Description
A 14K yellow gold heart-shaped locket with a polished finish, set with a single lab-created sapphire in a heart cut. The locket opens, making room for a photo or small keepsake inside, and the surface is engravable.
Lab-created sapphires are grown in controlled laboratory conditions and share the same chemical composition, hardness, and optical properties as mined sapphires. Sapphire is the traditional birthstone for September, and lab-created versions offer the same deep blue color and brilliance as mined stones at a lower cost, without the variability of natural mining supply.

What affects the price of heart gold pendants and charms?
Metal, diamond weight and size drive the price most. Carat weight, whether the diamonds are natural or lab-grown, the pendant's overall size and how much gold it uses all play a part. Slide pendants with larger total carat weights sit higher than small polished hearts. Use the Price filter on this page to set a budget.
Which heart pendant and charm styles are most popular?
Sacred Heart of Jesus medals in yellow gold lead the list. Next come a Round Heart of Mary medal, small diamond heart and infinity pendants, and lab-grown diamond heart pendants. Heart slide pendants in white, yellow and rose gold also appear often near the top.
What is a heart slide pendant and how is it worn?
A slide pendant has an opening so a chain threads through it. The heart stays centered and moves along the chain instead of hanging from a bail. On this page, slide hearts carry the most diamonds, so they suit a special occasion, though you can wear one daily if you like.
Which heart pendants are best for everyday wear?
Smaller polished hearts and medals suit daily wear best. Solid 14K gold holds up well, and plain surfaces have no stones to catch on clothing. Larger diamond slide hearts have more sparkle and are often saved for dressier moments. See our jewelry care tips for keeping gold bright.
What is the difference between lab-grown and natural diamond hearts?
Both are real diamonds with the same sparkle and hardness. The difference is origin: natural diamonds form in the earth, while lab-grown ones are created in a lab. Each product title states which one is used, so check it, and the carat weight, before choosing.
Can I find a heart pendant that opens or holds a photo?
Yes, this page includes a heart locket. The Celtic Knot Heart Locket in 14K yellow gold is a larger, reversible design. For a heart you can personalize, browse Engravable Gold Pendants & Charms as well.
