    Thank you for this nice video. It's very direct and informational and straight to the point without a bunch of nonsense first.

      @@paranorml1 Yes, I think you should, the reason being is the formula for specific gravity that I learned was dry weight divided by the difference between the dry and wet weight. Unless, of course, my geology prof was wrong. But I liked your video presentation.

    Thanks for the share! I am just learning about SG and have filled my head with a lot today! Your video helped put it all into perspective. A few years ago I purchased several hundred gemstones from someone who was buying jewelry just for the gold. I stopped in one day and for $100 he sold me all of the stones (only a small handful of very small diamonds). You would be AMAZED to know all of the gemstones I’ve found (I went back one more time before he went out of business) some worth over $10,000! A 3mm purple, color changing, oval sapphire! Now, it’s time to test them I’m a silversmith and truly enjoy making jewelry but some of these gemstones are just too special for my style of jewelry. I’m grateful for your video and the knowledge that you’ve shared with me. It will definitely help me in determining if my $200.00 (total of two trips) investment in these stones is going to be a FABULOUS investment!!!!

    You forgot to weigh the string as well, is why most are off by just a touch.

    the only bummer is I had to watch you weigh 2 dozen rocks to finally get to the point which is the division of the dry weight by the water displacement weight.

  • @scdreamers1764
    @scdreamers1764 Před 2 lety

    As already stated, the calculation is incorrect. The difference is used divided into the weight in air, not the weight in water.

  • @patriciagonzalez9341
    @patriciagonzalez9341 Před 2 lety

    Would you please answer a question? It seems nowadays specific gravity is being found by dividing air weight by water weight. Another formula is to subtract water weight from air weight and then divide. Which is most correct? Thank you.

      I'm not sure about any other home methods. To get a full scientific Specific Gravity requires special equipment and complex math equations. But the way I do it in the video is the easiest way I know of. Simple with simple equipment......

    Question. Can I use a kitchen scale for this?

    • @paranorml1
      @paranorml1  Před 2 lety

      Yes, you can use a kitchen scale. But remember that the more accurate the scale the better. It is very difficult to be accurate with a small stone, unless you have a very accurate scale.
