Some crochet patterns catch your eye because of their colors, while others stand out because of the stitches themselves. This crochet diamond pattern does a little of both. Its clean lines and geometric shape give it a lovely finished look, making it a wonderful option for blankets, shawls, scarves, and other handmade projects.
What I particularly like about diamond motifs is how much you can do with such a simple shape. A single diamond can make a pretty decorative detail, but join several together and you can create something much more eye-catching. Play with different yarn colors, arrange the motifs in alternating shades, or keep everything in one color for a more subtle, classic look.
You don’t need a complicated stitch combination to get this effect, either. This design uses treble crochet stitches and chain spaces to build the diamond shape. Once you understand how the stitches are arranged and where the increases go, you’ll have a useful motif that you can adapt to all kinds of projects.
Whether you’re looking for inspiration for your next blanket or simply want to try a new crochet technique, this diamond pattern is worth adding to your collection.
Crochet Diamond Pattern Details
This pattern includes instructions for three variations: a full diamond, a narrow half diamond, and a wide half diamond. Having these different shapes available makes it easier to fit the design into a larger project, especially when you’re working around the edges of a blanket or arranging motifs into a particular layout.

1. Full Crochet Diamond
The full diamond is the main motif in this pattern. It creates a symmetrical shape that works beautifully on its own or as part of a larger design.
Center Piece
Start with a magic ring. If you prefer, chain 4 and join the first and last chains with a slip stitch to make a small ring.

Work the initial groups of treble crochet stitches into the center, separating the groups with chain spaces at the corners. These chain spaces form the points of the diamond and provide room for the increases as the motif grows.
Follow the full diamond diagram for the exact placement of the stitches.
Round 1
Work additional groups of treble crochet stitches into the designated corner chain spaces, following the diagram. These increases help the motif expand while maintaining its diamond shape.
As you continue around the motif, pay attention to the corner spaces and keep the stitch groups arranged consistently. This will help the diamond stay balanced rather than becoming uneven on one side.
Continue following the diagram for each additional round until the diamond reaches your desired size.
Helpful tip: If you’re planning to join several diamonds together, try to keep your tension consistent. Making a small test motif first can help you check the finished size before starting a larger project.
2. Narrow Half Diamond
The narrow half diamond is useful when you need a smaller triangular section instead of a complete motif. It can be particularly handy along the edges of a blanket or when fitting diamond shapes into a specific layout.
Center Piece
Begin with the same basic approach as the full diamond, but work only the portion shown in the narrow half diamond diagram.
