The Heavenly Metals Store sells a variety of 1" metal cubes, all of great quality, and each with information on the element. The tungsten cube is the heaviest, with a density of 19.3 g/cc.

4.0 out of 5 stars Very Nice, Even With Tiny Marks On It
Reviewed in the United States on February 23, 2024
For some reason I cannot give separate reviews for the two cubes I purchased.

Mg - There are relatively small machining marks on the cube, unfortunately one is on the front and goes thru some of the print. Corners are sharp and could be dangerous, but I knew that going in, cleaning that up would be a more expensive cube. Overall - I am quite pleased, got this with a tungsten cube for comparison.

W - This cube appears to be perfect, no machining marks. Very pleased, would recommend.

It is 'trippy' to hold the Mg cube for some time, roll it around in the hands. Then set it down and pick up W - whoa!

5.0 out of 5 stars Must have for your element block collection.
Reviewed in the United States on February 16, 2024
I really enjoy my element blocks, makes for a great science and density project. The Magnesium and Zinc cubes from Heavenly Metals are the only ones I've found that actually have the correct elemental information on them, many others have wrong numbers or wrong temperatures. Laser etching is clean and legible. I wish the corners had a slight rounding to them (that's easy enough to fix with some high grit emory cloth) but you know you're getting all 1" of the element. my block weighed in at 29 grams so It is exceptionally close to the weight it supposed to be (28.51 grams). Enjoy.

We are happy to report that our new replacement Tungsten cube has the correct information printed on it. The seller was very gracious and responsive in replacing the original one that had been part of an accidentally misprinted batch. Thank you ‘Heavenly Metals’!

3.0 out of 5 stars Nerdy and nice but the packaging is very flimsy
Reviewed in the United States on July 1, 2024
My son loved getting a Tungsten cube but for the money I would have expected that it comes in a nice cloth sleeve or some sort of decorative box but it came in a plastic bag with damaged cardboard box. Looked very cheap and appeared second hand product.
