Comment: Peridot, in any size, is a so called 'idiochromatic' gem, meaning it is not colored by impurities in an otherwise colorless mineral, such as sapphire or beryl. The latter, called polychromatic gems, are found in various colors depending on which chemical imperfection earth has thrown into the mix during its long growth in the crust. Peridot, on the other hand, grew far deeper in earth's mantle and is colored only by iron, full-stop: The more and purer the iron, the better and the more vivid the green. Olivine, the non-precious mineral from which peridot presents a tiny section, occurs widely throughout the universe; the choice of word being no coincidence since the olivine is found on mars, moon, and on meteorites. Clean and durable olivine in facet-quality such as this here, or 'precious olivine', is called peridot. Like emeralds, it was first mined in what was then Lower-Egypt, millennia ago, and was compared, and probably sold as a type of emerald to the unsuspecting tourist (yes, there was a sort of tourism, even then) and to the tribal chieftains of Northern Europe. But, alas, I divert.... our new 16 carats giant of a peridot contains his fullest dose of iron, far, far removed from the pale green specimens diluting the market from China and elsewhere. This here is, together with Burma peridot, is true collector quality, the real deal not calibrated custom-jewellery. Compare to this Burmese master-gem. The oval Pakistani is over-all more included, though rarely less than eye-clean, while the big Burmese gem exhibits only one fascinating feather, his smaller colleague allows a lens-study of veils, crystals, feathers, and classic inclusions (something that has grown inside the gem). Definitely a gent's ring-size or the center of an impressive pendant. Amongst all-natural green gems, the only affordable option over ten carats. In this color quality, all green gems, demantoid, sapphire, even zircon, and let alone emerald, will tear a deeper hole into your bank account. Other than the newest e-gadget or fashion item, such a gem will not only last forever but actually increase in value over time. True, a well-picked stock will do fine, too, but then perhaps not, and you won't enjoy its beauty on a daily basis. At a mere $325 per carat unbeatable value in the market for giant all-natural green gems. Any black spots in the images are background reflections - no black inclusions. Any inclusions are visible to the unaided eye only from the back-side. All photos were shot in low daylight and indoors, yet note the gleaming luster even in the hand-shot.
