First create a jSON Object from your data string using jQuery.parseJSON. Then you can iterate with $.each.

Sample

success:function(data){
    // create json object from data (string)
    jsonObj = jQuery.parseJSON( data);
    console.log(data);
    var options = '';
    // iterate through json
    $.each(jsonObj , function (key,value) {
            console.log(key);
            console.log(value);
            options += '<option value="'+key+'">'+value+'</option>';
            console.log(key + " " +value)
    });
}

Taking your json:

{"4":"Bangles","2":"Rings"}

A simple each() loop like this works:

$.each(items, function(k, values) {
    console.log(k);
    console.log(values);
});

JSFiddle Demo

Simply meaning all you had to do is

var options;
$.each(items, function(k, values) {
    options += "<option value='" + k + "'>" + values + "</option>";
});
// then append options to select...

Agree with answer by dknaack. Alternatively, try setting dataType: "json" in ajax. This ensures that in successHandler, the data object is a json object.

$.ajax({
type: "get",
dataType : "json",
...
