Diatech Studio vs TiaraCAD

Diatech Studio is an AI workspace for jewelry teams to develop, find, price, review, and present designs in one project. Users can start with text, speech, sketches, reference photos, CAD files, Pinterest boards, or WhatsApp messages. Search includes natural-language and reverse-image options, with tags, filters, and version control for design archives. Studio can generate model or hand photos, product copy, and product videos of 5, 10, or 15 seconds with audio; images can be upscaled to 4K. Its browser-based 3D tools create models from 2D images, render and clean meshes, and export OBJ or STL files. Costing features include spreadsheet import, AI price estimates, a shared price book, and stone inventory matching. Boards, calendars, tasks, assignees, due dates, mentions, and notifications support team coordination. Each generated image uses one image allowance, and each video second uses one video-second, drawing from the same monthly allowance. Free costs nothing and includes 25 images; Basic is $99 a month, Pro is $399 a month, and Enterprise is $1,199 a month.

TiaraCAD is jewellery CAD software for designing rings, necklaces, bracelets, earrings, and custom diamond jewellery. It works as a plugin for Rhino, and Rhino 8 is required to evaluate it. The product describes its design approach as “Stone-First,” building metal around a stone and generating only the metal required by the design. Its tools include gem settings, modular design, detailing, and support for multiple open files. Users can import company gem charts, metal density charts, and setting parameters for default use. TiaraCAD can generate a bill of material report for a quotation in one click, and release notes say version 2.6.5 added JewelCAD file import. It is offered for macOS and Windows; the features page says TiaraCAD 2.0 works natively on macOS. A 15-day evaluation is available, with no free plan. Continuous internet access is not required, though license validation needs an internet connection once, or once every 14 days with Cloud Licensing. Listed one-time plans include TiaraCAD 2 for Rhino 8 users at $995, paid once, and TiaraCAD 2 with Rhino 8 Commercial at $1,990, paid once.
