What is the 3EX cut of a moissanite diamond

Many people who buy moissanite diamonds may have heard others introduce 3EX moissanite diamonds, some may know that this refers to the cut of moissanite diamonds, so what is 3EX moissanite diamonds and is the 3EX cut the best?

3EX is the cut of a moissanite diamond CUT is EXCELLENT, POLISH (polish) is also EXCELLENT, SYMMETRY (symmetry) is also EXCELLENT, the combination of these three is 3EX, of course the combination of 3EX should be the perfect cut, it shows the best moissanite diamond fire.

Cut: the angle and proportion of the cut made by an experienced craftsman in the process of transforming a raw moissanite into a polished moissanite stone.

These include the table width ratio, crown height ratio, waist thickness ratio, pavilion depth ratio, base tip ratio, full depth ratio, crown angle, pavilion angle, diameter, height, etc. The grades are excellent (EX), very good (VG), fair (F) and poor (P) in descending order.

Polish: refers to the diffuse reflection of light on the uneven surface of a moissanite diamond, describing the smoothness of the surface. The polish is characterised by being located on the surface, with no visible bleed-through when viewed with a 10x magnifying glass.

Polishing is graded on a scale of EXCELLENT (EX), VERY GOOD (VG), FAIR (F) and POOR (P). A severe polish will not only greatly reduce the brilliance of a Moissanite diamond, but will also affect its clarity. The quality of the polish is mainly related to the cutting and polishing process of the Moissanite diamond and the skill and care of the cutter.

Symmetry: the horizontal symmetry of the parts of a moissanite diamond around its centre point, obtained after cutting and polishing, i.e. the arrangement of the facets and their angle to each other. As important as the ratio, it is an indicator of the second. If the cut and proportions of a Moissanite diamond are excellent, symmetry will result in a more intense sparkle and fire.

The symmetry of foreign certificates is evaluated in more detail, from highest to lowest, as follows.

1. IDEAL (ID)

2. excellent (EX)

3. very good (VG)

4. fair (F)

5. poor (P)
