About CaratRadar
CaratRadar is built to make diamond pricing more transparent by helping shoppers compare like-for-like certified stones across the market.
Our mission
Buying a diamond should be a confident decision, not a guessing game. Our goal is to give buyers a clear market view so they can evaluate value, compare options quickly, and avoid paying more for the same quality profile.
How CaratRadar works
- We aggregate live diamond listings and normalize key grading fields.
- We match stones by certification details to support apples-to-apples comparison.
- We calculate spread and pricing context so differences are easier to understand.
- We provide filtered discovery pages for specific buyer intents and budgets.
Our product principles
- Clarity first: important pricing context should be visible and understandable.
- Consistency: equivalent filters should lead to equivalent search results.
- Practicality: pages should help users move from research to action quickly.
- Continuous improvement: we refine page quality and data coverage over time.
What CaratRadar is and is not
CaratRadar is a decision-support and comparison platform. It is not gemological certification advice, financial advice, or a replacement for professional inspection and personal preference.
