I have a few anniversaries coming up this month and for quickness I made a batch of the same design up really quick and loved the way they turned out.
I used colour combo of soft sky, whisper white, pool party, emerald envy, rich razzleberry and early espresso with a wink of stella.
The background is made up from a couple of stamps from timeless texture and i cut out the tree from vertical greetings and used 3d foam to add to card. Sentiment from vertical greetings stamped in black and single gem stuck to the heart. I used wink of stella on the tree which gave it the look of the colours running.
