While these are not necessarily the maximum combinations that can be made for each individual item, these are the best combinations when looking at everything as a whole. Selling this item for 100,000+ ptas is also going to unlock the Resident Evil 4 Remake Astute Appraiser achievement.

This will bring its sell price up to 50,000 which equals 100,000 ptas with the multiplier.

The Elegant Crown needs to be inlaid with 1x Red Beryl, 1x Emerald, 1x Alexandrite, 1x Yellow Diamond, and 1x Sapphire. Due to the five gem slots, this piece is the only one that can achieve the highest multiplier, Five Colors, which doubles its value. The Elegant Crown is the most valuable piece of treasure on its own with a selling price of 19,000 ptas and five available gem slots, meaning it has the highest possible reward.
