How to distinguish the quality of advertising balloon Mosan diamond ring, can the naked eye see the quality of Mosan diamond?

Distinguishing grindstone from diamond;

1, specific gravity: Mosan stone is lighter than diamond, that is, their specific gravity is different. The specific gravity of diamond is 3.52, while the specific gravity of mosan stone is only 3.22. For non-mosaic materials, it is easy to distinguish them with methyl iodide specific gravity liquid (specific gravity 3.32).

2. Hardness: The hardness of the grindstone is less than that of the diamond, so the marking test on the surface of the grindstone with a diamond hardness tester will leave scratches, but the marking instrument will not leave scratches on the surface of the diamond.

3. Conductivity: According to GIA's report, 80% of Mosanite is an electrical conductor (only blue and blue-gray IIb diamonds in natural diamonds have conductivity). Common white/light yellow diamonds are not conductive, so diamonds can be distinguished from mosan by conductivity meter or mosan instrument.

4. Refractive index: Mo Sanshi's refractive index is different from that of diamond, and its reflective characteristics are also different from that of diamond, which can be distinguished by experienced diamond appraisers; In addition, Mosang stone has birefringence, and it is not difficult to see the ghost of Mosang stone ridge and bottom tip by careful observation. At this time, changing the observation angle, ghosts will still appear.

5. Biaxial optical characteristics: Due to the biaxial optical characteristics of kyanite, the observation of its ghost characteristics depends on the observation angle. When viewed from the main surface of the countertop, the ghost image is obvious. Although the ghosting will be reduced when the mesa is perpendicular to the C axis of Mosanite crystal axis, the reflected ghosting of mesa and crown can still be seen when focusing on the bottom tip, which is completely different from the crown reflection of single refraction diamond.

6. Polishing lines: The waist polishing lines of Mosang stone are parallel to each other, which is completely different from diamonds. Moreover, due to the differences in different directions, the polishing direction should be constantly adjusted during the polishing process of diamonds, while Mosang stone can be polished in the same direction. This is especially evident between adjacent facets.

7. Cutting: Most of the edges of the cut Mosang stone are blunt, which is completely different from the sharp-edged diamond.

8. Inclusions: Inclusions in diamonds are different from those in mosangshi. There are some inclusions in all identified mosanites, which are arranged in parallel needles. Thin parallel reflection lines can be seen in some mosang stones.

9. Color: Mosangshi introduced DF grade color synchronized with diamonds on 20 15, which is difficult to distinguish.
