📢 Are you a diamond dealer or retailer? Stop wondering about how diamond origins are determined. We have everything you need to know in our LinkedIn LIVE series – GEMTalks. On March 19 our Senior Analyst Joshua Freedman is leading the hot topic of “Determining Diamond Origins: Scientific Challenges and Industry Requirements” with GIA (Gemological Institute of America)’s Dr. James E. Shigley for a riveting discussion on determining diamonds’ origins and how to navigate this challenging process.

🌟Did You Know?🌟 Did you know that diamonds can be created from other forms of carbon, including peanut butter? 🥜 While not practical and definitely not your typical method, scientists have demonstrated that high pressure and temperatures can transform the carbon in peanut butter into diamonds. This quirky experiment sheds light on the versatility and surprising origins that diamonds can have, far beyond the typical mine. It’s a nutty idea, but it shows just how amazing and adaptable this gemstone can be! 💎✨ #DIdYouKnow #DiamondFacts #UNIDiamonds #Diamonds #B2BJewelry #FunFacts

Explore the detailed features of an emerald from Davdar, China, in our latest micrograph by Ratin Sriwatthanapitikul (AIGS). This micrograph reveals digitized cavities with brine, halite crystals, and gas bubbles. Cavities of the same morphology, containing the same phases (solid, liquid and gaseous) are one of the characteristics of Colombian emeralds. Such findings contribute to our understanding of gemstone characteristics and origins. 💚🔬 #GemologicalResearch #EmeraldAnalysis #GGTL Dive into our comprehensive gemmological studies in the latest blog post: https://lnkd.in/ekNTksjE Stay informed with GGTL Laboratories for groundbreaking insights into the gemmological field. 💼🌐

ARE LAB GROWN DIAMONDS EVEN REAL? Absolutely Lab grown diamonds are as real as mined diamond they are just made in a different way. They are chemically, physically and optically identical to mined diamonds. In 2018, FTC ruled “diamonds are diamonds whether made in lab or comes out of the mother earth”. Even lab grown diaminds are considered to be better investment because lab grown diamonds are 40% to 60% cheaper than mined diamonds and this does not mean it is a cheaper product, it means it is a better product in cheaper price, sanket patel director at labgreen diamonds said this. GIA Gemological Institute of America certifies the Lab grown diamonds on same factors as mined diamonds, even GIA states that the chemical and physical properties of mined and lab grown diamonds are same. #diamonds #labgrowndiamonds #gia #linkedingrowth #connection #growth

Gemologists and mineralogists rely on the specific wavelength of "sodium light" (589 nm) in the visible spectrum to measure a gemstone's refractive index (RI). For example, diamonds, known for their brilliance, have an RI of 2.417 at this wavelength. In reality, the RI of transparent materials, including diamonds, varies for different light wavelengths like violet (431 nm) and red (687 nm). This variance creates a mesmerizing spectrum or rainbow when light passes through, showcasing the unique dispersion of colors within a gemstone. #Gemology #Diamonds #GIAAlumni #GemstoneEducation #JewelryIndustry #GemCollector #DiamondSparkle #GemologicalInstituteOfAmerica #DispersionEffect #GemstoneScience #DiamondBrilliance #GemmologistLife #DiamondKnowledge #4Cs #Spectroscopy #RainbowEffect

Green Inside the Colourless Diamond 🍀 🙌The nature of inclusions within diamonds provides evidences about crystallisation environment, post-crystallisation processes, and helps to determine the origin of the diamonds, and to distinguish them from the synthetic ones. Among the clouds, knots, needles, feathers, minerals, liquids and so-called "bubbles’’, diamonds can also be included in diamonds. ✌️A 0.87-ct sawn colourless diamond with a negative crystal cavity, open at the surface, contains a loose green octahedral🍀diamond too small to rattle and too large to exit through the opening at the surface of the colourless host☁️diamond. 👉Generally, the green colour of diamonds originates from structural defects produced by radiation exposure or more complex "impurity defects" involving nitrogen (N), hydrogen (H), or nickel (Ni). 🤞According to (Renfro & Koivula, Gems & Gemology, 2020), this diamond inclusion was initially fully enclosed within its diamond host, then partially dissolved as the host made its way to the Earth's surface, but not enough to leave the host cavity. Following this, the diamond probably encountered fluids containing radioactive substances that penetrated through the small opening and caused the green colouration. 📷 Loose green diamond crystal, field of view 3.20 and 4.23 mm © Nathan Renfro; Gems & Gemology, Spring 2020, Vol. 56, No. 1; Video of the diamond inclusion moving inside the negative crystal contained in the host diamond © GIA (Gemological Institute of America) #dimaonds #diamanti #almaz #fancycolordiamonds #fancydiamonds #greendiamond #greendiamonds #diamondjewelry #fancypink #colordimonds #gemology #gemmology #crystalgrow #4c #crystals #diamondinclusions #diamondinclusion #geology #diamondgrading #diamondhistory #diamondeducation #gemseducation

The major differences between natural and synthetic diamonds

𝗜𝗻𝘁𝗿𝗼𝗱𝘂𝗰𝗶𝗻𝗴 𝗼𝘂𝗿 “𝗗𝗶𝗱 𝗬𝗼𝘂 𝗞𝗻𝗼𝘄” 𝗦𝗲𝗿𝗶𝗲𝘀 𝗼𝗻 𝗘𝘃𝗲𝗿𝘆 𝗙𝗥𝗜𝗗𝗔𝗬!💡 Fact#4: Can diamonds truly scratch only themselves on the Mohs scale? Diamond is assigned the highest level of hardness on the Mohs scale, with a rating of 10. This means that diamonds are the hardest naturally occurring substance known. The hardness of a material on the Mohs scale is determined by its resistance to being scratched by other substances. Since diamonds can scratch all other materials, they are assigned the top position on the scale. This exceptional hardness is one of the reasons diamonds are highly valued for use in jewelry and industrial applications. #DiamondHardness #MohsScale #Mineralogy #Gemology #HardAsDiamond #FriedrichMohs #GeologicalWonders #DidYouKnow #GemFacts #ScienceTrivia
