This is a perfect blue sapphire ring in 950 platinum and enhanced with 16 beautiful single-cut diamonds.

These gemstones are top quality natural. They are not lab-created.

The imposing sapphire is very large (10.5mm x 10.5mm) and weighs well over 6ct. This square-shaped corundum is smooth and fairly translucent. It features a beautiful greenish hue softly blending in the deep royal blue color of this magnificent gem. It is just mesmerizing.

The 16 light-catching single-cut diamonds measure approximately 1.5mm each, for a total of approximately 25cttw. They are earth mined and extremely nice (H-J and IF-VVS2). Please note that all measurements have been performed while the gems were in their respective settings to respect the integrity of the jewel.

This very elegant ring is set on a very intricate and open work gallery that projects the ring 7mm off the finger.

With its 4.2 grams of weight, it feels very nice on the finger. It would make an excellent engagement, anniversary ring, or simply a statement of good taste and luxury.

It is in very good condition with only a few surface scratches (égrisures). Any white or cloudy spots on the image is glare and/or photographic obstructions.
