Description
Beautiful natural light blue sapphire with an elegant cushion cut. The stone exhibits remarkable transparency, making its delicate hue appear especially clear and vibrant. The bright, almost icy blue coloration gives the sapphire a fresh and very charming character, ideal for collectors or as a centerpiece in jewelry.
The sapphire exhibits natural inclusions typical of genuine, untreated sapphires. These give the stone an authentic, organic look and confirm its natural origin – not a synthetic stone.

Highlights
Natural sapphire, not synthetic.
Transparent, with an attractive light blue color play.
Elegant cushion cut with good light reflection.
Fully documented with ALGT certificate.
Perfectly suited for framing or collection.
Seller's Story
I have been working in the gold purchasing and jewelry trading industry for several years – with a clear focus on estates and inheritances.
My particular interest is genuine retro and vintage jewelry from the 1940s to the 1980s: rings, brooches, pendants, and cuffs with history, quality, and character.
All offered jewelry pieces come from genuine estates—carefully inspected, professionally appraised, and, when possible, with information about their origin. Many pieces are unique and non-reproducible, often featuring hallmarks, gemstone settings, or original mounts.
I only sell genuine jewelry (mostly 333, 585, or 750 gold) – no imitations, no duplicates.
Upon request, I can provide certificates, expert opinions (e.g., from ValueMyStuff), or weight information. Transparency and fairness are important to me.
Secure packaging, fast shipping (including international), and professional customer service are standard for me.
