Description from the seller
[Premium] Collectors 14k Gold & White Gold Ring (4.45g) with 1.28 ct Princess-cut Diamonds (Top D-F Color / Center Stone VVS) – Fully Bezel Set – Galerie Best in Stones (José Hennekam, 2003) – ALGT Certified
Auction Description:
An extremely rare, high-end design jewelry piece of museum quality with an exceptional provenance. This solid 14-karat yellow gold statement ring (4.45 grams) was custom-made, delivered, and set in 2003 by the renowned Dutch designer, master gemologist, and artist José Hennekam for his prestigious Galerie Best in Stones. The ring is adorned with a sleek, architectural row of 7 natural princess-cut diamonds with a substantial total weight of no less than 1.28 carats.
Exclusive Design & Bezel Settings:
The ring stands out for its exceptionally refined, modern, and secure finish. All 7 diamonds are fully prongless-set in a smooth, handmade bezel setting. The absolute centerpiece of the ring is formed by the impressive, large central diamond placed in a unique white gold oval bezel setting. This white gold accentuation reflects light optimally, making the diamond appear visually larger and more radiant. The remaining 6 princess diamonds sit perfectly in tight yellow gold bezels.
Important Quality Note for Bidders:
The official ALGT certificate states a purity range of VVS to I1. This is a highly favorable distribution: the prominent, large central diamond in the white gold bezel and five of the side stones are of exceptionally high and loupe-clean VVS quality. The lower purity grade (I1) on the certificate is caused solely by a single, small peripheral stone that contains a natural inclusion. The main focus of the ring — the prominent center stone — is therefore visually perfect and loupe-clean.
All diamonds are additionally selected in the very highest colorless rarity class: D-E-F (Top Wesselton / River – Exceptionally white).
The ring is fully certified by the renowned Antwerp Laboratory for Gemstone Testing (ALGT) under report number 94474275. The interior of the ring is also engraved/stamped with authentic inscriptions ('26-12-74; GERT 26-5-76').
