Antique Certified Natural unheated Blue Sapphire Diamond 18K Gold Ring
This exquisite early 20th-century ring is a remarkable example of antique elegance and natural rarity. Crafted in luxurious 18K white gold, it features a captivating unheated natural sapphire, certified by LFG. Measuring 7.4 x 6.1 x 2.8mm, the sapphire exhibits a vivid blue hue—a luminous bright blue also referenced as cornflower blue. Likely of Ceylon origin, this sapphire is completely untreated, a quality that makes it exceptionally desirable among collectors.
Surrounding the central gem is a halo of eight sparkling old mine cut diamonds, with an estimated total weight of 1.28 carats. Their chunky facets and antique charm perfectly complement the sapphire, creating a striking visual balance between bold color and historic brilliance.
Unheated sapphires of this size and quality are increasingly rare, especially when set in original antique mountings. This ring is not only a beautiful adornment but also a true treasure from nature—an heirloom-worthy piece with enduring value and timeless appeal.
A collectible gem from a bygone era—perfect for the discerning connoisseur or an outstanding & unique engagement ring.
