Buy and Sell Cheap The Seven Deadly Sins: Grand Cross Top Up Others from Trusted Sellers
Diamonds are what turn a stalled Grand Cross account into a moving one — draws, stamina refills and shop purchases all draw from the same pool. GameMarket.gg lets you buy Grand Cross top-ups from verified sellers at fair, transparent rates, with Buyer Protection on every order.
Each listing states exactly what you receive, the server it applies to, and how it is delivered, so there are no surprises. Your payment is held securely until the balance lands on your account.
Top Up Options
- Diamonds — the premium currency, spent on draws, stamina refills and shop purchases.
- Hawk Pass — the subscription-style pass that delivers steady value across its duration.
Which Offers Better Value?
For regular players, the Hawk Pass is usually the stronger purchase per dollar because it pays out across the whole period rather than in one lump. Direct Diamond packs make more sense when a limited or collaboration banner is closing and you need draws immediately — in that situation speed matters more than efficiency, since a missed collab unit may never return.
Servers
Top-ups apply to Global, Asia, Japan and Korea. Always confirm the listed server before ordering, since currency delivered to the wrong region cannot be moved.
How to Compare Sellers
Rate matters, but so does delivery speed and track record. A slightly higher rate from a seller with hundreds of completed orders and fast turnaround usually beats the cheapest listing from an unproven account — especially near a banner deadline, where slow delivery costs you the draws entirely.
Why Use GameMarket.gg?
- Verified sellers with transparent ratings and full transaction history.
- Buyer Protection — payment released only after you confirm delivery.
- Clear listings with server and scope stated up front.
- Secure chat plus 24/7 support on every order.
How to Top Up
- Pick Diamonds or the Hawk Pass.
- Share the required account details and server via secure chat — never your password unless the listing requires it.
- Pay through protected checkout.
- Confirm once the balance appears on your account.
Staying Safe
Keep every message and payment inside GameMarket.gg — deals arranged on outside apps fall outside Buyer Protection. Share only the access the job actually requires, and change your password once the work is finished.
Timing Your Purchase
Topping up in the final hours of a banner leaves no margin if delivery runs slower than advertised. Order a day or two ahead of any deadline and check the seller's stated delivery window before committing rather than after. Event cycles are worth planning around too: our guide to Grand Cross event types, currencies and exchange shops shows which windows reward saved Diamonds.
What Diamonds Are Actually Spent On
New players assume Diamonds are only for draws, but established accounts spend a large share on stamina refills for Demonic Beast farming. Since upgrade materials are the real bottleneck in Grand Cross, converting Diamonds into more boss runs often produces more account power than another handful of pulls would — our guide to how to earn and spend Diamonds in Grand Cross walks through both sides of that trade-off.
Frequently Asked Questions
