Does it matter if they aren't perfect shaped and are they better or worst one way or the other for example are these http://www.ebay.com/itm/1000-Carat-Lots-of-Unsearched-Natural-Citrine-Calcite-Rough-/250915808284?pt=Loose_Gemstones_1&hash=item3a6bbf641c
Any better or worst then either of these http://www.ebay.com/itm/66-25ct-100-NATURAL-UNHEATED-ORANGE-ROUGH-CITRINE-/280876261584?pt=Loose_Gemstones_1&hash=item416587a0d0 or http://www.ebay.com/itm/Glowing-33-95ct-Nice-Golden-Orange-Citrine-Pear-/221017399628?pt=Loose_Gemstones_1&hash=item3375a9e14c
Or are they all the same no matter what they look like and how they have been handled or are some better?
