Authenticated Sports Memorabilia
Curated around Houston teams and athletes.
Charity Auction Fundraising Company in Houston
Diamonds in the Rough provides authenticated sports and music memorabilia, plus the bidding tools to sell it, to charity auctions across the Greater Houston area. Your beneficiary receives guaranteed funds from the first bid, and 100 percent of everything above that goes straight to your cause. Since 2011 we have helped organizations raise more than $17 million, supporting over 600 events a year.
Memorabilia Houston Bidders Actually Want
A signed jersey only drives bidding if the room cares about the name on it. In Houston that means Texans, Astros, and Rockets memorabilia, curated around the players your guests actually follow. We build inventory around local passion rather than a generic national catalog, because that is what turns a polite bid into a bidding war. For crowds that run broader than sports, we bring framed guitars, signed vinyl, and music memorabilia as well.
How It Works, and Why There Is No Risk to Your Organization
We bring the inventory, hand-selected and fully authenticated. Your beneficiary is guaranteed proceeds starting with the very first bid, and anything the items sell for above that guarantee goes entirely to your cause. Your committee does not buy inventory, front costs, or carry unsold items.
