This dainty but gorgeous antique sapphire diamond halo/cluster ring is a perfect everyday ring!

Circa 1900s-1920s, the ring is crafted with 18K and platinum. It features a charming antique cushion cut saturated royal blue sapphire surrounded by ten old mine cut diamonds, forming a flower motif.  

Center sapphire is approx 1.02 carat by a conservative measure (5.68mmx5.7mmx3 35mm). More importantly, the sapphire is certified by the Gemological Institute of America (GIA): Report Number 2221867985, dated April 04, 2023, stating geographic origin : Cambodia; Treatment: No indication of Heating.

The center sapphire is surrounded by 0.80 ctw charming old mine diamonds. G/H/I.  A majority of the stones are VS clarity with a couple that are lower in clarity due to minor chips and inclusions.

All the gemstones are open back and set in a platinum basket mounting, which was popular in the early 20th century. They glow with tons of rainbow color sparkles!  The ring is finished with a smooth shank (meaning it is resizable by your local jeweler).
