Take a container with a rather precise scale and measure it. Place the ring inside and measure it again. The amount the water goes up is the volume of the ring.
Or you could fill a container to the brim with water, with a collecting dish underneath. Put the ring in the container, which would cause some of the water to overflow. The volume of water that left the container is the volume of the ring.
Or you could take a clay mold and make a mold of the ring, fill that with water and measure how much water it takes to fill the 3D mold.
To measure a curtain ring, you would typically measure the diameter of the inner circle on the ring. This measurement will help you determine the size of the curtain rod or pole that the ring will fit onto.

You would need to measure the finger for ring size.
There is a very specific equation for the calculation of the volume of an O-ring. it is: Gland Fill % = [(O-ring Volume) / (Groove Volume)] x 100%.
Measure the gold, take the volume of the gold, then divide mass over volume to give you the density of gold if it was the same as gold density then it is right other wise that ring is doggy
Drop it into a container half full of water and measure the amount of milliliters that rise and then turn the difference of the first and second capacities into cm3.[TIP: 1mL=1cm3 ]
I would use a ruler (metric) but careful to only measure the inside. You could also wet the beaker and place it on a piece of paper (rim down). This will leave a wet ring that you can measure. But be sure only to measure the dry inner part of the ring.
A quick way would be to see how much water it would displace. That would give you its volume. Weigh the ring and divide that by the volume of water the ring displaces (because the ring displaces a volume of water equal to its own volume). Use or convert to grams and milliliters, which are equal to cubic centimeters (or cc's). By dividing the ring's weight (its mass) by its volume, and then getting the answer in grams per one cc, you can compare your results with the density of pure gold. The density of pure gold is about 19.8 grams per cc, and with that information, you can make an educated guess as to whether or not the ring is pure gold.
You go beside the ring steps and press A.
