Frequently asked
Common questions
How do I verify a seller?
Every seller hub on Diamicore is reviewed by our team before listing. Capability, certifications and references are checked during onboarding, and the hub shows the seller’s country and product count.
How does the Leads Marketplace work?
Leads are real sourcing requests from engineers and procurement teams. Each lead has a one-time price, with no subscription. Premier Sellers receive every lead at no additional cost.
Can I message a seller privately?
Yes. Each product and seller hub has a message channel. Messages are private and only visible to the seller.
Still need a hand?
Email hello@diamicore.com or send us a message and we will route it to the right team.
