Abstract

"DESENHO DE LAPIDAçãO DE DIAMANTES QUE FORNECE UMA GRANDE QUANTIDADE DE REFLEXãO DE PERCEPçãO VISUAL PARA USO ORNAMENTAL E MéTODO DE OBSERVAçãO DO MESMO". A presente invenção refere-se a um desenho de lapidação de um diamante ornamental e um método de observação do diamante pelo qual um observador pode perceber mais beleza. O desenho de lapidação é uma lapidação brilhante redonda que compreende uma cinta, uma coroa acima da cinta e um pavilhão abaixo da cinta. Uma altura de cinta (h) é 0,026 a 0,3 vezes um raio de cinta, um ângulo de pavilhão (p) de uma faceta principal de pavilhão varia de 37,5 graus a 41 graus e um ângulo de coroa (c) de uma faceta principal de coroa está compreendida em uma faixa que atende: c>-2.8667xp+134.233 e p<1/4x{(sin.^ 1^(1/n)+sin.^ 1^(1/n.sinc))x180/<227>+180.2c}, onde n: índice de refração de um diamante, <227> : constante circular, p: ângulo de pavilhão em graus, e c: ângulo de coroa em graus. O desenho de lapidação do diamante ornamental provê a um observador uma grande quantidade de reflexão de percepção visual quando o observador olha o diamante acima de uma faceta de plató com uma linha de visão de um ângulo menor do que 20 graus com uma linha vertical no centro da faceta de plató.
