AI-assisted summary
Description from the seller
White Gold Ring 18 KT with NATURAL RUBY (CORUNDUM) 9.41 CT – Diamonds 3.00 CT – Gemological Certificate
Description
I am a jewelry enthusiast and over time I have carefully chosen pieces that truly move me.
I am selling this ring with great pleasure: it is a piece with strong personality and a striking visual impact that has made me very happy. Now I want it to pass into new hands and continue to be valued and loved as it deserves.
It is an important, imposing ring that does not go unnoticed.
I am 1.85 m tall and have a large hand—and yet, even on my hand the ring still looks large and central. This is to convey how significant its presence and visual impact are.
Made in 18 KT white gold (750/1000), with an overall weight of about 11.20 grams.
Estimated period of manufacture: around the 2000s.
NATURAL RUBY – CORUNDUM
Weight: 9.41 carats
Cut: mixed oval brilliant-cut
Dimensions: approximately 14.38 x 11.88 x 5.70 mm
Color: red
Clarity: transparent
In GEM TEST Rep. 142/11 (2011) the gem is listed as: “Ruby of Burmese origin (Myanmar)”
As reported in the technical documentation, the gem has undergone an enhancement treatment consisting of superficial resurfacing with silica-rich PbO₂-containing glass, a treatment already detected in 2011 and confirmed in the most recent gemological certificate.
DIAMONDS – Total approximately 3.00 Carats
The ruby is highlighted by an impressive double halo of brilliant-cut diamonds:
25 diamonds of about 0.08 ct each (total approx. 2.00 ct)
20 diamonds of about 0.05 ct each (total approx. 1.00 ct)
Estimated quality (as per F&H 18.81 SA – Lugano technical appraisal):
Color: G/H
Clarity: VS
The diamonds are well present, luminous and very brilliant, creating a splendid crown of light around the ruby.

Estimated composition and quality of the diamonds
Ring size
Current size: 18 (Italian size).
Ring size adjustment possible before shipping through a jeweler using laser technology (about 2 working days), by sending me a message promptly after purchase. No extra cost.
Shipping
The ring will be shipped together with all original certificates
Shipping will be via DHL Express, fully trackable.
The package will be:
Insured for the full sale amount (maximum allowed by the courier)
Carefully packed and professionally protected
Sealed after in-store verification
The ring will be delivered in an elegant jewelry box (not original to the ring), as shown in the photos, in a blue-green velvet color.
For extra peace of mind, I recommend the buyer open the package at a trusted jeweler and remove the seal there.
NOTE: The ring has been photographed in different lighting conditions to best show the ruby’s features.
The stone can appear more transparent when the ring is not worn, while once worn the ruby appears slightly less transparent and the red color looks more intense.
For this reason some photos were taken with direct light and others with more natural light, to show the stone’s color in different lighting conditions.
Final Considerations
This is a ring of great character, luminous and scenographic, designed for those who love important jewelry that stands out.
I would also like to note that I own a coordinated necklace with NATURAL RUBY (CORUNDUM) of about 13 carats, likewise surrounded by a double halo of diamonds for a total of about 4 carats, with similar gemological characteristics.
The necklace has not yet been put up for sale.
I will consider listing it in upcoming auctions once this experience is concluded.
Anyone interested in completing the set may follow my future auctions.
