Close, Ms. Uras. Actual value: 0.0573509 (rounded up). That is the IRL cost to collect five Prismarine Crystals and four Prismarine Shards. Which would make one grass block equal to 17.43 Sea Lanterns, or roughly 4 Grass for a stack of them (rounded up). Source: Skyblock Economy Spreadsheet, second tab for common trade values. Hover your mouse over the "Why?" column for the math and reasoning. Best of luck in the future.
