The Seven Deadly Sins: Grand Cross Diamonds, Accounts & Top-Ups
Compare reviewed Diamond top-ups and account marketplaces for Netmarble’s turn-based gacha RPG — the 2020 game, not Origin. Grand Cross and The Seven Deadly Sins: Origin are different games from the same publisher: Origin (2026) is the open-world action RPG whose currency is Star Memory, and it has its own MMODude page. Here the currency is Diamonds, nothing in the game can be traded between players, and Netmarble’s Terms (§5.5(j)) ban selling or transferring an account — so every offer below is a third-party top-up or a whole account. Read the buying guide first.

Know Before You Buy
Trading rules, season dates and the latest patch for The Seven Deadly Sins: Grand Cross, from the publisher’s own statements.
Supreme God Odin + Ragnarok Chapter 10
- The 85M Downloads Godlike Festival opened September 23, 2026: UR [Almighty] Supreme God Odin — the first hero who can counter resurrection, guaranteed at 900 mileage — Ragnarok Chapter 10, and the Demonic Beast Battle: Surtr, introducing Ancient Holy Relic crafting materials.
- Festival events run September 23 to October 28, 2026 (KST), including a 28-day check-in worth up to 200 Diamonds.
- The global Android client sits at v2.114.0 (updated October 6, 2026). This is Grand Cross — Origin patches separately, in numbered versions.
Festival URs set account prices: accounts holding Supreme God Odin and the year’s other festival units, with Diamond stockpiles intact, price highest while the festival is live; once it closes on October 28 those units become fixed-supply.

Grand Cross Diamonds — Top-Ups
1 VENDORThis is the Grand Cross section — Diamonds, not Star Memory (that is Origin, the separate 2026 game). Diamonds buy hero Draws at 3 per draw, plus Item Shop and costume stock, and Netmarble sells them only inside the app and the platform stores: there is no official web top-up for Grand Cross. The one wired top-up market is FunPay’s player-run lots (879 on our check) — grey-market listings shown for comparison, with the delivery method to be confirmed with the seller before paying.

Grand Cross Account Sellers
5 VENDORSAccounts are priced on their UR festival rosters first — limited festival units anchor value — then Diamond and Gold stockpiles, Ragnarok and Demonic Beast Battle progress, and account rank across the Global, Asia and JP regions (an account only works in its own region). The shelf is deep: Eldorado (2,301), G2G (2,951) and PlayerAuctions (840) all run real categories. Netmarble’s Terms ban account sales (§5.5(j)) and account sharing (§3.3), so listings are shown for comparison with the risk stated plainly.

Grand Cross Boosting Services
2 VENDORSPiloted services for Grand Cross run on FunPay and G2G. Netmarble’s Terms name no boosting clause — what they ban is account sharing (§3.3), which is exactly what a piloted service is, and §7.2 makes a §5.5 breach grounds for immediate termination. Listed for comparison, with that stated.

Latest The Seven Deadly Sins: Grand Cross News
All MMO news →Frequently Asked Questions
Is Grand Cross the same game as The Seven Deadly Sins: Origin?
No. Grand Cross (2020) is Netmarble’s turn-based gacha RPG; Origin (2026) is its open-world action RPG. They use different currencies — Diamonds here, Star Memory in Origin — different accounts and different marketplaces: several sellers’ “Seven Deadly Sins” pages belong to Origin, not this game. Each has its own MMODude page.
Can you buy Grand Cross Diamonds outside the app?
Officially, no: Netmarble sells Diamonds only in the in-game shop and the platform stores, and runs no web top-up for Grand Cross. The third-party Diamond lots on FunPay are player-run listings outside Netmarble’s authorized channels (§4.1 of its Terms restricts purchases to Netmarble or its authorised stores).
Is it safe to buy The Seven Deadly Sins: Grand Cross Diamonds from these sites?
This page lists 5 reviewed sellers for The Seven Deadly Sins: Grand Cross, and each one has its own MMODude review covering delivery speed, customer support, pricing and trust. The highest-rated is IGVault at 4.6/5. FunPay scores under 4.0 and carries a Caution label, so read its review before ordering. Whichever you pick, start with a small first order and pay through the seller’s own checkout.
What's the difference between currency sellers, account sellers and boosting services?
This page lists 1 — top-up, 5 account sellers and 2 boosting services. Currency sellers deliver in-game currency directly to your account. Account sellers sell established or geared The Seven Deadly Sins: Grand Cross accounts. Boosting services have a player carry you through content on your own account.
