text: how can i find out the value of my moldavite and  or sell?   honestly, i don't know about the process of grading tektites, like moldavite. you would need to take it to a gemologist for appraisal. you could take your chances and put it up for sale at an online auction...the bids will tell you how much it's worth. however, if you don't want to risk selling it for less than you think it's worth, you might do an online search for people who sell moldavite. contact them and see if they'd like to buy your moldavite and add it to their product lineup. you'll need to know carat size and other information. there are plenty of "rockhounds" out there who might be willing to offer some advice; however, your best bet might be an appraisal by a licensed gemologist.
