A 14K solid yellow gold large puff heart on an adjustable necklace is made from 14 karat gold, mixed with other metals for strength and durability. The solid aspect means that the necklace is composed entirely of this gold alloy. The necklace features a heart-shaped pendant with a puff design. The term puff often implies that the pendant has a three-dimensional and rounded appearance, creating a soft and voluminous look. An adjustable necklace means that the length of the necklace can be changed to suit different preferences or outfits. Adjustable from 16 to 18 inches for the perfect fit. This adjustability is usually accomplished through a mechanism that allows you to modify the length. This piece of jewelry combines the beauty of solid yellow gold with the charm of a puffed heart pendant. Heart motifs often symbolize love, affection, and emotion, making this necklace a potentially meaningful gift or personal accessory.
