Description from the seller
WHITE GOLD RING 18 KT (750) WITH NATURAL BLUE 2.30 CT BLUE SAPPHIRE AND NATURAL DIAMONDS
Elegant ladies’ ring in white gold 18 kt (750), made around 2010 and featuring a refined high-jewelry workmanship.
The central stone is a splendid natural blue sapphire (natural corundum) weighing 2.30 ct, oval faceted cut, measuring 9.15 x 7.13 x 3.46 mm. As indicated in the gemological certificate, the stone is classified as natural partially heat-treated corundum.
The sapphire is enhanced by a rich halo mounting in white gold 18 kt with numerous natural brilliant-cut diamonds set around the central stone and along the ring’s shoulders, giving notable brightness and elegance to the whole.
The diamonds present in the mounting were identified by the gemological laboratory as natural brilliant-cut diamonds. Given the presence of numerous stones of small size, the certificate does not report the total carat weight overall nor the individual characteristics of the single diamonds.
Natural brilliant-cut diamonds of various sizes
• Main diamonds: about 20 stones of ~0.02-0.03 ct each (visual estimate)
• Medium diamonds: about 30 stones of ~0.01-0.015 ct each (visual estimate)
• Small pavé diamonds: about 40 stones of ~0.003-0.008 ct each (visual estimate)
• Estimated total carat weight of diamonds: about 1.00-1.20 ct overall
• The gemological certificate identifies the stones as natural brilliant-cut diamonds but does not report the individual or total carat weight of the diamonds in the mounting.
CHARACTERISTICS
• Metal: White gold 18 kt (750)
• Total weight: 8.93 g
• Ring size: 18
• Main stone: Natural blue sapphire
• Sapphire weight: 2.30 ct
• Sapphire dimensions: 9.15 x 7.13 x 3.46 mm
• Sapphire cut: Faceted oval
• Treatment: Partially heat-treated (as per certificate)
• Secondary stones: Natural brilliant-cut diamonds
• Period: around 2010
• Gemological certificate no. C226185 enclosed
CONDITIONS
Excellent condition. Rarely worn and always carefully stored. The ring is in excellent condition, with no evident flaws, and the stones are securely set in the mounting.
SHIPPING
The jewelry has recently undergone gemological verification at the Gemmological Analysis Center of Dr. Pio Visconti (Valenza).
Following the checks, the ring was sealed directly by the laboratory in a dedicated official container, guaranteeing the correspondence between the jewel and the attached gemological documentation.
The shipment will be made via DHL Express:
• Fully trackable
• Insured for the full sale amount
• Carefully packaged
The ring will be shipped with the original gemological certificate and the laboratory’s official seal.
To ensure maximum security, the package will be personally delivered to the DHL center in the Malpensa area. DHL staff will verify the contents of the package against the attached documentation before accepting the shipment.
This process provides a high level of security and traceability throughout all transport stages.
Delivery in an elegant presentation case (not original).
NOTE
The photographs were taken under different lighting conditions to represent the jewel as realistically as possible.
The 2.30 ct natural blue sapphire and the natural diamonds appear particularly luminous and bright in person. Since no professional photographic equipment or jewelry-specific lighting was used, the images may not fully convey the stones’ true brilliance and the sapphire’s color depth.
Color, reflections, brilliance, and transparency may appear slightly different depending on lighting and the device used to view.
Because the jewel is kept in the original sealed packaging of the gemological laboratory, no alterations to the size can be made before shipment without compromising the security seal.
Any size adjustment can be easily performed by any qualified jeweler after delivery. This is a normally simple procedure for this type of mounting, with a typical cost ranging from 30 to 50 euros, depending on the professional and the extent of the modification requested.
The jewel is accompanied by the original gemological certificate from the Valenza Gemmological Analysis Center and is kept in the laboratory’s official sealed packaging.
An important, highly striking piece featuring a natural 2.30 ct sapphire, enriched with natural diamonds and accompanied by professional gemological certification.
