Laser Drilled Diamonds

Does anyone have any idea on how laser drilling of a diamond affects the price of a comparable undrilled stone? I know they are less expensive, but by what percentage of retail?

Dennis, could be as much as 50% . Depends on the diamond…

Thanks for the input.

A lot of factors to consider…
Number of laser drill holes, placement of drill holes.

Bottom line is that they are to enhance clarity, and that reduces the diamonds value considerably
