Nice vedeo

[@MrFracknight]

You right, there is no reason to buy from Thailand if you can have a provider in another country. The fact is that many Rubies from Africa, Madagascar and other places are sent to Bangkok mostly for treatment. For myself, I am working with a friend in Bangkok over 10 years and I can find best quality and prices there. Buying gemstones in Thailand ask you to have a deep knowledge in gemology and in the trade. I was in BKK in February and I was surprised to see the prices rising for nice quality.

[@JosePalma-j6r]

Thank you so much for idia

[@MrFracknight]

The stone at 4:15 is a nat. corundum called Songea from Africa. The stone is not only heated, but heated with Be that is considered as an heavy treatment. Thats why the price is low for a 2.66 cts. If the stone was totally natural with no treatment price will raise up to 10 to 15'000$US per carat because it is very rare to find a ruby with such clarity and color. The difference between a natural ruby just heated compared with a no treated depend of the origin and ct, around 10 to 20% lower.

[@zamoragemstone]

I am glad if you are here, coz it's limited for us sharing knowledges without any gemstone physically.. Thanks

[@MrFracknight]

Hola Ignacio, Aquí en el D.F. es muy difícil vender piedras de color. Necesitas tener clientes que tengan mucha confianza en ti y eso no es fácil. El mercado aquí es mejor para los diamantes pero no los de muy buena calidad. En cuatro años he vendido más piedras sintéticas que naturales. Saludos y suerte.

[@MrFracknight]

I di not talk about the Flux synthetic ruby as they are rare on the market today. On another side, you need a gemo stereoscope to check and learn about the specific inclusions for each producers. A "spider web" can be seen in natural rubies. Strong magnification demonstrate the difference between flux remnants in flux and fluid inclusions of healing fissures in natural rubies, we are talking about power 100X, then the loupe is not enough until you really are a pro. The best way is spectrometry.

[@MrFracknight]

The cutting is not very expensive, but if the rough is very nice you have to find a very good specialist to be sure that your rough will be cut following the rules. The ruby show pleochroisme and have to be cut the right way if possible (table perpendicular to C axe).

[@lorenzacampanini4941]

[@MrFracknight]

I checked in deep and I saw that Aquamarine has been synthesized by hydrothermal growth in Siberia. Under magnification it is possible to see the limit between the near colorless seed and the light blue Beryl. There is other type of inclusions typical of hydrothermal growth. It is easy to check them out. I think those Aquamarine are rare on the market and today it will cost to much to make and market them. Synthetic blue Spinel is cheap, clean and easy to make with flame fusion process. Regards

[@kathryndailey3995]

Thank you! You helped me from buying a glass ruby.

[@howbriblue]

THANK YOU VERY MUCH.

[@MrFracknight]

Unfortunately UV can't be diagnostic to make a decision checking only one stone, but the glow from synthetics in mixed parcel of natural and synthetic rubies will be perceptibly stronger. The loupe in some case can help too, but I know many people who are making mistakes, especially with the FLUX-MELT Corundum like Chatham, Kashan, Ramaura and Knischka stones. As they are hard to make and need two to eight months to grow (6 hours for flame-fusion) , today it is rare to find them on the market.

[@olivier-pierredebelmont.3630]

Hi oli. My name is also olivier,so some simulitude here .as you,i also speak french.bonnea videos je m'abonne!

[@algalverge]

great videos thanks for all your work can you make a video about diamond testers and how to use them?

[@kamrankhanDenver]

Can you please make video about Emerald and tell the difference of emerald origin ? Thank you !!!

[@gigie555]

How about ruby that has undergone only heat treatment. I understand it has been accepted practice for centuries.

[@MrFracknight]

In gemology we say that only the miner know where a rough come from. No pro gemologist will stat an origin on a certificate just on your word, unless the stone speak by itself. The origin is a big market value especially for the rubies and I have seen may "pro" making mistakes about it. It's not an easy game.

[@MrFracknight]

Hi, usually the price for rough boule flame fusion ruby or sapphire (Corundum) will go from 200$US to 300$US for a kilo, all depending on the quality. Best quality do not have any gaze bubble or powder traces. The price can go up to 3000$US the kilo depending on the color of the corundum because some color are difficult to obtain, like the orange, yellow, some red, etc. PS This is the wholesale price, not easy to obtain if you are not in the trade.

[@pavlebaljevic2787]

I tried to contact Djeva to deliver me, but no one answers. Are they still working, producing ruby boules?

[@MrFracknight]

Hi, sorry for late answer, I was traveling... Yes the heat treatment is an accepted practice. It is OK as long as the process is disclosed to the customer, like any other treatment. The impact on a heated ruby is mostly on the price.

[@zamoragemstone]

There're so many synthetic rubies in the markets nowdays, make sure you have loop and UV light before making decision.. By using a loop u can clearly see internal spider web and the natural rubies should be fluorescent under UV light in dark room.. Thanks

[@MrFracknight]

Hello, The best you can do is to find a gemologist that have a very good knowledge on colored stones. He can make you a certificate that will stat if the rough is natural and no treated (or treated). If there is enough information inside the stone to give the origin (inclusions), then you can have the origin on the certificate. BUT, there is very few peoples that have the knowledge to do that. The best for rubies are the AIGS lab, the GIA lab and the GIT Lab (university) in Bangkok.

[@dadrules714]

It's my understanding that most ruby is heat treated to improve color. some estimate up to 95%. An unexpected result of heat treating is some glass fill of inclusions(found when heat treatment started approx 1200 AD). Would this still be considered GF? How does it detract from value? very informative thank you

[@MrFracknight]

Hello, Heat treatment is not only to improve color but clarity too depending the case. What do you mean by GF? Not sure I understand that. Today, just heat treated ruby, even the one with borax trace do not loose much than 10 to 20% value as they are still rare. With the new lead glass treatment (composite ruby and more recently they do composite blue sapphire with Co for the color) that is spreading the market, basic treatment like heat or glass filling ruby (like to close a cavity in the cristal) are rare and have great value. Ruby cristal is very very rare. In the lab, the last year (2013) I have seen only 5% real ruby of very good quality and 0% fine quality the rest is heavy treated or synthetic. Contact me on my lab email if you need more info.

[@simpleasasunnyday]

Great videos, keep the coming :)

[@MotherEarthswarrior]

thank you very much Sir.

[@MrFracknight]

Hi, I'll try to make that as soon as I am ready. But I have a lot of work in the lab right now. I will make some other video about the diamonds that's my plan for, I hop, a near future.

[@mariashepard6107]

I have a ruby bracelet and it’s sterling silver but the ruby stones are covered in gold foil on the backs of them. It was bought from a jeweler in 1963. I don’t remember how much my husband paid for it. So my question is , could the rubies be real?

[@ignaciotubo]

[@dunhillwatchlighter]

Hi Olivier, thanks for the info. So natural is depending on colour and size etc. not heated, lets say 5000$ heated would be around 3.-4000$ and be heated only 500$ a ct. So big difference in Price between only "heated" and Be-heated? Not so big Price differnce in "heated" and not treated?. Thanks I bought the book GEMS you recomended. Many pages.... I just read quickly and the say that 2-phase inclusions also can be found on emeralds.... I always thought that 2-3 Phase inclusions are sign of..

[@zamoragemstone]

Thanks, for me rubies are quite simple to know between synthetic and the natural, by using a loupe, you can see spider web in great details .. There're also other gems almost like it such as red tourmaline, rubelite, chatham etc, nevertheless it looked contrast by using a loupe..

Is there some way to determine which country the Rubies came from?

[@dadrules714]

Hello Sir How are you? I've been speaking with GIA graduates on determining LGF in star ruby/ sapphire other rutilated Mtrls. Not ONE can tell me the best way to determine LGF in these stones. In 2002 a Thai Mftr notified the GIA of his methods and plans of marketing heated / LGF Star mtrls. Most of the information i've read / referred to is based upon translucent mtrl. I have a 12 ray black sapphire i bought very reasonably. however the SG is 4.072 raising an eyebrow. I see no odd deformations in the surface But I can't see into it well enough for flash yellow pocketing or bubbles Ive tried backlighting. SO i'm coming to my favorite expert Short of an electron microscope what is the best method for determining LGF in Opaque material? Could I use aqua regia to etch the poly /LGF? ( I realize it would destroy LGF mtrl) what would this do to genuine corundum? Thanks Rob

[@MrFracknight]

Market on the colored stone is not like for the diamond with a price list like Rapaport. Price could change from one day to another. Today ruby not treated is extremely rare on the market and very expensive, especially the one from Myanmar (Burma). Just heated stone are accepted in the market and even the Songea of very good quality and color (like in the video) is very expensive now and could reach easy 500$ per ct.

Oliver! I would like to congratulate you your videos and the willingness to share your knowledge online. I would like to ask your opinion in two pieces. I am buying a present to my girlfriend and even if she doesn't understand at all about gems or treatments I would like to buy her a ruby ring that I know its not artificial or filled with glass.

[@shangsopouneme6796]

Hello Mr Olivier I have one stone which weight around 40cts but i'm confused whether this stone is spinel or pigeon blood ruby. How can i differentiate between them?

[@MrFracknight]

SG: Ruby =4, Spinel = 3.6 RI : Ruby = 1.76-1.78, Spinel = 1.71-1.74 Spectrum is diagnostic for Ruby CS: Ruby is trigonal, Spinel is cubic, very easy to make the difference with a simple polariscope.

[@keshawsawarthia2205]

Dear sir, as you said that in a real ruby we wont find bubbles inside and some of the ruby which you have showed us there is bubbles inside it... I did not get you exactly what you want to say. please clear me ...

[@rhiannish]

bubbles are for glasses.. in a natural stone or ruby it is "inclusions" if they wanted to hide the cracks... almost all stones have small cracks inside it and the gem makers try to hide it by adding fillings to the stone. or if you found a crack inside your gem then most probably it is not glass.

[@MrFracknight]

Hi, I would NEVER buy online. 1) the picture you see is never the one you'll get. They make one picture the best they can and after they sale the bad stuff base one that picture. 2) They do not disclose anything about treatment and for a ruby clarity I (Included) and for the price I saw, that surely a new glass treated ruby. 3) You never set in a 9K gold a ruby, unless it is a piece of crap! Good luck.

[@zamoragemstone]

Thanks for infos

[@dire67]

Does untreated also mean unheated?

[@romfeastore]

Not always...it can be unheated and treated like oiled etc.

[@dire67]

Hi nice video. Can i know what is the best magnification if iam to buy a gem microscope? Should it be as high as 80X or low as 30X is enough?

[@MrFracknight]

Hi sorry for the delay I was on the field. In gemology we are using 60X as a standard.

[@66mohammed]

Is 80x too high? Also whichbia better from this combination ? 10x 20x 30x 60x and 20x 40x80 ?
