Classic Diamond Rings Promo Design

I need a single, eye-catching graphic that spotlights a 20% OFF message while still showcasing two shimmering diamond rings. The overall look should feel Classic rather than overly modern, and every element—from typography to layout—must whisper luxury and exclusivity.

Here’s the scene I have in mind: a smooth blue backdrop sets a calm, refined mood; the two rings sit beside the discount headline, supporting it without stealing the limelight. Think elegant serif fonts, subtle lighting, and a restrained colour palette that lets the diamonds glimmer naturally.

Deliverable: one high-resolution file suitable for both social media and in-store display (layered PSD or AI + web-ready PNG/JPEG). Please keep all text editable and include any custom fonts or stock licences you use so I can update future campaigns with ease.
