The details
A 10K yellow gold heart charm set with a round, lab-created blue birthstone measuring 3.5mm, finished in a polished surface.
Lab-created gemstones are grown in controlled laboratory environments and share the same chemical composition, hardness, and optical properties as their mined counterparts. This process allows birthstone jewelry to be produced in consistent, vivid colors at a more accessible price point than natural stones of comparable clarity.
