Kat 1.85


Two Tone Old European Cut Halo Engagement Ring

The Kat 1.85 ring is a vintage-inspired ring made by us right here in NYC using authentically antique diamonds. The ring centers a GIA certified 1.85-carat old European cut diamond of I color, SI2 clarity. The diamond is set in a 4-prong platinum-topped 18kt yellow gold setting. Surrounding the center stone are 14 bead-set old European cut diamonds that all combine for approximately 0.40 carats. Millegrain details highlight the setting. The ring is currently size 6 and can be resized!

Why We Love It

We love this silhouette of ring that we call "cigar band-shaped" for its unique outline and finger coverage. Bright and vibrant OECs light up across the finger in this beautifully-detailed, low-profile dream.

The dimensions of the face of the ring are 12.9 x 14.7mm.
