Description

This 18K gold three-stone diamond ring features a natural princess-cut center diamond weighing 1.08 carats, flanked by two trillion-cut side diamonds totaling approximately 0.40 carat. The center stone carries a clarity grade of SI1 and a color grade of H, set in a platinum head for added durability and bright metal contrast against the warm 18K gold band. The pairing of platinum prongs with a gold shank is a traditional approach used to maximize the stone's brilliance while keeping the overall look classic and versatile. The ring weighs 4.71 grams and displays clean, tapered lines along the shank leading into the three-stone gallery, where the princess and trillion cuts are set to complement one another in a balanced, symmetrical arrangement. This style has long been favored for engagement rings and anniversary bands for its clean geometry and the way the side stones frame the center diamond. The ring is presented ready for wear, with its diamond weights and grading details clearly documented for the buyer's reference. It is a strong choice for those seeking a substantial center diamond paired with a timeless three-stone setting in quality gold and platinum construction.
