Understanding a diamond’s anatomy empowers you to look beyond the surface beauty and make a truly informed decision.
When you admire a diamond, you’re not just seeing its brilliance — you’re witnessing the harmony between nature and precision. Every facet, angle, and proportion works together to shape the way light dances across the stone.
Let’s break down the key parts of a diamond, so you can understand what each component contributes to its brilliance and beauty.
| Diamond Feature | Details |
|---|---|
| 1. Table | The flat, topmost facet that allows light to enter and exit. It's the largest facet and central to brilliance and fire. Why it Matters: A well-sized table balances sparkle and depth. Expert Tip: Ideal table = 52%–62% of diameter. |
| 2. Crown | The section between the table and girdle, shaped by multiple facets that disperse light. Why it Matters: Influences sparkle and color dispersion. Expert Tip: Ideal angle: 34–38°. |
| 3. Girdle | The thin outer edge separating crown and pavilion. Why it Matters: Structural strength and setting grip. Expert Tip: Go for “Thin” to “Slightly Thick.” |
| 4. Diameter | The width across the top of the diamond, edge to edge. Why it Matters: Affects visible size and spread. Expert Tip: Bigger diameter ≠ higher carat. |
| 5. Pavilion | The lower portion that reflects light back to the eye. Why it Matters: Controls light return. Expert Tip: Avoid shallow or overly deep cuts. |
| 6. Lower Girdle Facets | Facets beneath the girdle that direct sparkle from the pavilion. Why it Matters: Shapes fire and scintillation. Expert Tip: Ideal: 75%–80% of pavilion length. |
| 7. Culet | The point (or small facet) at the base of the pavilion. Why it Matters: A large culet may show as a visible dark spot. Expert Tip: Choose “None” or “Very Small.” |
| 8. Total Depth | Height from table to culet as a % of diameter. Why it Matters: Impacts brilliance and overall look. Expert Tip: Round ideal: 59%–62% depth. |
