light reflection
There will be no light coming through the stone. Therefore a very well cut stone, will look like a lifeless white rock...JER
the light doesn't come from underneath a diamond, light enters from the top, reflects off the bottom facets twice then returns out the top. so set correct a diamond will shine great set into a cue.
i am a jeweler and wanted diamonds set into a cue hightower was building for me. i found 4,1/4 carat champagne color diamonds, a total of 1 carat and chris set them into ivory spears, the light brown color of the diamonds looked great on the very white ivory.
imo a white [ clear ] stone set into white color wood will not look very good, but set them into ebony and with the contrast in color they will look great. they can be set directly into the wood or first set in a gold bezel then set the bezel into the wood. its best if you have a diamond setting bur to cut the hole, a very small drop of sg to hold it in place while you put the finish on. once they are underneath the finish they are very secure. chuck starkey
