🌟 Fluorescência – Parte 1 Você sabia que algumas gemas brilham sob luz ultravioleta? ✨ Neste vídeo, explico o que é a fluorescência e mostro como um rubi verdadeiro reage sob a luz negra, revelando um brilho vermelho intenso que parece vir de dentro da pedra. Esse efeito não é só bonito — é também usado na identificação de gemas autênticas. #Fluorescencia #Rubi #PedrasPreciosas #Joias #curiosidades
