What It Is

GemCad.com is a software site focused on computer-aided design for faceted gemstones, built around two core tools: GemCad and GemRay. GemCad is a CAD program for faceted gemstones, designed to produce accurate faceting diagrams that users can follow when cutting on a faceting machine. GemRay uses ray tracing to render gemstone images, helping users predict how a stone will look after cutting and optimize angles for better optical performance.

Core Capabilities and Professional Focus

Based on the available content, this is not a general-purpose jewelry modeling tool, but software aimed at the highly specialized workflow of gemstone faceting. GemCad emphasizes geometrically executable designs, reducing the need for repeated angle adjustments during cutting. GemRay focuses on validating the visual result, helping users assess whether a designed stone will deliver the desired brilliance. Together, they cover the key stages of “designing the faceting diagram — verifying optical performance — actual cutting,” making the combination useful for both faceting hobbyists and professional cutters.

Pricing, Licensing, and Compatibility

The site includes a Purchase entry point, but the captured content does not provide specific pricing, trial terms, licensing model, or payment methods, so purchase cost and commercial licensing scope cannot be evaluated. The copyright notice reads: Copyright © 2012 Robert W. Strickland. All rights Reserved. In terms of compatibility, GemCad supports Windows 95 or later, while GemRay supports Windows XP or later, indicating a traditional PC/Windows-oriented environment. Compatibility with modern systems is not further explained.

Pros and Cons

The strengths are its clear positioning, strong professional depth, and the combination of faceting-diagram output with ray-traced previews, which can help users control design results before cutting. The drawbacks are the limited amount of information disclosed on the site: it does not clearly describe collaboration features, the size of any design library, export formats, update and maintenance status, or after-sales support. The interface and system requirements also feel somewhat dated. Learning resources include YouTube videos and manuals in German and Spanish, which is helpful for international users, but access to YouTube may be restricted for users in mainland China.

Who It’s For and Access from China

It is best suited to gemstone faceting enthusiasts, jewelry studios, gemstone cutters, and users who want to verify geometry and optical performance before cutting. It is less suitable for users who need cloud collaboration, general 3D jewelry modeling, or modern team-based design workflows. Access from China cannot be confirmed from the available content, and the availability of the official site is unknown. Since the learning videos rely on YouTube, there is a risk of partial access restrictions, and payment methods are not disclosed. Users in China should confirm before purchasing that the software can be downloaded, the license can be activated, and alternative learning materials are available.
