Create a highly realistic and detailed logo featuring a blue diamond as the central element. The diamond should have a lifelike appearance with intricate facets and reflections to capture its brilliance and clarity. Use shades of blue to highlight the depth and sparkle of the diamond, with subtle light and shadow effects to enhance its realism. The background should be plain or minimal to ensure the blue diamond stands out prominently.
