The longer ratio in this emerald cut reduces the visual impact of the darker ends that are cut with standard angles. It is a bit included toward the keel, but the gemstones richer tones obscure them. Its color floats between a blue in natural light to a blue green in my yellowish light. This change is stronger than most blue tourmaline in the collection. This stone is a classic tourmaline combination that weighs 2.85 carats.
