Natural yellow sapphire (corundum), 1 stone, 1.06 ct, emerald cut, transparent and unheated, IGI-certified, origin Africa.
AI-assisted summary
Description from the seller
This elegant natural yellow sapphire impresses with its clear, harmonious coloration in the greenish yellow range, shifting from delicate champagne hue to warm, golden shimmer under different lighting conditions. The classic Emerald Cut emphasizes the stone's noble appearance and creates calm, reflective light effects with stylish brilliance.
A particularly value-enhancing feature is its complete untreated state (unheated). Color and transparency are of purely natural origin and have not been optimized through heat or other processes – an important quality criterion for collectors and enthusiasts of authentic gemstones.
The transparent structure and the typical, natural inner world give the sapphire character and authenticity without compromising its aesthetic impact. Its proportions make it ideal for classic settings such as solitaire rings, pendants, or elegant unisex jewelry pieces.

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.
