The short version
GemFind Stuller converts Stuller's iframe Showcase into a transactional storefront for $149/month (7-day trial). At the time of writing it holds a 1.0★ rating from its single review, which asks for installation guide videos that don't exist. GemFind RingBuilder is the company's flagship builder at $295–345/month, and its listing notes that moissanite and other gemstones are not supported.
Lustriel was built for exactly this job — a guided configurator over your own Stuller catalog — and starts at $0/month. Onboarding is a wizard, not a support ticket: connect your Stuller credentials, pick your series, and add the block to your theme with one click.

What the price difference buys you
At GemFind Stuller's $149/month, a year costs about $1,788 before you've sold a ring. Lustriel's free plan lets you put your five best-selling Stuller series live for nothing, prove that shoppers configure and buy, and only then upgrade — Pro is $79/month with a hundred series, advanced markup rules, and the AI concierge. The first fifty stores to finish onboarding get Pro for $29/month, locked for a year.
Where GemFind may still fit
Fairness matters: GemFind has operated since the 1990s and its JewelCloud network aggregates many diamond feeds (IDEX, RapNet, Polygon, Nivoda). If your primary need is multi-vendor loose-diamond aggregation rather than a Stuller-native configurator, RingBuilder's feed network is genuinely broad. If your business runs on your Stuller account, that's the job Lustriel is built for.
