GIA report 7536310248
1.00 ct Asscher Diamond
73/100 · Character
Distinctive trade-offs that should be viewed deliberately.
What reads well
- A 1.03:1 length-to-width ratio sits in the classic Asscher / square emerald range.
- Table 66% and depth 68.7% fall in the typical Asscher / square emerald range.
- No fluorescence: no haze risk to weigh.
- Medium to slightly thick girdle balances durability and weight retention.
What deserves a closer look
- The 1.00 ct weight does not match the measurements, which suggest about 0.78 ct. Check the report data before relying on this reading.
- SI1 in an Asscher / square emerald: the open step-cut table makes inclusions easier to see. View an image or video of this exact stone.
- Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
- Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.
- Screening only: for this Asscher / square emerald, check images or video of the exact stone for the concentric "hall of mirrors", the windmill pattern at the corners and any see-through window.
What to check on the exact stone
- Does the diamond look crisp and transparent in natural light, or is there any milky haze?
- Does the feather reach the outer edge where a setting prong could put pressure on it?
- With open step facets, is the center completely eye-clean without any visible dark marks?
- Can you show me the inscribed report number under a loupe before it is set?
