This classic platinum solitaire ring features a 1.21 carat round brilliant cut diamond set in a four- or six-prong platinum mounting. The diamond carries a VS1 (Very Slightly Included) clarity grade, meaning inclusions are difficult to detect even under 10x magnification and are invisible to the naked eye. The I color grade places the diamond in the near-colorless range, delivering a bright, brilliant appearance at excellent value.
Platinum is among the most durable and prestigious precious metals used in fine jewelry, offering natural white luster that will not fade or tarnish over time. The solitaire setting keeps the focus entirely on the center stone, making it a timeless choice for engagement rings and special occasion gifts.
