This stunning 18-karat white gold diamond necklace features a total carat weight of 11.23 CTW of round brilliant-cut diamonds, carefully selected for exceptional sparkle and brilliance. The diamonds are graded VS1 to VS2 in clarity, meaning inclusions are very small and not visible to the naked eye, and H to I in color, placing them in the near-colorless range that pairs beautifully with white gold settings.
The round brilliant cut is the most popular and timeless diamond shape, maximizing light return and fire. With over eleven carats of total diamond weight, this necklace makes a bold, luxurious statement suitable for formal occasions or as a treasured gift. The 18-karat white gold setting provides a bright, durable, and hypoallergenic mounting that enhances the natural brilliance of the diamonds.
