All items are fully authentic, from the metal to the gemstones, and each comes with a certificate of appraisal verifying the authenticity of the gold and diamonds or gemstones. Participate in our prestigious online auction showcasing a wide array of designer jewelry crafted from gold, diamonds, and gemstones. To register for bidding, please select the "Login / New Bidder" button located in the website menu. Follow the registration process to create a new account or log in if you already have one. Regrettably, we are unable to provide assistance with forgotten usernames or passwords. Are there any bidding fees? No, both registration and bidding are complimentary. Charges are only incurred upon winning an item, involving a temporary $1 hold on your credit card, which is promptly reversed within 24 hours for validation purposes. New items may be introduced shortly before the auction begins, thus we recommend checking regularly for updates. To ensure you secure your desired items, you may wish to consider placing a pre-bid. Our software functions similarly to a live auction, automatically placing bids on your behalf and adhering to predetermined increments when required. Finally, we kindly ask you to acquaint yourself with our terms and conditions, as all bidders are obliged to adhere to them. While most inquiries can be resolved on our website, if you have any outstanding questions, please click the "Feedback" button at the bottom of your screen, or feel free to contact us at info@michaeljohnjewelry.com.
