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

8.9 Multi-Purpose

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.

Pros
  • Can hot blend.
  • Easy to clean more liquid-like smoothies from jar.
  • Can produce bar-quality ice in less than a minute.
  • Large jar capacity.
Cons
  • Difficult to clean sticky, oily food from jar.
  • Has a hard time processing fibrous food.
9.0 Smoothies (Single Serving)

The KitchenAid Diamond Blender is alright for smoothies and protein shakes. It struggles to process fibrous fruits and veggies like kale, resulting in a leafy, foamy smoothie. On the upside, this well-built blender is dishwasher-safe, making it easier to clean liquidy foods like smoothies.

Pros
  • Easy to clean more liquid-like smoothies from jar.
  • Can produce bar-quality ice in less than a minute.
  • Large jar capacity.
Cons
  • Has a hard time processing fibrous food.
  • Produces a foamy, grainy smoothie.
8.9 Smoothies (Multiple Servings)

Pros
  • Large jar capacity.
Cons
8.6 Ice Crushing

The KitchenAid Diamond Blender is great for crushing ice. This well-built blender can produce bar-quality ice in less than a minute, which is great for cool cocktails on a hot day.

Pros
  • Can produce bar-quality ice in less than a minute.
  • Large jar capacity.
Cons
9.2 Soups

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.

Pros
  • Can hot blend.
  • Easy to clean more liquid-like smoothies from jar.
  • Large jar capacity.
Cons
  • Has a hard time processing fibrous food.
8.7 Professional Use

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.

Pros
  • Easily crushes harder food like nuts into a smooth consistency.
  • Can produce bar-quality ice in less than a minute.
  • Large jar capacity.
Cons
  • Difficult to clean sticky, oily food from jar.
  • Has a hard time processing fibrous food.

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. Although it only comes with one jar, it can hold a lot of liquid. It can produce smooth almond butter and bar-quality ice in a short amount of time. However, it doesn't offer many extra features and doesn't have a timer.

KitchenAid K400

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. 

Vitamix Explorian E310

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. 

KitchenAid K150

The KitchenAid Diamond and the KitchenAid K150 are similarly performing full-size blenders. The Diamond comes in a variety of colors, its jar is larger, and it produces almond butter with better consistency in less time. However, the K150 feels better-built and is easier to clean.

Breville The Q

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.

NutriBullet Smart Touch Blender Combo

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.

Vitamix 5200

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.

Ninja Blender Duo with Auto-iQ BL642

The Ninja Blender Duo with Auto-iQ BL642 is better than the KitchenAid Diamond. The Ninja has a much better build quality and makes significantly better-blended smoothies. It makes more spreadable almond butter, crushed ice with a better texture, and it's much easier to clean by hand. It also comes with three differently-sized personal jars in addition to its 72-ounce main pitcher. Nevertheless, you can use the KitchenAid Diamond to blend hot ingredients, so it's better for making soups.

Ninja Foodi Cold & Hot Blender

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.

Oster Pro 1200

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 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.

Build Quality

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 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.

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.

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.

Ease Of Use
Cleaning

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.
