This classic solitaire ring features a 1.09 carat Round Brilliant cut diamond set in a 950 platinum band. The platinum setting provides a naturally white, lustrous finish that complements the diamond's sparkle and will not fade, tarnish, or cause skin irritation over time, making it one of the most durable and prestigious choices for fine jewelry.
The diamond is graded VVS1 (Very Very Slightly Included 1), placing it near the top of the clarity scale. At this grade, inclusions are so minute they are virtually invisible even under 10x magnification, making this stone appear flawless to the naked eye. The I color grade falls within the near-colorless range on the GIA scale, offering excellent visual brightness while representing exceptional value compared to higher color grades. The I color's subtle warmth is virtually imperceptible once the diamond is set in platinum.
The Round Brilliant cut is the most popular diamond shape, engineered with 58 facets to maximize light return and produce unmatched fire and brilliance. The solitaire design keeps the focus entirely on the center stone, a timeless setting style suited for engagement rings, anniversary rings, or any meaningful occasion. This ring includes an independent laboratory grading certificate verifying the diamond's carat weight, cut, clarity, and color characteristics.
