How can I make a turtle /select/break specific blocks?

Title: How can I make a turtle /select/break specific blocks?

I was wondering if I can make a turtle better at mining by getting it to drop specific items like cobblestone and dirt, and if it is, for example, just doing a basic tunnel, and it detects a diamond on the side, it will mine that diamond then continue with the tunneling. This is no request for a big code or something, I am just wondering if there is a way to make a code kind of like this one (not one I am trying to use, just making something up to make it more understandable)

a = 1
while a ~=50 do
turtle.digForward()
turtle.forward()
a = a + 1
if turtle.detectRight() = DiamondOre, GoldOre, IronOre then
turtle.turnRight()
turtle.dig()
turtle.turnLeft()
while a ~=50 do
turtle.digForward()
turtle.forward()
a = a + 1
end

Something like that so when it is digging if there is Diamond/gold/iron ore the to right it will mine it. If this is possible please help and if it is not, it's alright I can manage without it! Thank!

Impossible (unless moded). Turtles are blind.

Well possible, but highly inefficient.

You could have the turtle turn right, compare a block in its inventory to the wall, and then decide whether or not to dig it. However that would be super slow and pointless.

It Is Possible Use This Before The Line Of Code Where He Break's The Block

	
	turtle.select(Slot) --Put In The Slot He Is Comparing To, 1-16
	turtle.compare() --Or turtle.compareDown ect.
	

turtle.compare() Is a Boolean Success Automaticly (If Block He Is Comparing To Is Correct)

Happy To Help

Bubba already said that… It will be slower than just breaking that block.
