    GIA-IGI Certified Lab-Created Diamonds Come to Sale With Lab Grown Auctions

    Lab-grown diamonds are human-made synthetic stones produced in a controlled environment in contrast to naturally-formed ones. They are made of the same material as the ones found in nature with identical physical and chemical characteristics. Antoine Lavoisier, the central figure in modern chemistry, first discovered this similarity. Thereafter, several scientists, including James Ballantyne Hannay and Ferdinand Frédéric Henri Moissan, attempted to convert low-cost forms of carbon into diamond. The upcoming sale from Lab Grown Auctions will offer a variety of laboratory-created diamonds. One of the highlights is a pair of diamonds, weighing 35.50 carats. The cushion cut diamonds are IGI graded and have a "crushed ice" or needle-like facet pattern. Another noteworthy piece is a heart cut gem, weighing 21.53 carats. The heart-shape diamond was first mentioned in the 15th century in a correspondence between the Duke of Milan and his confidante. An oval cut stone of 17.23 carats also leads the listings. The elongated form is a combination of the classic round brilliant and distinctive modern styles. It appears larger than its actual carat weight.
