The History of Hearts and Arrows Diamonds
As early as the 1980s, diamond cutters in Japan were able to polish round brilliant diamonds that displayed a kaleidoscopic pattern that could be observed through a refractometer. Their techniques were eventually passed on to other cutting factories. In the mid-1990s, Hearts and Arrows diamonds began to emerge in other continents.
Initially, people used a dispersion viewer to observe the pattern of Hearts and Arrows diamonds. The dispersion viewer, designed in the 1970s, is a tool that reflects symmetric light sources and displays the precise cutting of the Hearts and Arrows pattern. Today, Hearts and Arrows scopes, cutting scopes, and ASET scopes are used.
So, what is an Hearts and Arrows diamond?
It is a diamond that has been cut more accurately based on the round, 57-facet brilliant cut diamond. This cutting produces perfect optical symmetry, polish, and the best light performance through extremely high-quality cutting proportions. Less than 1% of diamonds in the world can achieve the light source symmetry accuracy required by the Hearts and Arrows pattern.
The "Hearts and Arrows" pattern
The "Hearts and Arrows" pattern refers to the actual heart and arrow shapes visible when a perfectly proportioned diamond is viewed through an hearts and arrows viewer. When viewed from the top (the crown), the diamond displays eight symmetrical arrow patterns, while from the bottom (the pavilion), it shows eight symmetrical heart patterns.

The outstanding features of Hearts and Arrows diamonds
The outstanding features of Hearts and Arrows diamonds include impeccable cutting precision, craftsmanship, and proportions. The perfect balance between fire and brilliance makes the diamond incredibly bright and sparkling. The diamond is valued for its exceptional brilliance.
The distinctive feature of Hearts and Arrows diamond
The distinctive feature of Hearts and Arrows diamond is its outstanding brilliance and beauty, making it perfect for celebrating life's most precious moments. Its internal pattern of hearts and arrows is often associated with the name Cupid, and this optical phenomenon is also known as the "Cupid effect."
Hearts and Arrows diamond is rare, and its unique qualities and superior quality make it highly valuable. From a basic perspective, it symbolizes the perfect and intricate pursuit of diamond cutting craftsmen towards diamond cutting, as well as their dedication to its beauty.
