1.66 ct Round Brilliant Laboratory-Grown Diamond

What reads well

• Crown 34.5° with pavilion 40.8° sits in the well-regarded pairing zone for brightness and fire.
• Table 56% and depth 61.5% are within the classic round brilliant range.
• D color is in the colorless range.
• VVS1 clarity: inclusions are not a practical visual factor.
• No fluorescence: no haze risk to weigh.

What deserves a closer look

• Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.
• Not stated on the report: cut grade, polish, symmetry. These are not assumed to be favorable, and confidence is lower.

What to check on the exact stone

• Can I see this stone in soft daylight away from store spotlights to verify its sparkle?
• Does the sparkle look bright and even all the way out to the edges?
• Can you confirm the stone's weight and measurements match the GCAL report before it is set?
