The Rubies and Diamonds Hat Pattern

Updated January 14, 2019
The Rubies and Diamonds Hat Pattern
The Rubies and Diamonds Hat Pattern

I designed this simple hat pattern because I wanted something a little more interesting than just a plain old stockinette hat. But I also didn't want to learn some overly complicated technique, like brioche.

This pattern is versatile, relaxing (because it's still mostly stockinette), and quick to work because it uses warm, bulky yarn. The diamond shape is made over 21 rows of carefully placed purl bumps, so you can get a visually interesting motif without having to do something more complicated like fair isle or juggle more than one color of yarn.

The diamonds of purl bumps continue upwards into six peaks around the hat. The peaks of the motif blend in seamlessly into the decreasing in the crown of the hat, which is really the only tricky part of this pattern.

  • Stitch marker


Ribbing and Motif

CO 60 sts + 1 for the invisible join
Rnds 1-7: (K2, p2), repeat ( ) all the way round
Rnds 8-10: K all sts
Rnds 11-37: Follow the pattern in the chart below


Move sts onto 4 DPNs evenly (15 sts per needle)
Rnd 38: (K4, cdd, k3), repeat ( ) to end of rnd
Note: See below for how to work a "cdd" or centered double decrease.
Rnds 39 and 40: K all sts
Rnd 41: (K3, cdd, k2), repeat ( ) to end of rnd 
Rnds 42 and 43: K all sts
Rnd 44: (K2, cdd, k1), repeat ( ) to end of rnd 
Rnd 45: K all sts
Note: At this point, you should notice that the columns of centered double decreasing line up with the peaks of the purl motif.
Rnd 46: (K1, cdd), repeat ( ) to end of rnd
Note: You might have to move stitches between DPNs in order to more easily complete the decreases.
Rnd 47: You should have a total of 8 sts across all of your DPNs. Cut a tail of yarn and thread it through these stitches to finish your hat. Pull the tail tightly and weave into the wrong side of the hat.

How to Work a Centered Double Decrease:

  1. Slip two stitches together knitwise
  2. Knit 1
  3. Pass both of the slipped stitches over the knitted stitch

This was an easy quick knit and the final product looks great. I did use a 16" circular needle for most of the hat. I also added a faux fur pompom.

carol Is. It. absolutely necessary to change to double pointed needles? Can I just continue on the circular needles? Thank you Marthese

After the chart is completed (60 sts), the next instruction is to change to DPN's putting 15 stitches on each needle. This only totals 45 sts. Should it not be 20 sts per needle? Could you please spell out in more detail Rnds 45-48 please.

Hi carolfc, in this pattern, the stitches are divided amongst four double pointed needles, not three, so you would put 15 stitches on each for a total of 60. However, you are more than welcome to put 20 each on three needles instead! As for rounds 45-48, you are simply knitting in stockinette stitch while performing CDD decreases where they align with the previous decreases. Let us know if you have any trouble with this! -Editors of AllFreeKnitting

Hi Carol! We have updated this pattern to spell out the decreasing a little more clearly. Thanks for you feedback! -Editors of AllFreeKnitting

Are the odd rows of the chart read right to left and the even ones read left to right?

Hi carolfc, this hat is knit in the round and therefore all the rounds are on the right side. You should read the chart from right to left for every row of the chart. We hope this helps! Happy knitting! -Editors of AllFreeKnitting

Without the key, the chart is pretty useless.

Hi Lisa! This chart follows the CYC standard yarn chart symbols, which means in this case that the empty fields are knit and the fields with a dash are purled. We hope this helps! Happy knitting! -Editors of AllFreeKnitting
