About the Item

This striking vintage diamond engagement ring is centered by an impressive GIA-certified round brilliant cut diamond weighing 6.78 carats. Graded J color and I1 clarity, the center diamond offers remarkable scale, bright brilliance, and a bold, unforgettable presence on the hand. Accenting the center stone are 2 tapered baguette cut diamonds weighing approximately 0.50 carat in total, graded H color and VS clarity. Their sleek step-cut facets add refined geometric contrast and beautifully frame the round brilliant cut diamond with classic elegance. Crafted in platinum and hallmarked with a purity mark, the ring has a timeless and luxurious feel. Elegant, substantial, and full of presence, it is perfect for someone who appreciates important certified diamonds, classic three-stone styling, and refined platinum craftsmanship.
