I really like that you left in the parts that didn’t work out, we can learn so much from that as well. Thanks for making such an easily understandable video.
Somewhere floating around you can find a theoretical specific gravity accuracy chart which you might find useful as well. I have a video idea for you if you're brave enough. What is the specific gravity of your orange cat vs the grey cat?
Hi, I'm new to this, but I have watched a few videos about specific gravity of gems and the formula in them was: (Weight in Air) Divided by (Weight in Air - weight in water) . So your large purple would be (1.277) divided by (1.277 - 0.484) = (1.277) divided by (0.793 ) = SG 1.61. Am I misunderstanding something in either videos? Cheers for the great work.
Old school...weight of dry rock ÷ the Volume... specific gravity a measure of absolute density....the water is to measure the volume ...( How much air is displaced)....i think the specific gravity of water =. One...1...so it's assumed .
What if the specific gravity is .05 higher than the specific gravity of a stone? eg, blue topaz per GIA is 3.53, in general, I'm seeing online that says 3.5 to 3.57. Mine is pulling up around 3.58. Any advice or info would be appreciated
The range is more correct. Looks like GIA reported a single SI value for...simplicity? So your measurement is just 0.01 higher, which for home units is really within uncertainty I think (I give mine plus or minus 0.03).
The bloopers 😂😂😂

Omg I’m going to learn so much in this series!

I think the addition of all my blood to the water would throw off that calculation!

Super video sir
hey, why do most scales use water thats not weighted on the scale?
