Diamond Ring Dispute Between Wall Street Figures
A legal feud is brewing between two notable figures on Wall Street. Luis Trevino, a 38-year-old senior managing director at Beamonte Investments in Manhattan, is pushing for his ex-fiancée to return a substantial engagement ring—a $150,000, 6.3-carat oval diamond—through a lawsuit filed on August 21 in the Manhattan Supreme Court.
Trevino’s claim centers on the ring he gifted Laura Costanzo, who is 37 and a finance manager at Moore Capital Management. They first connected on Valentine’s Day in 2024, and by November, Trevino was already searching for the perfect ring. He proposed to Costanzo on January 11 during a holiday in Jackson Hole, Wyoming, in front of a sign reading “please marry me.” Interestingly, he even hired a professional photographer to capture the moment.
Following the joyous proposal, the couple started planning their wedding and discussed a prenuptial agreement early on. However, things took a downturn. Trevino cited “constant criticism and emotional distance” as factors in their relationship’s decline. He expressed to the Post through his spokesperson, Angélica Cabrera, that he realized it was time to move on for his own mental well-being after Costanzo vanished for a weekend without explanation.
Despite the end of their engagement on April 28, Trevino asserts he is still extending support to Costanzo and claims they are co-renting the three-bedroom apartment they once shared.
Trevino shared his frustrations about the situation, saying, “Instead of working this out amicably, I’ve been questioned about my intentions regarding starting a family.” He mentioned the demands and hostilities complicating what could have been a straightforward resolution. For now, he aims to focus on his work, including his various restaurant ventures, while expressing a desire to handle the situation with dignity.
On the other side, Costanzo’s attorney, Harriet Newman Cohen, responded to Trevino’s claims, stating that his narrative is “inaccurate” and devoid of newsworthiness. She noted that, as this is a private matter, they wouldn’t provide further comments or insights but acknowledged that settlement proposals have been made.
