Schwartz ventured out to Tucson, Arizona with Chan to find the heart-shaped gem. The Vanderpump Rules star wrote on his Instagram Story (via Bravo), "Shout out to my dear friend @kylechandesign for helping me set this awesome heart shaped Tanzanite stone. We found it in Tucson at the gem convention."

Chan was equally excited about the trip they took to find Katie the perfect ring. "Schwartz went with me to my yearly gem hunting in the desert last year," he told Page Six. "He went all out to find her the heart from the ocean."

He added, "That was the best experience ever, even for me as a jeweler. Who gets to go with one of their best friends to pick out stones? Hunting gemstones is always fun, but hunting for one that's so meaningful is next level." Schwartz put a lot of thought into the ring and Katie's reaction made it clear he made the right decision.
