A rechargeable battery is also included with each scale, so you can use them without worrying about running out of power.

As you can see, both scales have a lot of features in common. So, what are the key differences between them? Let’s now dig into that.

Acaia Lunar vs Pearl: Key Differences

Same manufacturer, but different. 

Although the Acaia Lunar and Pearl scales share many features and are manufactured by the same company,  there are some key differences that set them apart.

MaterialsAluminum, AcrylicPolycarbonate
PriceMore affordableExpensive

Let’s look at these more closely. 


The first difference you’ll notice is in their design.

The Lunar has a simpler and more straightforward design. It comes in 3 colors: black, white, and silver.

On the other hand, the Pearl has a more luxurious and high-end look. It has a glossy finish and comes in 2 colors: black and white.

Overall, the Lunar’s more simplistic design makes it less intrusive and better suited for small spaces.

In contrast, the Pearl’s more luxurious look makes it a great addition to any coffee lover’s kitchen countertop.

Ease of Use

The second difference is in their ease of use. The Lunar has a more user-friendly interface, while Pearl’s interface is more complex.

Because of its more user-friendly interface, the Lunar is an excellent choice for those new to using coffee measuring tools or those who want a scale that is easy to use.

Ease of Use

The Pearl’s more complex interface is better suited for those more experienced with using scales or those who want more control over their brewing.


Another key difference between these two scales is their size.

The Lunar is slightly smaller than the Pearl, making it more portable and easier to store. It has a width of 105 mm, length of 105 mm, and height of 15 mm.

This can be helpful if you’re tight on space or plan to travel with your scale. Its size also fits perfectly inside the espresso machine drip trays.

However, keep in mind that the smaller size of the Lunar may make it more difficult to weigh larger brewing coffee vessels.

The Pearl’s larger size makes it easier to use, as there is more space on the platform to place your coffee mug or carafe.

However, because of its size, it can’t fit in an espresso drip tray. It has a width of 160 mm, length of 160 mm, and height of 32 mm.


When it comes to materials, these two scales are also different. 

The Lunar is made of aluminum and acrylic. These materials are designed for durability and ease of cleaning.

The Pearl is made of polycarbonate, which is more fragile but provides better heat resistance.

While both scales are made of high-quality materials, the Lunar’s aluminum and acrylic construction make it much more durable.

So, if you’re looking for a scale that can withstand heavy use, the Lunar is a great option.

However, if you’re looking for a scale that can better resist heat damage, the Pearl is a better choice.


The final key difference is in their price. The Lunar is Acaia’s more affordable option, while the Pearl is their higher-end model.

The Lunar’s lower price makes it an excellent choice for those who are on a budget, while Pearl’s higher price is worth it for those who want the best possible brewing coffee experience.
