Tourmaline comes in every shade of green from yellows that just a touch of green to blues the hate to show their green wash. This oval is a bid different green with a level of yellow that reminds me of the seaweed I use to have in my aquarium. It has good crystal and is moderately flashy, which is pretty good for a medium dark toned green. It does appreciate a good light source to show itself off the best. It weighs 2.81 carats.
