding or removing anything. So.. no touching the oil and nothing insincere (wax) on the throne. No inclusions.

Emerald cut is the weakest setting for a ring.

Hi Michael, completely agree with you that this video doesn't cover carat weight trade-offs.
