Diamond Jewelry Sales Dashboard

I’m sharing a Power BI .pbix that already holds our diamond-jewelry data, but the current pages don’t give me the monthly sales story I need. What I want to see, clearly and interactively, is how revenue is trending month-over-month and which individual products—or product groups—are driving those swings.

Here’s what will make the file truly useful to me:
• Clean, well-labeled visuals that spotlight revenue trends across each calendar month.
• A breakdown of product-wise sales, ideally with the ability to drill from a broad category down to specific SKUs or collections.
• Accurate DAX measures (no hard-coding) so the numbers update automatically as fresh data flows in.
• A logical page layout: an overview at the top, then deeper product detail below or on a secondary page—whatever feels most intuitive.

I’m happy with the existing data model, so this is primarily about refining measures, adding the right visuals, and polishing the design so I can present it to management without further edits. Please deliver the updated .pbix and note any new tables, calculated columns, or slicers you add so I can maintain them later.
