Mapping 35,000+ Fine Jewelry Variants: How CedCommerce Migrated WJD Exclusives’ Shopify Catalog to Amazon US

About the Client

WJD Exclusives is a New York–based fine jewelry brand recognized for its real gold and diamond pieces, where product accuracy, attribute precision, and trust signals are central to how customers buy. With an established Shopify storefront housing a deep catalog of premium jewelry, the brand turned to Amazon US as a channel for broader reach and scalable marketplace growth.

Migrating to Amazon meant more than copying listings across. Fine jewelry sits in one of Amazon’s most attribute-sensitive categories, and WJD’s Shopify catalog was built on a layer of custom metafields that didn’t translate directly into Amazon’s structure. Bringing the catalog onto Amazon at full scale required precision data work, careful category compliance, and a disciplined execution model.

Challenges

When WJD Exclusives partnered with CedCommerce, the challenge wasn’t catalog quantity alone — it was technical depth. A migration of this scale, in a category this sensitive, demanded accuracy as the priority and a custom approach to data mapping.

• 35,000+ variants across metal types, sizes, and stone variations required clean parent-child mapping, with no margin for variation breakage.
• The Shopify store relied on extensive custom metafields, many of which had no direct equivalent in Amazon’s attribute schema and required manual logic to translate.
• Fine jewelry is an attribute-sensitive category on Amazon — listing suppression and customer trust issues both rise sharply when classification or attributes are inaccurate.
• Scale and precision sat in direct tension: 6,745 products and 22 product types meant the upload couldn’t be rushed without sacrificing the data integrity the category demanded.
• No SEO setup, no advertising infrastructure, and no Amazon performance history — the migration alone had to be strong enough to support organic visibility from day one.

CedCommerce’s Approach & Solutions

Our strategy focused on treating the WJD Exclusives migration as a precision data project, not a bulk catalog port. By aligning metafield mapping, variant architecture, category compliance, and listing validation under one disciplined execution framework, we built an Amazon catalog that held up under the accuracy standards of the fine jewelry category.

1. Shopify Metafield Mapping Framework

Rather than relying on out-of-the-box migration tools, we analyzed the structure of WJD’s Shopify metafields and built custom mapping logic to align them with Amazon’s attribute schema. Where direct one-to-one mapping wasn’t possible, changing rules were defined to preserve product detail and attribute integrity. The result: custom data carried over without distortion, and the catalog represented on Amazon the same way it lives on the brand’s storefront.

2. Precision Variant Architecture

With 35,361 variants spanning metal types, sizes, and stone variations, variant structuring was a high-stakes layer of the project. We built clean parent-child relationships, standardized variation themes, and validated mappings to prevent the variation breakage and duplicate listings that typically affect catalogs of this size — giving shoppers a clean browsing experience and the catalog the hygiene Amazon requires.

3. Category-Specific Template System

Fine jewelry on Amazon requires attribute precision that generic templates can’t deliver. We developed 60 tailored templates aligned to the catalog’s 22 product types, each built to meet the category’s compliance requirements and minimize listing suppression risk. The template system also created a repeatable structure for future catalog additions.

4. Accuracy-First Execution Model

Given the technical complexity, we prioritized data correctness over speed. The upload ran across ~40 working days under a disciplined QA workflow, with consistency and accuracy enforced at every step. The deliberate pace ensured the catalog launched in a stable, low-error state — protecting the brand from the rework cycles that often follow rushed large-scale uploads.

5. Listing Validation & Organic Readiness

Every listing was validated and activated with category compliance, attribute accuracy, and indexable content in place. Even without an SEO or advertising layer at launch, the catalog was structured well enough to begin generating early orders post-upload, signaling clean discoverability and a strong foundation for the brand’s next phase of Amazon growth.
