When purchasing a Ceylon Blue Sapphire gemstone, always adhere to the 3 C’s rule of thumb. This universal rule to decide the quality of any gemstone will help you discern the perfect Vedic gemstone from the low-quality substitutes.
The 3 C’s of Quality are: Cut, Color, and Clarity
Cut:
Often misunderstood to be the shape of the gemstone, cut generally refers to the sides on the surface of the gemstone. The outer shape doesn’t matter as much as the technique of the various cuts placed on the gemstones so that it may allow the light to pass and reflect in a way that is characteristic of every cut. An emerald cut will reflect light differently than a princess cut or cushion cut.
The main aim of a cut is to enhance the brightness of a gem and make it shine to the fullest.
Color:
The Ceylon Blue Sapphire comes in various shades of Blue. It ranges from sky blue to deep royal blue along with cornflower hues, although the preferred shade is a medium vibrant canary shade or a light champagne color.
The color that is highly recommended from a Vedic astrological point of view is the deep golden yellow color without any traces of orange in it.
Clarity:
The clarity of any gemstone depends on how clearly one can see through it. Hazy gemstones indicate impurities in the stone. Although, only man-made synthetic gemstones can be flawless. Natural gemstones will always contain traces of imperfection.
Ceylon Blue Sapphire gemstones are considered a good choice as they are almost completely clear to the naked eye i.e. ‘eye-clean'. They cannot be free from inclusions and crystal or feathers are the ones typically found in natural Sri Lankan Blue Sapphires.
