Not sure where to start?
Answer four short questions about budget, priorities, diamond type and shape. We suggest a starting specification, explain the reasoning in plain language, and point you to the guide and tool that go deeper.
What is your budget?
How this works.
A starting point, not a quote. The advisor turns four answers into a sensible first specification to shop against. It does not look up live prices or recommend a specific product.
How the carat is set. Each budget band maps to a starting lab-grown carat weight. A natural diamond costs roughly twice as much for the same specification, so the advisor sets a natural stone at about 60% of the lab-grown weight. Your priority then adjusts the grades: “biggest look” and “staying under budget” step down to H color and SI1 clarity, “best quality” holds F color and VS1 clarity at a slightly smaller size. The result is rounded to a quarter carat, never below 0.5 ct.
Where the percentages come from. The savings quoted in the reasoning use relative color and clarity premiums from a reference set of 53,940 graded natural round brilliants (the ggplot2 diamonds dataset). Only the relative differences between grades are used. The absolute prices in that set are historical and never shown.
