Description from the seller
This classic 18K yellow gold ring features a timeless, low-profile three-stone inspired design centered around a single vibrant blue sapphire. Sourced from fine estate collections, the natural oval-cut sapphire weighs 1.69 carats, displaying a rich, deep royal blue color that catches the light beautifully. Flanking the center sapphire are six sparkling natural diamonds totaling 0.17 carats. Each side is adorned with a central princess-cut diamond set in a diamond-shaped bezel, bordered on the top and bottom by a round brilliant-cut diamond. Delivering a bright H color and VS clarity, the accent diamonds create a gorgeous contrast against the deep blue center stone. Sized at 57 EU (18 HK) and weighing 4.80 grams, this unbranded estate ring is a sophisticated and enduring statement of luxury.

EXPERT NOTES
Based on visual evidence from the provided images, the ring showcases a beautifully balanced, classic style. The central natural sapphire is a deep, velvety blue oval cut with attractive saturation, securely held by four traditional prongs. The shoulders are decorated with a geometric arrangement of diamonds: a central princess-cut diamond set in a square frame, flanked above and below by bead-set round brilliant diamonds. This creates an elegant stepped or tapered appearance that leads into a highly polished, solid 18K yellow gold band. A clear 750 gold purity hallmark and a small plant-like maker's mark are stamped on the smooth inner shank, indicating high-quality European or estate craftsmanship. The ring's low profile and solid under-gallery ensure a comfortable fit.
