A certified diamond is a diamond that has been inspected and graded on it's 4Cs by an independent laboratory. All of our diamonds above 0.30ct are certified by reputable independent certification laboratories. 

The Four Cs are Carat, Color, Clarity and Cut. Carat is the weight of the diamond, Color is the diamond's relative saturation on the Color scale, Clarity refers to impurities contained within the diamond and on it's surface and Cut refers to how well a diamond has been polished to bring out it's beauty. 4Cs are the basic factors that influence the price of a diamond. Please visit our Education section to learn more about the 4Cs. 

Hearts & Arrows is a phenomenon which refers to the appearance of Arrows in a diamond's crown (or face-up) view, and hearts in the diamond's pavilion view when viewed through a Hearts & Arrows scope. Hearts & Arrow also refers to the level of optical and physical symmetry in a diamond. This symmetry is achieved by cutting the diamond according to very strict and exacting standards as swaying from these standards will not result in a perfect Hearts & Arrows Diamond. This perfection results in a diamond that is more beautiful and sparkly. This also results in a lot of more rough diamond wasted in the polishing process and thus comes at a premium. Hearts & Arrows diamonds are cut to most Ideal proportions and are known in the industry as Super Ideal Hearts & Arrows Diamonds. Our Signature Round Premium Ideal Hearts & Arrows series diamonds are what is known as Super Ideal Hearts & Arrows. 

An Ideal cut diamond while cut to very strict standards to reflect most light, these are second to Super Ideal Hearts & Arrows, and do not have that romantic Hearts & Arrows phenomenon. They are less symmetrical optically compared to a Hearts & Arrows but will still be a great performer compared to common cut diamonds available at every other jewellery store.  

Our Premium Princess range are hand selected Princess cut diamonds to reflect most light and these are much more brilliant and sparkly compared to other Princess cut diamonds available in the market. Our signature collection Princess range is listed on our website along with reflector image known as ASET (Angular Spectrum Evaluation Tool) scope image to help you gauge the performance of our diamonds.

An ASET scope is a device used to gauge the light return of a diamond. The blue is the head obstruction (the light that is obstructed because of the viewer), the red is strong light return, green is a weaker light return, white or black is light leakage. A customer should look to get a diamond that has most amount of red, lower amounts of green and minimal amounts of white and black. 

All certified diamonds sold by Swanstar have laser inscription on their girdle and can be easily verified using a jeweller's loupe. We also encourage our customers to get all diamond products verified by an independent appraiser.
