Greetings IktanStudio,
You can export or copy the style you created.
The current solution would be using the WordPress Import & Export Tool.
Please follow the steps from the following video: http://screencast.com/t/D5RXnYYRVF
** Warning : We deleted all our styles to replicate a new environment if on your part is not necessary than don’t mimic this part.
Steps:
1. Export your styles (you will export all of them)
2. Check if WordPress importer is installed (if not you can do so from here)
3. Import styles from file, assign user
4. Delete unnecessary styles

Good luck with your work,
