When in search of a top-quality stone specifically the yellow sapphire, the first thing that you should consider is the color. The best form of yellow sapphire does not indicate any other colour apart from yellow but must be a natural bright yellow colour. Clearness is also a relevant issue best depicted by the fact that a quality yellow sapphire stone will bear almost no inclusions and might be difficult to distinguish from other gemstones by a naked eye. Observe that the shape, that is, the cut of the stone, should be well proportionate and perfect for maximum brightness. Also, confirm the gem’s origin and certification from an accredited gem laboratory. Certificates of authenticity affirm the genuineness of the gemstone and Nona’s value. Once you are aware of the above factors, you can easily buy a fantastic, first-rate yellow sapphire gemstone easily.
