Lumi's Take

Not recommended unless you're a very experienced buyer cherry-picking specific stones. Most SI2 diamonds in this shape will have visible inclusions. Your money is better spent on SI1, where you'll have a much easier time finding an eye-clean stone.

Introduction

When purchasing a diamond, clarity plays a crucial role in determining its beauty and value. The SI2 (Slightly Included 2) grade is often a point of contention among buyers. This guide will explore whether an SI2 marquise diamond can be considered eye-clean, meaning it has no visible inclusions when viewed without magnification.

Understanding SI2 Clarity

  • SI2 Clarity Grade: Represents diamonds with noticeable inclusions that are visible under 10x magnification but may be difficult to see with the naked eye.
  • Inclusions: These can range from small crystals to feathers or clouds, impacting the diamond's appearance.
  • Marquise Cut: Known for its elongated shape, it can sometimes hide inclusions better than other cuts due to its facets.

Is an SI2 Marquise Diamond Eye Clean?

  • Factors to Consider:
    • Location of Inclusions: If inclusions are located near the edges or points of the marquise, they may be less visible.
    • Lighting Conditions: Different lighting can either enhance or hide inclusions, affecting the eye-clean perception.
    • Personal Perception: Some buyers may be more sensitive to inclusions than others.
  • General Consensus: Many SI2 marquise diamonds can be eye-clean, but it varies significantly from stone to stone.

Pros and Cons of SI2 Marquise Diamonds

  • Pros:
    • More affordable than higher clarity grades, allowing for larger carat sizes within the same budget.
    • Unique shape that maximizes sparkle and visual appeal.
    • Potential for eye-clean options, especially if carefully selected.
  • Cons:
    • Inclusions may become more visible in certain lighting or angles.
    • May not hold value as well as higher clarity diamonds.

Final Advice

  • Inspection: Always inspect the diamond in person if possible, under various lighting conditions.
  • Ask for Professional Grading: A reputable jeweler can provide insights on whether a specific SI2 marquise diamond is eye-clean.
  • Consider Alternatives: If clarity is a concern, consider looking at SI1 or VS2 diamonds for a better chance of being eye-clean.
