You have a good opening bid, plus a shade to spare. Since partner has opened and jumped, there should be a slam. That is all you need to know. A no-trump contract suits your hand, so there is nothing further to do than to utter the words "six no trump." As a check, refer to the point count. You have 15 points. Partner has at least 19, with some sort of fit. The total of 34 is convincing enough for slam. Other calls merit little credit, and a bid of four no trump receives none at all. It need hardly be pointed out that on this sequence of bidding it is a no-trump raise, not the Blackwood convention.

Three diamonds 3 points

There is no reason for undue excitement. If partner's hand is predominantly hearts, you will have nothing to cheer about.
Take it easy with a simple rebid of one spade. It is true that such a bid is not absolutely forcing, but if your partner elects to pass you may be quite sure that you have reached the correct final contract. It should be noted that a two-no trump rebid shows 19 high-card points and is not recommended with a singleton in partner's suit.
