Water-slipping diamonds is a commercial term in Vietnam used to refer to diamonds whose color perception is close to the boundary between two adjacent color grades on the GIA scale (e.g., between E and F), causing the stone to have a slightly warmer hue than the usual standard for that color grade. Let's explore the technical nature, identification methods, and buying experience for this type of diamond with Jemmia below.
What are Water-Slipping Diamonds?
What is Diamond Color (Nước)?
Diamond color is the term for color (Color) – one of the four standards in the GIA 4Cs system, graded alphabetically from D (colorless) to Z (yellow). The GIA color scale focuses on quantifying the absence of color in the stone. The closer a diamond is to D, the more transparent and commercially valuable it is.

What are Water-Slipping Diamonds?
Water-slipping diamonds is a term referring to diamonds with a slight deviation in color compared to the standard. However, the difference in color grade is not significant. This also means that the quality of water-slipping diamonds will not be as high as that of standard diamonds.
To understand this better, we can use the example of a water-slipping E diamond. In this case, the diamond's color grade would fall between the E and F thresholds. Therefore, its color is not quite E but is higher than F. This example can be applied to other water-slipping diamonds.
| Color Group | Color Grade Symbol | Perceptual Characteristics |
| Colorless | D – E – F | Transparent white, highest color purity |
| Near Colorless | G – H – I – J | A very slight warm hue appears when the stone is flipped |
| Faint Yellow | K – L – M | A noticeable faint yellow or brown hue |
| Very Light Yellow / Yellow | N – R / S – Z | Obvious color, not in the white diamond category |
How to Identify a Water-Slipping Diamond?
Without a color chart or a specific color grading scale for comparison, it is difficult to distinguish water-slipping diamonds. However, the most common method currently is to compare them with diamonds of standard color grades.

This method is considered easy to perform and has a relatively high accuracy. To use this method, you need to have diamonds with standard color grades and compare them directly with the diamond you want to identify. Through this comparison, you can detect the color deviation based on the difference in color. Common cases encountered are a duller color or a yellowish tint compared to standard diamonds.

Quality diamonds with clear GIA certificates of origin
However, this method does not guarantee absolute accuracy. In addition, if conditions permit, more modern equipment can be used for detailed inspection and to achieve more accurate results.
So, Should You Buy Water-Slipping Diamonds?
Although the color grade of these diamonds is not as high as other natural diamonds, overall, water-slipping diamonds still attract consumers with the following outstanding features:
Diamond Fire
Natural diamonds are inherently known as the "queen" of gemstones with their sparkling, radiant beauty. This beauty is not diminished but rather enhanced in water-slipping diamonds. When exposed to natural light, shimmering streaks of various colors will appear. This is called diamond fire, or rainbow fire.
Diamond Brilliance
One of the most sought-after characteristics of this type of diamond is its brilliance. These diamonds possess an extremely captivating and radiant brilliance. This is also one of the reasons why many people are easily mistaken between synthetic diamonds and water-slipping diamonds.

Considering the 3 Excellent Criteria
The 3 Excellent criteria include Excellent Cut, Excellent Polish, and Excellent Symmetry.
Excellent Cut
The cut is the factor that gives water-slipping diamonds their beautiful fire. Thanks to meticulous craftsmanship and the nature of this type of diamond, light refraction occurs, causing the diamond to create fire.
Excellent Polish
The polish of this type of diamond is their excellent advantage. Rated at 10 on the polishing scale. When used to create jewelry, this level of polish will be a highlight for the piece. This also helps the color of water-slipping diamonds stand out more.
Excellent Symmetry
Symmetry in a diamond affects its beauty and uniqueness. Therefore, we can see that a perfect diamond needs precise symmetry. For diamonds that are highly sought after, symmetry becomes a superior strength. Each facet and edge is arranged with absolute perfection, creating a beautiful visual effect.
