Comparison of different diamond sizes in diamond painting: Selection tips for different patterns
Anyone who has done diamond painting knows that the size of the diamond directly determines the fineness and brilliance of the image. However, beginners are often confused by the various types of diamonds available, such as 2.5mm, 2.8mm, square, round, and AB diamonds—which one should they choose? Which type is best for their diamond painting needs?
Don’t worry, this article will guide you through a comprehensive understanding of the characteristics of different diamonds for diamond painting, covering aspects such as particle size, shape, number of facets, and suitable patterns. It will teach you how to quickly choose the right diamond, avoid low-quality pitfalls, and make your artwork more three-dimensional and appealing.

I. Basic Knowledge of Diamond Particle Specifications in Diamond Painting
In diamond painting, the most common diamond sizes are as follows:
| type | Common sizes | Applicable Scenarios |
| Round Drill | Approximately 2.8mm in diameter | Beginner’s Guide, Soft Patterns |
| Square Drill | Approximately 2.5mm on each side | Intricate patterns, realistic works |
| Special Shape Drill | Irregular size | Decorative works, embellishment designs |
Why does such a small difference in specifications have such a big impact?
Because the smaller and denser the diamonds, the more intricate the image; however, this also increases the difficulty of operation. For example:
- 2.5 mm square diamonds can be perfectly spliced, resulting in a clearer, seamless connection.
- softer,The 2.8mm round diamond has a tiny gap, but the light refraction is softer and the sparkle is stronger.
This is why some people like the “sparkling round diamond style,” while others prefer the “pixel-level delicacy of square diamonds.”
—AII. Diamond Painting: Square Diamonds vs. Round Diamonds – A Comparison of Visual Effects and Feel
These two are the mainstream diamond painting shapes. Below, we compare their performance from four dimensions.
| Comparison items | Square Drill | Round Drill |
| splicing tightness | Seamless transitions, like pixel art | Slight gap |
| gloss | Medium to high brightness, fine and even texture | High reflectivity, more intense flickering |
| Operational difficulty | Slightly higher, needs to be aligned with the edge line. | Easier to learn and more forgiving of errors |
| Finished texture | Visually clear and well-defined | Soft and dreamy, visually lighter |
Summary and recommendations:
- with.For beginners: Round drills are recommended, as they are easier to work with;
- style, chooseFor those seeking precision or a realistic style: choose a square drill.
- To achieve a three-dimensional glossy effect, you can try a mixed approach (square diamonds + round diamonds).
III. Differences in the “painting style” of diamonds of different sizes
used in diamond painting directly determine the refinement and brilliance of the image. Diamonds from different brands typically have between 13 and 26 facets.
More facets result in stronger reflections; more precise cut angles produce a shinier image.
3.1 Small particles (2.3–2.5 mm)
- Features: High pixel density, detailed image;
- Suitable patterns: portraits, animal fur, architectural details;
- Advantages: High resolution of the finished product;
- Disadvantages: It takes longer and requires a high level of eyesight and patience.
3.2 Medium particle size (2.6–2.8 mm)
- Features: Balances clarity and ease of use;
- ;Suitable patterns: landscapes, flowers, abstract paintings (diamond painting) ;
- Advantages: Balances image quality and speed;
- Disadvantage: Some details are slightly blurry.
3.3 Large particles (3.0mm and above)
- Features: Stronger flash and more pronounced layering;
- Suitable patterns: decorative paintings, simple graphics;
- Advantages: Easy to install;
- Disadvantages: Not suitable for high-resolution images; the finished product has a grainy appearance.
IV. Diamond painting AB diamonds and special diamonds: taking your artwork to new heights of brilliance.
In addition to regular diamonds, many diamond painters like to use AB diamonds (Aurora Borealis) or special drills to enhance the local light effect.
4.1 AB Diamond (Aurora Diamond)
- Surface coating: Features a rainbow reflective layer;
- Visual effects: Sparkling like the aurora borealis;
- Suitable locations: sky, petals, jewelry, highlight areas;
- Note: AB diamonds should not cover the entire painting, as this will result in visual clutter.
4.2 Special Shape Drills
- Shapes: teardrop, star, oval, etc.;
- Uses: decoration, embellishment, or targeted enhancement;
- Recommendation: Use only in key areas of the design to avoid overshadowing the main design element.
V. How to choose the appropriate diamond size based on the pattern?
5.1 Large-area background image
- Recommendation: Round diamond (2.8mm)
- Reason: Fast drilling speed, stronger flash surface;
- -styleExamples: Night sky, abstract background, dreamlike style artwork.
5.2 Portraits of People and Animals
- Recommendation: Square diamond (2.5mm)
- Reason: The edges are clearer and the layers are more distinct;
- Examples: pet portraits, close-ups of human faces.
5.3 Lines and Geometric Works
- Recommendation: Small square diamond;
- Reason: More precise lines, avoiding blurry edges;
- Examples: Geometric color mosaic paintings, pixel art works.
5.4 Unique creative or mixed styles
- Recommendation: AB diamond + square diamond combination;
- Reason: To make key areas stand out and create visual contrast;
- Examples: the center of a flower, the light source, and jewelry details.
VI. Hidden Techniques for Judging Diamond Quality
Regardless of specifications, the quality of the diamond determines the final look of a diamond painting. When purchasing, pay attention to the following points:
- Uniformity of cut surfaces: The more uniform the cut surface, the more beautiful the reflection;
- Color consistency: To avoid uneven brightness between different batches of diamonds;
- brightness.Material: Resin rhinestones are lightweight but have weak reflectivity, while acrylic rhinestones have higher brightness;
- Anti-static packaging: reduces the attraction of diamonds to each other;
- Quantity allowance: Premium brands will provide an extra 5-10% of spare diamonds.
VII. Summary: Different specifications determine different styles
| Creative goals | Recommended diamond type | Recommended specifications |
| Introductory Experience | Round diamond | 2.8 mm |
| Realistic and detailed | Square drill | 2.5 mm |
| decorative embellishments | AB diamonds / Special diamonds | Free mix and match |
Regardless of which specification you choose, remember one principle:
The perfect diamond is the one that matches the design.
Square diamonds create a sharp image, round diamonds soften the light, small diamonds bring a delicate feel, and large diamonds create a three-dimensional effect. Choosing the right diamond based on the characteristics of your design will allow your diamond painting to achieve the ideal balance of light and shadow.
