VINTAGE ESTATE 14K GOLD GENUINE NATURAL ROUND PRONG SET DIAMOND EARRINGS DESIGNER SIGNED ED. The name'diamond' was taken from the Greek word,'adamas', meaning'invincible', a sheer testament to its remarkable and superior hardness. The superlative physical qualities of diamond are credited to the strong covalent tetrahedral bonding between its transparent crystals.Each individual carbon atom is connected to four other carbon atoms, all of which are very closely packed. This formation yields a remarkably strong three-dimensional cubic structure. Diamond's cubic crystal pattern is also completely symmetrical, which allows it to refract light in all directions at the same velocity (singly refractive).
