Hi @RySid ,
I highly recommend giving the Easify Product Options app a try. This app allows you to create custom options for your customers to select directly on the product page. Here’s a quick demonstration and suggestion on how you can set it up 
:
- Install the app and create a new option set:
- Add a Text Area option to let your customers write a note, or use a Text Box option for the text they want engraved onto the jewelry.
Text Area:
Text Box:
- For additional personalization, consider adding an option for customers to select the font for the engraved text. You can use either the Dropdown or Image Swatches option type for this purpose.
Dropdown with images:
Image Swatches:
- Add a File Upload option, allowing your customers to upload the image or file containing the design they want to engrave onto the jewelry.
- After creating your option set, make sure to assign it to the relevant jewelry products on your site:
For reference, you can check out some similar demos created by the Easify Product Options app.
The app offers an intuitive live preview, making it very user-friendly. I encourage you to experience the app yourself to see how seamlessly it works
