You’ll be surprised to find out that your sapphire doesn’t have colour whole throughout its body. Most likely it will have color concentrated closer to the culet of the stone and/or closer to the sides of the stone.
It is very rare, specially for a blue sapphire to have colour throughout the whole body of the stone. It is the talent of the cutter to bring the best out of this incredible natural beauty. If the colour is concentrated into one corner of the rough stone, amongst other things, cutter will almost always try to put that concentrated colour patch on the culet of the stone or to the centre. If you have a few colour patches, cutter will try to cut the stone so the colour patches are positioned around the edge. This way once the sapphire is cut, you will see the whole stone as one beautiful colour.
