This remarkable antique engagement ring features an newly IGI-certified and inscribed Natural Diamond accented with blue sapphires and diamonds. The centerpiece is a gorgeous I SI1 antique cut diamond. While the IGI certificate classifies it as a circular round brilliant, its proportions and visual character most closely align with a Old European Cut. With a small table (46%), generous depth (60.1%), and a large open culet, this diamond embodies the distinctive charm that sets antique cut diamonds apart from their modern counterparts, and for us who adore them there is simply no comparison to their timeless beauty.
The beautifully designed platinum mounting remains in excellent condition. Delicate milgrain, pierced details, and fine engraving showcase expert craftsmanship, while diamond accents and custom-cut blue sapphires bring additional sparkle and a subtle pop of color.
