Gemstones: Natural vs. Synthetic
Natural gemstones are formed over millions of years through geological processes, while synthetic ones are created in labs within weeks. Despite identical chemical compositions, synthetics often have fewer flaws and are less expensive.
Rare Gem: Painite
Painite was once considered the rarest mineral on Earth. Discovered in Myanmar in 1951, only a few specimens existed until recent discoveries. Its rarity and unique orange-red color make it highly valuable to collectors.
Color-Changing Gemstone: Alexandrite
Alexandrite, a variety of chrysoberyl, is famous for its remarkable color change. In daylight, it appears green, but under incandescent light, it shifts to red. This phenomenon is due to its complex crystal structure and trace elements.
Emeralds: Inclusions and Clarity
Unlike diamonds, emeralds are prized for their inclusions, often called 'jardin' or garden. These inclusions can enhance the gem's beauty and uniqueness, making each emerald distinct. Perfectly clear emeralds are extremely rare and valuable.
Opals: Play-of-Color Phenomenon
Opals exhibit a unique 'play-of-color,' a shifting rainbow-like display. This occurs due to the diffraction of light within its silica spheres. The size and arrangement of these spheres determine the intensity and pattern of the colors.
Diamonds in Space
Scientists have discovered that some stars are composed largely of diamond. These 'diamond stars' are remnants of dead stars, crystallized carbon under intense pressure.
