Process the peaches. Shock them in hot water then peel, pit and slice them.
Weight them so you can distribute them evenly in the jars
While that is happening, bring the jars and rings to a boil.
When they have come to a boil, take them out and then put the sliced peaches, and the cloves into the jars. Be careful, the jars will be hot. Don't throw away the water, you will be processing the jars later in it.
Put the sugar, water, stick of cinnamon, and rose water into a pot and bring it to a boil. Stir over heat until the sugar dissolves, then put a candy thermometer into the syrup and bring to a boil, without stirring.
Cook until the syrup reaches 250F/170 C. Remove the cinnamon stick. Have the vodka ready in a heatproof measuring cup with a spout.
Pour the syrup directly into the measuring cup, then pour that over the fruit until the fruit is just covered. Close the jars and put them back in the pot for processing.
If needed, add more water so the water almost covers the jars. Boil them for 20 minutes. You will know when they are ready when you have heard all the jars "pop". Remove from the heat, and let them sit in the water until they are cool enough to touch. You can store them at this point. They must be refrigerated once they are open. You may reuse the jar and ring, but not the seal.
Notes
If you can find small enough peaches, you don't even have to remove the peach skin, you can just put them in whole, studded with a clove or two.
