This elegant platinum engagement ring features a 0.50 carat oval cut center diamond surrounded by a halo of round brilliant diamonds, totaling 1.13 carats. The diamonds are graded VS2 clarity, meaning very slightly included with inclusions visible only under 10x magnification, and I color, which falls in the near colorless range of the GIA color scale.
The ring is crafted from platinum, a naturally white precious metal known for its exceptional durability and hypoallergenic properties. Platinum is approximately 90-95% pure in jewelry applications and is significantly denser and stronger than gold. The metal's durability ensures that when scratched, platinum is merely displaced rather than lost, providing superior protection for the diamond setting throughout daily wear.
The halo design creates an eye-catching appearance that makes the center stone appear larger while maximizing brilliance. All diamonds are natural and untreated, examined and graded based on 10x magnification following GIA standards. Platinum's naturally white color requires no rhodium plating and will not tarnish over time, developing instead a distinguished patina finish with age. The ring is sized 7 and can be resized within one size.
