It sounds like you're describing a gold heart labret stud with a titanium 7mm bar, which is autoclavable (safe for sterilization in an autoclave).
This type of jewelry is great for piercings due to its hypoallergenic properties, especially since titanium is implant-grade and less likely to cause irritation. The gold heart adds a stylish touch while keeping it safe for long-term wear.
