Custom Photo Heart Locket Necklace Twelve Constellations Temperature Sensing Color Changing Pendant Necklace

The heart-shaped pendant measures roughly 2.5 cm wide, a standard size for Soufeel photo lockets. That makes it large enough to hold a small photo while staying light on the neck. The chain is adjustable so the pendant rests at different heights depending on your neckline. Buyers who prefer a subtle look usually wear it at the shorter setting.

The pendant is built from metal with a color-changing temperature sensing surface that shifts hue as it warms. This finish is what makes the Soufeel heart locket react when you wear it against your skin. Because the color change works through temperature, the effect appears gradually rather than instantly. The locket opens so a photo can be placed inside the heart.

Open the heart pendant, place your chosen photo inside, and close it again. Soufeel designs the locket so you supply the picture yourself, which is why it is listed as a custom photo piece. Pick an image sized to fit the interior of the heart before inserting it. The twelve constellations color changing surface stays on the outside of the pendant.

You need a photo you want to place inside the heart, since the locket is meant to hold a personal image. Soufeel leaves the picture choice entirely to the buyer, so the pendant arrives ready for you to insert it. Decide on a portrait or small square image that fits the interior space. Nothing else is required beyond the photo itself.

It suits sisters, mothers, grandmothers, daughters, wives, girlfriends, aunts, and female friends. Soufeel lists it for occasions including Mother's Day, anniversaries, weddings, birthdays, Christmas, Valentine's Day, and graduations. Because the heart holds a photo, the pendant works for anyone you want to keep close. It also works as a treat for yourself rather than a gift for someone else.

It holds 4.88 out of 5 stars from 1309 customer reviews. The pendant combines a photo compartment with a temperature sensing surface that changes color as it warms, which sets it apart from a plain photo locket. Soufeel offers it in a heart shape across twelve constellation designs. Whether it suits you depends on whether you want a photo piece that also shifts color.
