I think you’re starting to get interested in diamond painting. The first thing I want to say is that painting diamonds is indeed a fun thing to do. It’s a great thing to do when you’re relaxing. And you can be a good painter while relaxing. When you complete each diamond painting, it brings you satisfaction with it. Are you hesitant to choose square or round diamonds now? Let me help you with that.
Difference Between Square Round Diamond
The difference between a square and a round diamond is the different shapes and different cutting surfaces. We all know that diamonds reflect light in different ways because of their different cuts. However, whether you use square or round diamonds for your diamond paintings, they all have a unique sparkle effect. No matter which diamond you choose, the grid of patterns on the canvas will match the shape of your diamond.
Better Pick Up

Because the applicator is a hollow, round stick, the round diamond is picked up more easily and quickly. So paintings made with round diamonds are completed more quickly. I suggest that beginners can try round diamonds first.
Paste

Round diamonds are not only easier to pick up, but they are also easier to paste to the canvas. Because round diamonds are the same at every angle. But the four sides of a square diamond must be perfectly aligned with each square on the canvas. So, please be more careful when pasting square diamonds.
Gaps

If you want to make the most perfect diamond painting, then you should choose square diamonds. Because there are no gaps left between each square diamond, unless you’re doing it on purpose. Another advantage of having no gaps is that all the diamonds fit together very neatly. But round diamonds can have crooked rows or columns because of gaps. It’s the square diamonds that won’t make you regret it if you’re making larger canvases.
Redraw
While a diamond ring made with a square diamond is more perfect, it doesn’t allow you to make mistakes in the process. Even if you only paste one square diamond wrongly or crookedly, then it will definitely affect all the diamonds that are pasted behind it. So you want to make sure each square diamond is in the right place. But round diamonds allow you to make mistakes. This is because there are naturally some small empty spaces around each round diamond. This means that your small mistakes can be easily corrected.
Overall. Round diamonds are undoubtedly the best choice for beginners. And the square diamond is the choice of the painter who seeks the perfect art. If you don’t have enough time to make a diamond painting, then I would also recommend going for round diamonds. Well, the above is my advice. These suggestions are just a few references, and ultimately it’s up to you to decide.
