Gemstone Carat Weight Estimation Calculator

Thus a .10 carat stone can be called either 10 points, or 1/10 of a carat. Small stones like .05, and .10ct are most often referred to by point designations. The spelling of karat with a "K" is a measure of the purity of a gold alloy, as opposed to stones. A one carat round diamond of average proportions is approximately 6.5mm in diameter.

Gold in Quartz - How to Calculate the Gold Content

To explain that in other words, the specific gravity of gold is 19.3 which means the weight of gold is 19.3 times that of an equivalent volume of water (at 4 degrees C). If water weight is 1 gram per ml then Gold at an SG of 19.3 is 19.3 times as dense as water or 19.3 grams

Specific gravity test for gold - Goldbay

The simplest way to test specific gravity is weigh the quartz gold specimen in "air" and multiply the weight by 1.9. Then weigh the quartz gold specimen fully submerged in "distilled water" and multiply that weight by 3.1. Minus the wet figure from the dry figure and you will get a fairly accurate specific gravity for that specimen!!
