The KitchenAid 5-Speed Diamond Blender is a full-sized blender that comes in several colors to help match it with your kitchen decor. It has a unique jar that's slightly angled into a teardrop opening, which makes it easier to pour, and it can hold 60 ounces of liquid, which is quite large. It can also quickly produce smooth almond butter and bar-quality crushed ice. However, it struggles to process fibrous fruits and veggies like kale. Its jar can also be a little difficult to clean as its blade assemblies aren't removable. That said, you can put the jar with its blades and lid into your dishwasher's top rack for an easy clean.
Our Verdict
The KitchenAid Diamond Blender is good for multi-purpose use. While it has trouble processing fibrous kale, it's much better at producing smooth almond butter or bar-quality crushed ice. It's also well-built, and its jar can hold a lot of liquid. It can hot blend, which is good if you like to make soups. However, it can be difficult to clean oily or sticky food from the diamond-shaped jar.

The KitchenAid Diamond Blender is very good for soups. It has a large jar size, and it's able to hot blend, so you can put quite a bit of stewed food directly into the jar and blend it. However, it struggles a bit more in processing fibrous fruits and vegetables. As long as your soup isn't very sticky or oily, you shouldn't have too much trouble cleaning it.

The KitchenAid Diamond Blender is very good for professional use. It can easily process almonds into smooth nut butter and produce bar-quality ice in little time. However, it has a harder time breaking down fibrous fruits and veggies. It's easy to clean the jar if you made runny or liquidy foods like smoothies, but the fact that you can't remove the blade makes cleaning after something more consistent, like nut butter, more difficult. On the upside, the jar can hold a lot of liquid.

Differences Between Sizes And Variants
The KitchenAid 5-Speed Diamond Blender comes in several color variants that you can purchase to match your style. While we tested the 'Metallic Chrome' variant of this blender, we expect that other colors perform similarly. There's also an almost-identically designed model called the KitchenAid 5-Speed Blender, but it doesn't have the diamond design. Its pitcher also holds 56 ounces, and it comes with an additional jar that holds 24 ounces. However, we haven't tested this blender and don't know if it performs like the KitchenAid Diamond Blender.
If you come across another variant of the KitchenAid Diamond Blender or if your unit is different, please let us know in a discussion thread below, and we'll update the review if needed.
Compared To Other Blenders
The KitchenAid 5-Speed Diamond Blender is a full-sized blender that comes in a variety of colorful variants to better match your kitchen decor.

The Breville The Q is a better blender than the KitchenAid Diamond for most uses. The Breville is better-built, and it comes with a tamper. It makes a better smoothie, and it's much easier to clean by hand. However, the KitchenAid is better for crushing ice.
The KitchenAid K400 and the KitchenAid Diamond have different strengths. The K400 has a better build quality and makes a smoother puree with big batches of fibrous ingredients like multiple servings of kale smoothie. It makes more uniform crushed ice. On the other hand, the Diamond is much easier to use for recipes like nut butter. It's also easier to clean.
The Ninja Foodi Cold & Hot Blender and the KitchenAid Diamond have different strengths. The Ninja is better-built, has a bigger capacity, and you can use it to heat up cool ingredients. It's a better ice crusher as well. On the other hand, the KitchenAid makes a smoother blend of fibrous ingredients, so it can make a silkier smoothie or soup. It's also much easier to use for thicker mixtures like nut butter. It's also quieter when it's running. The jar and lid are dishwasher-safe and easier to clean by hand.
The KitchenAid Diamond is better for most uses than the NutriBullet Smart Touch Blender. It does a much better job of tough tasks like making nut butter and crushing ice. It's easier to clean by hand and somewhat quieter when it's running. On the other hand, the NutriΒullet comes with personal jars for single-serves, so you may prefer it if you use your blender for smoothies or protein shakes.
The Vitamix 5200 is a better full-size blender than the KitchenAid Diamond. It has a significantly better build quality and makes better nut butter, smoother blends with fibrous ingredients, and crushed ice with better consistency. It's also easier to clean.
The KitchenAid Diamond is better than the Ninja Blender Duo with Auto-iQ. The KitchenAid makes a smoother blend with fibrous ingredients, whether working with small or big batches. It's also easier to use for thick blends like nut butter, and its blade design makes it easier to clean by hand. On the other hand, the Ninja comes with at least two personal jars for single-serve smoothies in addition to its 72-ounce pitcher. It also feels better built.
The KitchenAid Diamond is better than the Oster Pro 1200. It has a much better build quality, it's quieter when running, and its main jar has a bigger capacity. The Oster comes with a 24-ounce personal jar, but the KitchenAid does a better job of processing small batches of fibrous ingredients for something like a kale smoothie.
The Vitamix Explorian E310 is a better full-size blender than the KitchenAid Diamond. The Vitamix has a significantly better build quality and has a better overall performance. It gives you more control over the blending speed. However, the KitchenAid is significantly quieter when it's running and has a bigger 60-ounce capacity.
Test Results
The KitchenAid 5-Speed Diamond Blender is a somewhat tall full-size blender. However, it doesn't take up that much room on your counter, and you can keep it out on the table or place it into a cupboard without a problem.
This blender has a good build quality. It has a sturdy base with easy-to-clean buttons. The uniquely diamond-shaped jar also feels like its made of good quality plastic. However, its design and irremovable blade assemblies make it harder to empty when your food is ready. The jar's lid also doesn't really stay in place, either. Other parts of the blender don't feel very solid such as the locking mechanism, and the buttons don't feel very responsive.
The KitchenAid 5-Speed Diamond Blender has sharp blades that are attached to the bottom of the jar. You can't remove them, but you can put them in the dishwasher. Just remember to remove the lid from the jar.
This uniquely shaped lid helps to keep food and liquid from spilling out of the jar. It uses friction to form a seal, but it doesn't really stay in place.
This blender has a cable long enough to reach a power outlet on your counter. When you're not using it, you can also store the cable away.
The KitchenAid Diamond Blender produces adequate smoothies. Although the manual doesn't specify how to make a smoothie, it says that when making thin fruit juice to use the 'Ice Crush' setting first, followed by its highest setting to blend. The resulting smoothie has a light green color and is very foamy. There's a lot of graininess as the kale isn't completely processed, and it has a thick consistency. If you want a similar blender that's much better at making smoothies, check out the KitchenAid K400 or the Breville the Q.
Update 09/24/2020: We have updated this test's score from 'N/A' to '0'.
The KitchenAid KSB1575 doesn't have another jar.
This blender produces great crushed ice. Following the manual recommendations, it's able to create bar-quality ice in less than a minute.
This blender makes excellent almond butter. On its highest setting, it can crush almonds without a problem, but some of the nuts can stick to the sides and require a bit of a push back into the mix. The almond butter it produces is smooth, a little sticky, and without almond chunks.
This blender has several preset speeds. After pressing the power button to turn the blender on, its light indicator flashes to let you know when it's ready. You can then select one of its five speeds, which run in a continuous blend mode. If you want to pulse, press the pulse button, then select one of its five preset speeds. This mode runs for as long as you hold the preset button down.
On top of its five preset speeds, this blender has a crushed ice setting. However, that's about it, and it doesn't have a self-clean program, which is more commonly found on higher-end models.
This blender is just okay to clean. While it's easy to clean more liquidy foods like smoothies or soup from the jar with a 60-second water and soap blend on high, it isn't easy to clean food like almond butter. As the jar is very narrow at the bottom, it can be hard to clean sticky food from under its blades, especially since you can't see if there's still food clinging to it. You may have to use a brush and hot water to remove the remaining food and oil. If you want a blender that's easier to clean, check out the Ninja Foodi Cold & Hot Blender or the Vitamix ONE.
