Here are several nephrite bangles that I collected. The first one is my favorite white nephrite from Hetian area, Xinjiang, China. The other three are Russian nephrite.

Here are more nephrite bangles from Qinghai area, China. There are nephrite with various color. The price for nephrite from this are are considerably lower than those from Xinjiang area or Russia.

Beautiful collection Matsalice! - thank you for sharing. I can see why the first bangle in your first post is your favourite. I love all the chubby princesses
[emoji6]Thank you. I love its size and its very white color.Beautiful collection Matsalice! - thank you for sharing. I can see why the first bangle in your first post is your favourite. I love all the chubby princesses
My new D shaped princess bangle arrived today!
...and got immediately stacked with some beads I was wearing today. I especially love the dark green spots!
I am amazed at how comfortable a D bangle is after wearing a round one. Though I have heard that there are better health benefits to wearing a round bangle.
Opinions? Do you prefer to wear a round or D shaped bangle?
These are some more beads I was wearing.

Hi ladies! I haven’t been on here in ages. I got a new jade bangle and am having a hard time calculating the density because of different calculations. In one way it is ok (just dividing the 2), but in a different calculations where you divide by volume (subtracting the 2 weights) it doesn’t seem to be jade.
Can you help? Which way is the correct way? It weighs 36 grams in air and is 11 grams suspended in water. Thank you!

TL : DR
It should be 36/11 = 3.27
The long story.
I am not an expert on this and my knowledge is based on my looking online and scratching my head about how to calculate density at home to distinguish jadeite / nephrite from other suspect materials, but maybe you will find what I have found out useful.
It should be dry weight divided by weight suspended in water. (This calculates specific gravity, not density but usually specific gravity is quoted for jadeite to be 3.33 - 3.34 so that fraction is usually what you want.) The suspended jade on a bent paper clip or some small thing like that should be covered completely by water and not touch the sides or the bottom of the bucket and the temperature of the water should be 4 degrees C and there are a bunch of other technical details why and why this works to calculate specific gravity and how it relates to density, but they don't matter much if the scale you are using is no more accurate than a regular kitchen scale.
Here is the link: http://www.johnbetts-fineminerals.com/jhbnyc/articles/specific_gravity.htm I used to do the measuring and calculation of specific gravity using dry weight and weight suspended in water as opposed to the other formula with the subtraction.
Following the directions there, with a food scale that is supposed to measure in increments of 0.1g +/_0.3g, I can only get the SG of my real jadeite to only be like 3.1 to 3.2-something. Depending on color, most of the materials that are used to imitate jadeite or nephrite are quite a bit off from this number so this level of accuracy may be enough for your purposes. Here is a table from this article: https://www.gia.edu/doc/The-Jade-Enigma.pdf to get an idea of what to expect from the specific gravity of substitute materials.
None of this will help distinguish treated jadeite from Type A, unfortunately.
I hope this helps. Sorry for the long post.

Thank you so much jadeitebear! I love your new beautiful pieces!
It doesn’t light up under a black light, feels cold to the touch, but it definitely doesn’t feel heavy for its size, but if it’s doing ok on the density test, it’s must be ok, hopefully. I used a kitchen food scale, so I’m assuming it’s somewhat inaccurate. I suspended it using dental floss and with paper clips, and got the same weight both times
Here’s the bangle.
This is my 2nd jade bracelet. I lost my first one somehow and have looked for years. I finally gave up and got a new one !
