i've done some reading that diamonds with strong blue fluorescence is not visible in regular light. also that in direct sunlight, even those without fluorescence will look blue due to the sky reflecting off of it. i was just wondering if others can give me some opinion on the ring i have purchased for my future fiance.

Note in direct sunlight the ideal-cut round diamond is showing blue from the sky and dark because the light from the sun is only lighting up a few facets. The sun is a very small point light source. The other fancy shapes all have crushed ice effects because there are many small virtual facets and those stones are glowing with various reflected light bouncing all around in the stones.

This change proves the importance of understanding how light affects a diamond’s appearance. It All Begins with Diamond Cut. Diamond cut is often confused with shape, but they are very different.

One of the most common concerns that people express about their diamond is “my diamond goes dark in sunlight” and this is something that is going to happen regardless of diamond cut quality. The primary reason for this is a simple matter of human physiology.

Fluorescence can be good or bad: it can improve a diamond’s color or make the diamond look hazy. When diamonds have Slight or Faint Blue Fluorescence, for example, they don’t appear cloudy. In fact, the slight fluorescence can make the diamond appear more white. But when fluorescence makes the diamond hazy, the stone is less transparent.
