Platinum & 18K Yellow Gold Sapphire and Diamond Ring – 3.45ct Sapphire
Elegant, vibrant, and richly detailed, this platinum and 18K yellow gold ring showcases a stunning oval sapphire accented by a refined arrangement of diamonds. With its two-tone design and high-quality gemstones, the piece blends classic sophistication with timeless craftsmanship.
At the center is a 3.45 carat oval sapphire, measuring 9.53 × 6.81 × 6.48 mm. The sapphire has been heat treated, a traditional enhancement that brings out its vivid blue hue and clarity. It is secured in a classic four-prong platinum head, offering both strength and beautiful contrast against the gold shank.
Flanking the center stone are two oval diamonds, each approximately 6 × 4.25 mm, with a combined weight of 1 carat. Graded I–J color and VS–SI clarity, they provide soft, elegant sparkle in matching four-prong platinum settings.
Adding brilliance and refined detail, the 18K yellow gold shank is accented with 10 round brilliant-cut diamonds, totaling approximately 0.30 carat, also graded I–J color and VS–SI clarity, arranged in a delicate pavé setting.
The ring is stamped NYG PT950 750, indicating platinum and 18K gold purity and its maker’s hallmark.
