A made-to-order diamond ring is worth a different amount for every combination of stone, which ordinary product variants cannot handle. This app turns your rate sheet into a guided selector on the product page. Shoppers pick origin, carat, colour, clarity and ring size, and the total updates as they choose. Only the combinations you list are shown, so nobody orders a stone you cannot supply. The full specification carries through to the cart and the order.

• Upload your stone rate sheet as a CSV, or edit individual stones by hand.
• Shoppers only ever see stone combinations you have actually priced
• Show a different ring photo for each carat weight.
• Restyle the selector to match your theme: colours, layout, pills or dropdowns.
• Every choice is saved on the order, ready for your workshop.
