Jewel Crime, a specialty loose-gemstone dealer based in Osaka, has launched its 109th purchase-based crowdfunding campaign on Makuake, one of Japan's leading reward-based crowdfunding platforms. The project offers rubies, sapphires, and emeralds in small portions scooped out "by the spoonful," turning the usually formal experience of admiring gems in a case into something playful and interactive.
The company specializes in "loose stones" (rough or cut gems not yet set into jewelry), a niche and little-known corner of the gem trade. By spotlighting this rare business model and pulling back the curtain on the jewelry industry, the campaign sparks curiosity among everyday consumers who rarely get a glimpse behind the scenes.
Reaching a 109th installment is itself remarkable, showing how the brand has built deep expertise in using Makuake's platform and reward design to continuously attract fans—treating crowdfunding not as a one-off fundraising event, but as an ongoing launchpad for new products.
Highlights
- 109 consecutive campaigns have turned the platform into a regular sales channel
- A niche, highly specialized business—loose gemstone dealing—is translated into approachable storytelling
- The "scoop with a spoon" concept redefines gemstones as a fun, experiential product
Why this campaign attracts support
Editorial analysis based on publicly available information. It is not a confirmed account of why backers chose to give.
The project's viability rests largely on its extraordinary track record of 109 campaigns, which suggests a loyal base of repeat supporters who return with each new release. Rather than using crowdfunding for a single promotional push, Jewel Crime has turned it into a sustained channel for product launches and early sales.
The company also leans into its rare specialization as a loose-gemstone dealer, explaining an industry and profession unfamiliar to most consumers in accessible terms—turning a product pitch into an engaging story. The catchy "spoonful of gems" framing further lowers the psychological barrier to purchasing gemstones, which are often seen as expensive and inaccessible, reframing them instead as a casual, enjoyable experience. Clear messaging around direct-import pricing adds a tangible value proposition that reinforces the motivation to back the project.

A note from the editors
Reaching a 109th campaign is a strong example of using crowdfunding as a steady sales channel rather than a one-time promotional tool. The way this highly specialized product is translated into relatable language and reimagined as an experience offers valuable lessons for businesses in other industries. It's also worth watching how the brand continues to engage repeat supporters over time.
