    The last you mentioned lab grown emerald is only possible with the flux growth method in platinum crucible due the fact a big difference in melting points of his constituents does not permits Çzochralsky or flame fusion . And FLUX NEED SEVERAL MONTHS TO GROWS EMERALD CRYSTAL SO IS THE MOST EXPENSIVE WAY. The only other way of growth for emeralds is hydrothermally

    hello thank you for this informative video. My emerald is a lab-grown type from the source which they said its through Hydrothermal process but when it was tested under the GEMOLOG color gem tester it was IMITATION not a synthetic. But they argue when I have shown them the result that it was really a lab grown and they are also known for making Moissanites. Why is this happening under the tester. Is there an alteration of chemicals compared to a natural if synthetics or lab grown have the same chemical compostion the natural ones?
    thank you

      Hello, Thanks for your thoughtful question. It sounds like you're encountering some confusion with the testing results. Lab-grown emeralds, like those created through the hydrothermal process, should ideally match the chemical composition of natural emeralds. However, certain testing methods might misidentify them as imitation due to differences in their growth patterns or inclusions. Gem testers often rely on specific properties like light refraction or inclusions to determine authenticity. If the tester you're using has limitations, it might not accurately distinguish between synthetic and natural stones. Additionally, if the lab-grown emerald has a different optical signature or fewer inclusions compared to natural stones, that could lead to misclassification.
      It's always best to get a second opinion from a qualified gemologist or use multiple testing methods for a more accurate assessment. If you can, try to find a lab experienced in distinguishing between synthetic and natural stones.

If u can buy u buy If cant just stay or wait . Buy Swarovski at this point . Don't waste money . Swarovski is glass policrystalline material but is the Original not an imitation .

      @@chuaycamm consider this: top quality hydrothermal emeralds as coloring dope in their colombian type uses Chrome and vanadium instead of Fe exactly like colombian mined stones, the process needs 2 months and pure gold lined sealed autoclaves at around700c° under pressure. The only one ONLY ONE that makes flux grown emeralds takes up to a year solid platinum crucibles at 1300 c° , do u think those scientists , engineeres , chemists waste time and so expensive resources to grow imitations ? You must be afraid when u hear "...yes but the WARM color of the natural one..." . I say " stupid idiot the color of mined and the lab created are the same ! ROOM TEMPERATURE ! Or " shine is better " other stupid says , does'nt matter mined or created they shines better when inclusion free and the cut follow the right plane of growth and not the the carats "save" .Those people are loosing the war VS lab created so their last resource is speaking Black Magic voodoo

    Love your description of how these 3 different types of created emeralds are made. I am familiar with the lab grown varieties-flux, flame and chol, but the other 2 were new to me. Isn't there also a hydrothermal created emerald?

      Thank you for your kind words! I'm glad you enjoyed the description of the different types of created emeralds.
      Yes, you're absolutely right-hydrothermal emeralds are another type of lab-grown emerald. Hydrothermal method and recrystalized methods are similar, Both techniques aim to replicate the natural conditions under which emeralds form, using high temperatures and pressures to encourage crystal growth. In the hydrothermal method, emeralds grow from a solution that mimics the natural fluids found in the Earth's crust. Similarly, the recrystallized method involves dissolving raw materials and then slowly cooling them to form new crystals. Both methods produce emeralds with remarkable clarity and vivid color, closely resembling their natural counterparts. It's fascinating how these techniques blend science with nature!

      The 2nd is an hydrothermal but this guy know 0 about gems . The 3rd is only possible with flux method (the most expensive , several months of growth) Czochralski and flame fusion methods are impossible with emeralds .the 1st doublets the cheaper are no more in use , were used in the 60s & 70s . Flame fusion and Czochralski works with corundums (sapphires and rubies) spinels tourmalines quartz(topaz ametyst) and others. Hydrothermal was mostly used with beryls(emeralds acquamarines) but in Russia the university of Novosibirsk and Tairus succesfully uses Hydrothermal autoclaves to create (crystallize) blu sapphires and rubies . Right now the best lab emeralds are colombian hydrothermal from H.K. and Thailand and at 3 times of their cost is the only factory in the world (in Japan) which still produces flux grown emeralds. Lab gems are way better than their natural counterpart enviromental friendly eco friendly war free slavery free...ect ect , they should be the only choice of today people

      @@elizabethcarter1175 emeralds can be grown in 2 methods only . flux melt in platinum crucibles it can takes up to a year of time at around 1300 c° of heat , no pressure involved and today only a productor use this way to make some samples (if u Google "emeralds flux grow) u need time to find , if u find ah ah. The other method is HYDROTHERMAL uses an autoclave with seeds of beryl acidic hydrosolution around 400/700 c° of heat and pressure (the autoclave is sealed) . Emeralds cannot be grown in any other way ! In nature mined emeralds comes from magmatic and hydrothermal enviroments under earth crust at magmatic and premagmatic levels in lab are grown exactly those ways better looking no need to be oiled or glass filled same inclusion of water (like colombian) of platinum and somtimes little craks exactly like mined . Mined no have platinum inclusion of course ,they can shows "gardens of organic waste of the Jurassic era" ...maybe , on my finger I prefer platinum , honestly. I reapeted 1000 times CRYSTALIZATION IS ALWAYS THE SAME DOES'NT MATTER WHERE IT HAPPENS IN THE UNIVERSE it follows always the same rules . If u want pictures of samples just ask. Is time to cose the mines and start create real job opportunies no slavery wars and all the rest. Bye have a nice day .
