A beautiful piece is not always a good deal.

King of Jewelry is a single-player game about trading vintage jewelry, building a collection and solving logic puzzles. From a ring found at a flea market to a matching set in your vault, learn to buy, appraise and sell while keeping enough cash for tomorrow.

Find the piece. Make the deal.

Visit flea markets, antique fairs, private collections and more exclusive venues as your business grows. The jewelry is there to see, but its value takes judgment. Is the asking price too high? Does the material match the claim? Has a flaw been overlooked? Use your expertise to find a reason to haggle, then decide whether to buy or walk away.

Appraise before you commit

Bring your purchases back for appraisal and discover what they are worth. Inspect further or accept the current estimate. Sell to a buyer now or keep the piece for another opportunity. A poor purchase can tie up your money; a well-chosen one can keep the business moving.

Find the right customer

Customers have different tastes, and their offers may disappoint. Accept a price, negotiate again or keep a favorite in your vault. Take on collection orders, gather pieces that match the requested materials and categories, and deliver the set when it is ready.

Grow your skills. Keep the books balanced.

Choose specializations in sourcing, appraisal and sales to shape your approach. Stock on the shelf is not cash in hand: weekly fees and interest still need paying, and tomorrow brings another buying trip. Celebrate reaching one million in-game cash, then keep trading for as long as you can sustain the business.

500 jewelry puzzles, at your own pace

Enter the puzzle mode directly from the main menu. Place jewelry on a grid so that every row and column satisfies its material, gemstone or category requirement. A gold ruby ring might fit several spaces. Where should it go to leave room for everything else?

Progress from introductory 3-by-3 boards to 5-by-5 challenges with additional counting rules. There is no timer or move penalty. Swap pieces, undo moves and rearrange the board. Each first completion awards a treasure chest; claim its jewelry into your business vault to keep, appraise or sell.

A collection to revisit

Discover more than 7,400 pieces, including rings, necklaces, brooches and earrings. Browse close-up images and explore different materials, designs and craftsmanship. Pieces you have seen remain in your journal, ready to search and admire even after you sell them.
