Randy Houser knows the secret to a successful proposal: the ring. When the 'Boots On' singer asked singer-songwriter Jessa Lee Yantz to marry him, he did so with a beautiful handmade ring, which has since been transformed into a custom 300-diamond halo ring. How could she say no?

According to PEOPLE, after Yantz said yes in July, the country hitmaker took her ring back to the King Jeweler in Nashville, where he originally purchased it. From there, the newly-engaged couple added some personal touches to reflect the bride-to-be's unique style -- namely, a double halo containing 5.5 carats (that's more than 300 stones) set in 18-karat gold.

“Custom designing an engagement ring with Randy and Jessa was truly insightful in regards to their personal taste and creative personalities," jeweler David King of King Jewelers tells Taste of Country. "The finished product perfectly matches Jessa’s style of haute country fashion and beauty with some extra sparkle to match her smile, and perfectly reflects Randy’s passionate love for his bride-to-be.”

"The complexity of a handmade ring of this degree was a great challenge, but the creative input and passion from both Randy and Jessa helped us create something not only gorgeous and brilliant, but tasteful and timeless," King told PEOPLE.

While Houser went to great lengths (and likely the end of his wallet) to impress his fiance, he had no idea that anyone else would really care about his impending nuptials. "I had no idea anyone would care that I’m engaged. But I want to thank everyone for their outreach and support regarding the news of our engagement," Houser said after popping the question. "Jessa makes me a better person every day, and I look forward to spending the rest of my life with her."
