is a reflection a flaw?

Is the reflection from an inclusion considered a flaw?

Will it be able to be seen with the naked eye or just under mag?

will prongs block it out?

Inclusions frequently "reflect" or "mirror" within a diamond. The degree to which they reflect depends on their location within the stone both from a perspective of depth within the stone and the proximity to the perimeter of the diamond... This is because the pavilion facets of a diamond work very much like a circle of fun house mirrors. The inclusion is generally only counted as a single "flaw" to use your term, even though it appears more than once... Provided that the diamond is an accurately graded SI-1 or higher clarity, the inclusion and it's reflections should not be visible to the naked eye from a top down view, however inclusions are frequently visible from the side of a diamond even in the higher clarity ranges because diamonds are not faceted to hide inclusions from the side, just the top down... Whether the reflections can be hidden with a prong depends on their location... Here is an example of a primary inclusion that is reflecting throughout the stone, the primary inclusions (actual) are indicated with red arrows and the reflections are indicated with the light blue arrows... In this case, "part" of the actual inclusions could be hidden with a prong, but the reflection could not be... However, placing a prong over the actual inclusion might make the reflections less prominent...

Very nice image R&T

Are you using the Israeli Diascope?

As a consumer, I assign the Rank Amateur grade from all sides including the bottom. I know the GIA doesn't consider it a flaw when you see an inclusions from the pavillion side being reflected all around, but it sure is disconcerting to me. It can look like someone spit on the arrows side - yuck.

Maybe that's why I recommend VS stones!

Yes, MDX we are using the DiaScope as part of our arsenal, but we wouldn't recommend it to anybody... In fact, we're often tempted to beat it against the wall... The customer support for the company has been extremely poor from the delivery of the product right down to having to order a replacement bulb for the unit... We've made at least four written requests for a replacement bulb or warranty service over the past three months to no avail and a telephone call to the NYC office left off with they'll get back to us with a solution and that was four weeks ago... The top light in the unit turns off once it reaches a certain temperature and will not turn back on until the unit has cooled down completely which seems to take 1 - 2 hours... Considering the camera unit costs almost ten thousand dollars, you'd think the company would be a bit more responsive to the needs of thei r customers!

RA, even with VS clarity stones, inclusions are often visible from the side depending on their location within the stone... The good news is that these are often hidden by the prongs
