Miruu guides

Choose the diamond for the ring, not the report.

Start with carat, cut, color, and clarity, then bring every grade back to the ring you want made, the hand it will sit on, and the tradeoffs a buyer can actually see.

Complete guide

Use the 4Cs to choose the right diamond for the ring

The 4Cs are useful because they help you ask better questions: how much presence, how much sparkle, how white, and how clean to the eye.

Start here if carat, cut, color, and clarity still feel like separate ideas.

Diamond basics

Read by the question you are trying to answer.

Buyer questions

The first answers should be simple.

What matters most among the 4Cs?
Cut often deserves early attention because it affects sparkle and light return. After that, judge carat, color, and clarity by the ring being made.
Do I need a flawless diamond?
No for most engagement rings. If two stones both look clean to the eye, the better use of spend may be cut, carat, color, or the setting.
Is carat the same as size?
No. Carat is weight. Shape, cut proportions, setting, and finger size all affect how large a diamond appears.

Ring context

Grades get easier to judge when you can see the ring.

A diamond that looks strong in a grading report still has to work with metal color, band width, setting height, and finger coverage. Use the guides to narrow the question, then compare the stone inside the design you are actually considering.

Miruu perspective

The ring matters more than the grade alone.

A diamond is chosen inside a ring: the stone shape, metal color, setting height, side details, and the way it sits on the hand all change what the grades mean. Use the numbers and letters as a starting point, then bring the choice back to the ring you want to make.
