Density is mass/volume. Specific gravity is density of the item under test/density of water. Density of water is near enough 1g/cm³ so for our purposes density and specific gravity are near enough to be called the same.

The highest density possible for an Ark is something like 2.65 or thereabouts - this is the density of pure void-free quartz/SiO2 - what Arks are made of almost 100%. I would like to hear what method was used to arrive at the figures given for the OP's stones. Measuring with a ruler and cheap postal scale will not give accurate numbers.

Just calculated yesterday, my Trans Ark was around 2.80 so are you sure Eric? Iam sure i calculated correct....

I also dont think you need a hypercalculated ruler, if youre correct on mm that should do it.

I would vote for surgical Black Ark, not too many other possibilities around...

Thanks for all the replies, guys!

One post in. Welcome to SRP. Please introduce yourself further.

Is there a specific place to do that? I've got a little problem using the forum, i keep getting "Bad Request Your browser sent a request that this server could not understand."

Measured using a digital caliper, nine measurments taken on the large flat sides, six along the edges and two over the ends. Measurments averaged out to a tenth of a millimeter.
Used a relatively cheap digital scale. It has always been within 1% of the scale in my local post office, those have to be calibrated regularly so it should be pretty accurate.
2,80 can absolutely be a little off, there's always SOME error when measuring, but it should be quite close to accurate.
