This classic platinum solitaire ring features a 1.45 carat round brilliant cut diamond set in a timeless six-prong basket setting. The round brilliant cut is the most popular and optically optimized diamond shape, engineered with 57 to 58 facets to maximize light return, brilliance, and fire.
The center diamond carries a VVS1 clarity grade, meaning inclusions are extremely difficult to detect even under 10x magnification โ placing it in the near-flawless tier of the GIA clarity scale. The H color grade falls in the near-colorless range, appearing white to the naked eye and offering an excellent balance of quality and value. The combination of VVS1 clarity and H color represents a high-performance diamond by any grading standard.
The band and setting are crafted in platinum, a naturally white, hypoallergenic precious metal that is denser and more durable than gold. Platinum holds prongs securely over time and will not fade or require replating, making it the preferred metal for fine solitaire settings. The ring's clean, unadorned silhouette allows the center stone to command full visual attention.
