So thoughtful, this personalized necklace from the unstoppable love™ collection honors mom or grandmother. Fashioned in sterling silver, this loving design highlights a pair of heart-shaped outlines - the smaller of the two lined with the three lab-created or genuine birthstones of your choice and diamond accents. At the center of the largest heart, the 4. 0mm birthstone representing mom or grandmother glistens in a unique setting that moves with every beat of her heart and every turn of her head. Further customize the look with the name or phrase you choose - up to eight characters in length - engraved in a fancy script font. Buffed to a brilliant luster, this 18. 0-inch box chain necklace secures with a spring-ring clasp.
