Platinum Diamond Pendant Necklaces

Explore 7879’s Platinum Diamond Pendant Necklaces—modern pendants crafted in 950 platinum and set with lab-grown diamonds for bright, everyday sparkle. The edit spans classic solitaires (pear, emerald-cut, round and heart shapes), halo silhouettes, and a pavé charm, with select styles pairing diamonds with colored gemstones for a slightly more distinctive look.

Designed for effortless wear and layering, the pendants sit on fine chains with 16–21" length options and slim chain widths (about 0.8–1.0mm). Diamond weights called out on product pages range from ~0.3ct accents to 1ct center stones, depending on style. The collection sits in an accessible-luxury bracket while emphasizing hallmarking, authenticity certification, gift-ready packaging, portfolio tracking, and the brand’s “sell back anytime” investment mindset.
