About Lustrumo
Lustrumo is an independent jewellery intelligence platform. We provide the data Australian consumers need to make informed purchasing decisions — diamond pricing, gold valuations, certification verification, and retailer ratings.
What We Do
The jewellery industry relies on information asymmetry. Retailers benefit when consumers can't easily compare prices, verify certifications, or understand what drives value. Lustrumo structures the variables that retailers intentionally obscure — separating centre stone, setting, and side stone costs so you can see exactly what you're paying for.
We are not a price comparison site. We are a value intelligence platform — a truth engine for jewellery purchases.
Our Principles
Data-First
Every estimate, rating, and recommendation is backed by verifiable data. We show our confidence scores and never hide uncertainty.
Independent
We do not accept payment from retailers for favourable ratings. Our revenue comes from consumer tools and future B2B intelligence products.
Transparent
We unbundle every valuation — centre stone, setting, and side stones are assessed separately. No opaque single-number estimates.
Australian-Focused
All prices in AUD including GST. All retailers are Australian-based or sell to Australian consumers. Market data reflects the local market.
