14k Gold Diamond Heart Necklace 0.67tcw Yellow Gold

The 14k Gold Diamond Heart Necklace from Treasured & Co. is built around 0.67 carats of natural round-cut diamonds, set into a heart silhouette in warm 14kt yellow gold. We call this our "Earthly" piece because every stone is naturally formed — no lab-grown substitutions, no synthetics. It's a quiet, everyday-wearable tribute to the real thing.

Stone Details

The pendant carries 0.67 total carat weight of natural diamonds. Each stone is graded G/H in color — the near-colorless range that pairs beautifully with yellow gold without showing warmth — and SI1/SI2 in clarity, so inclusions stay invisible to the naked eye. The diamonds are precision-set across the heart's surface for continuous brilliance.

Setting & Metal

The heart is crafted in 14kt yellow gold (585 purity, 58.5% pure gold by weight) — the standard for fine jewelry that's worn daily. The pendant suspends from an 18-inch yellow gold chain. Yellow gold is the metal most often associated with traditional heirloom jewelry, and it ages beautifully — a 14k gold diamond heart necklace today is a piece you'll still be reaching for in twenty years.

Why Choose Natural Diamonds?

Lab-grown diamonds have a place — they're chemically identical and 30–50% cheaper. But for an heirloom piece like a heart pendant, natural diamonds carry a meaningful provenance. They formed under Earth's mantle over millions of years; that's the story you're giving someone alongside the gift. Every stone in this piece is mined-origin and individually sourced.
