Center Stone Quality Indicators
Without lab reports in the public domain, objective cut, color, and clarity grades remain unconfirmed. In celebrity contexts, buyers typically prioritize strong symmetry, excellent polish, and minimal inclusions visible to the naked eye. If comparable to high-end market standards, the center diamond would likely be D–G color and VVS–VS clarity, paired with an Excellent cut grade to maximize fire and structure.
Side Stone Execution
The tapered side setting uses accurately matched diamonds with consistent color and clarity across the arc. Micro-pavé or channel techniques are common at this quality tier to ensure a seamless, bright perimeter. The transition from center to shoulders is crafted to avoid visual breaks, supporting long-term wear and comfort.
Valuation and Industry Benchmarks
Based on retail valuation norms for exceptional 10-carat round brilliants with strong cut, color, and clarity, the center stone alone can range from $150,000 to several million depending on pedigree and customization.
