Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as Figure 4 , is a simplified structural diagram of the measuring instrument of the present invention, which is a measuring instrument that eliminates the effect of size factors on the accuracy of diamond color, including an integrating sphere 1 with a detection device 2, a sample positioning device 3 installed on the integrating sphere 1 body, and a sample positioning device Inside is the sample positioning groove 4 carrying diamonds.

[0022] The light source is injected into the integrating sphere 1 of the present invention to completely cover the sample positioning device 3, so that the entire sample positioning device 3 is within the range of the light source, and two test sample diamonds A1 and A2 with different volumes are respectively placed on the sample positioning device 3 The sample positioning groove provided inside, the sample positioning gr...

Abstract

The invention discloses a measurement instrument for removing influence of a size factor on color accuracy of a diamond. The measurement instrument comprises an integration ball with detecting equipment. A sample positioning device is mounted on an integration ball main body; and a sample positioning groove for bearing the diamond is arranged in the sample positioning device. According to the measurement instrument provided by the invention, the diamond color measurement is carried out by using an improved integration ball of an optical instrument, so that the problem of influencing the measurement accuracy by color difference, caused by different diamond sizes and different generated light ranges in the diamond color measurement, can be solved.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a measuring instrument for diamond properties, in particular to a measuring instrument for eliminating the influence of size factors on the accuracy of diamond color. Background technique [0002] Diamond identification has 4C standards, in which the color (color) is generally graded from colorless to light yellow. The identification standard is an international general standard, mainly based on the standards of CIBJO (International Jewelry Federation) and GIA (Gemological Institute of America) , the standards of master stones range from colorless D grades to yellow Z grades. [0003] The mechanism of diamond color formation is a rather complex issue that has been the focus of many research institutions for many years. In an ideal state, diamonds are colorless because they are complete equiaxed crystals and have no selective absorption in the visible range. However, naturally occurring...
