This solitaire ring from the Corona collection by Grau is crafted in 18-carat yellow gold and features a refined structure designed to showcase a natural 0.40-carat diamond as the true focal point of the piece, held by six prongs that provide stability and visual harmony, enhancing the stone’s brilliance while the warmth of yellow gold frames the composition with restraint and artisanal precision, resulting in a timeless jewel that conveys commitment, distinction and enduring elegance.
