Founder's Three Stone Oval Diamond Engagement Ring HT2689Designed by Tacori founder Haig Tacorian, the HT2689 is an 18k yellow gold three stone engagement ring built for oval diamonds between two and four carats. Two half moon diamonds sit at the shoulders, triple row pav runs the band and a hidden bloom beneath the crown adds a layer of brilliance most people won't notice until they look for it. A ring that was made with a very specific oval buyer in mind.
