Lumi's Take

About 70–80% of SI1 diamonds in this shape are eye-clean. Good odds, but not a guarantee. Always view the specific stone. If the inclusion is a small feather near the edge, you're fine. Central dark crystals? Pass and find another SI1 — there are plenty.

Introduction

When shopping for diamonds, clarity is a crucial factor that can significantly impact appearance and value. The term SI1 (Slightly Included 1) refers to a diamond clarity grade where inclusions are noticeable under magnification but may not always be visible to the naked eye. This guide will explore whether a SI1 princess diamond can be considered eye-clean, providing insights to help you make an informed purchase.

What Does Eye-Clean Mean?

  • Eye-clean refers to a diamond that appears free of inclusions or blemishes when viewed without magnification.
  • An eye-clean diamond enhances its appeal and value, as it looks flawless to the casual observer.
  • The perception of whether a diamond is eye-clean can depend on factors such as lighting conditions and the observer's distance from the stone.

Understanding SI1 Clarity

  • SI1 diamonds have inclusions that are noticeable under 10x magnification but may not be easily seen with the naked eye.
  • Inclusions in SI1 diamonds can vary in size, type, and location.
