Design a geometric nameplate template with the Nyctanthes arbor-tristis flower as the main subject, placed in both opposite corners in a 3D style. Utilize studio lighting to create a modern, sleek look, complemented by a silver and blue color scheme. The center of the nameplate should feature ample negative space for text, surrounded by glass textures that add a contemporary and polished touch. Render the design in 8K ultra HD resolution to ensure sharp details and a professional finish. In post-production, incorporate cool color grading and sharp focus effects to amplify the modern and geometric aesthetic. The overall design should embody modernity and professionalism, making it ideal for various high-end applications.
