Agate has been used for jewelry, furniture and decorative ornaments. Throughout history, they have been valued as stones of impressive beauty and charm. But seldom people recognize unpolished agate on a lake or in a freshly plowed field. Here we will talk about identifying unpolished agates.
If you find a stone with translucence, it may be an unpolished agate. In other words, if the stone has been broken and you can see telltale traces of quartz like mineral along with the red, brown and orange color that comes with many types of agate, there is a good chance that you have an unpolished agate.
Next step is to measure the stone in size and weight. In most cases, the average agate is less than 3 inches in diameter. As for weight, most agate pebbles is heavier than they look because they have dense composition. If you have no idea about this point, you can compare the agate stone with other stones.
There may be some pitting on the surface of the rough agate stone. Agates can be formed in igneous rock, and they can also be surrounded by softer rock that has since eroded away.
