Last weekend, we visited our first rock, gem and rossil show at Cartersville, Georgia. It was an eye opener for us. They were many dealers in the expo. We have a chance to see various kind of rocks, minerals and fossils from around the world. Some rocks displayed in their natural forms while others are polished. They are both pretty. At the end, we decided to bought each other some souveniers. I choose the Ammonites and Nautilus fossils from Madagarsca and a bag of mineral specimen, mom and megan choosed a ruby and topaz from the bargen pile. Alan seem to be more interested in bigger crystal clear Quartz.
Mom and Megan let me borrow the gem stone they received. I look at them under my stereo microscope (Ample Scientific SM Plus Stereo Microscope). Here are mom’s fiery red colored Burmese Ruby. It was measured at 0.25 ct.

Try to adjust the illumination with top light, bottom light and both:

With the bottom illumination, the reflection was gone. The ruby displayed the beautiful deap red color.
Here is Megan’s light blue Topaz in Oval Shape. It was measured at 3.64 ct.

Overall, we are very enjoying our trip to the show. We have learns so much from the show for things like: different kinds of gems, minerals, rocks and fossils around the world, how the they are formed, how gemstones are collected, processed and presented etc. We were a little bit disappointed about the scratches on the gemstones when we look at it from the microscope but they are still very pretty to look at. We will certainly bring our microscope next time.
