Zircon Crystals trap Uranium Atoms in its crystal structure and naturally repels Lead. Once the crystal structure is formed, nothing is able to get out. Over time the isotopes of Uranium starts to transmutate into other elements in what is referred to as a decay chain. An Uranium Atom first transmutates to a Thorium Atom which takes a few billion years. Thorium is far more unstable, and in less than a month it turns into Protactinium. Within a minute Protactinium atoms transmute again, and so on.

Zircon is a zirconium silicate mineral with a chemical composition of ZrSiO4. It is common at some point of the world as a minor constituent of igneous, metamorphic, and sedimentary rocks. It is a popular gemstone that has been used for almost years.
Of all the isotopic dating methods in use today, the uranium-lead method is the oldest and, when done carefully, the most reliable. Unlike any other method, uranium-lead has a natural cross-check built into it that shows when nature has tampered with the evidence. Uranium comes in two common isotopes with atomic weights of and we'll call them U and U. Both are unstable and radioactive, shedding nuclear particles in a cascade that doesn't stop until they become lead Pb. The two cascades are different—U becomes Pb and U becomes Pb.
