This is the previous MineralBids platform. It remains online
temporarily only so customers and sellers can complete and
track transactions created before the move to the new platform.
Customers may use this site only to pay for items they
already won or purchased here and to review or track
their existing orders.
Do not place new orders, purchase Buy Now items, bid on
products, create listings, or begin new business on this
legacy site.
Sellers must ship all outstanding orders and complete
every remaining transaction as soon as possible.
This legacy site is expected to be taken offline within the
next 1–2 weeks. Customers and sellers should save or print any
order details, invoices, payment information, shipping details,
messages, or other records they may need before the site is
closed.
Sellers should certainly keep their own complete records of
all orders, customer details, payments, shipments, tracking
numbers, and completed transactions.
The new MineralBids platform is now available at
mineralbids.com. This legacy site should be
used only for completing old orders.

These geodes came from a roadcut near the village of Khadakwani in Madhya Pradesh, India around 6 years. They show interesting phases of mineral growth, in this case black chalcedony / drusy quartz lined on which calcite blades formed that later got covered with another drusy quartz layer and these rosettes of dogtooth shaped amethyst.
