i'm pertty educated about elephant ivory, so what i'm telling you is factual not a guess. Until its about 30 years old it can have allsorts of problems like wood in a sence it shrinks and cracks in a dry inviroment like vegas ans swells in a humid enviroment, this is a problem with alot of ivory cues when they come to vegas they are fine for a few months and then you can rub your fingers over the inlays or twhere the shaft meets the ferrel and the elevations are different. I cant go into names but make sure who ever you buy ivory from is pre-ban ivory its seasoned enough that it wont change, I HAVE A SMALL 30 POUND TUSK WITH A HUGE CRACK ON IT 3" inches long sorry for caps. the ivory comming in now on C.I.T.E.S. permits(sport hunted elephants is too freash to be useable, I have about 450 pounds, but a good old school cue make like Ginacue or Tad knows better, I have been to Southwests shop and theit ivory is yellow on the outside when that happens its seasoned enough and white inside, if its white on the outside it wont be reliable enough for cues, so get pre ban only it costs more but it works.
