Description from the seller
18 KT White Gold Ring with NATURAL RUBY (CORUNDUM) 9.41 CT – Diamonds 3.00 CT – Gemological Certificate
Description
I am a jewelry enthusiast and, over time, have carefully chosen pieces that truly move me.
I am pleased to put this ring up for sale: it is a jewel with strong personality and a powerful visual impact that has made me very happy. Now I wish it to pass into new hands and continue to be valued and loved as it deserves.
It is a significant, 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 big and prominent. This is to convey how meaningful its presence and visual impact are.
Made in 18 Kt white gold (750/1000), with an overall weight of about 11.20 grams.
Approximate period of manufacture: around the 2000s.
NATURAL RUBY – CORUNDUM
Weight: 9.41 carats
Cut: mixed oval brilliant-cut
Dimensions: about 14.38 x 11.88 x 5.70 mm
Color: red
Clarity: transparent
In GEM TEST Rep. 142/11 (2011) the gem is indicated as: “Ruby of Burmese origin (Myanmar)”
As stated in the technical documentation, the gem has undergone a surface enhancement treatment involving silica-based fillers with PbO₂ (glass-filled), a treatment already noted in 2011 and confirmed in the most recent gemological certificate.
DIAMONDS – Total about 3.00 Carats
The ruby is accentuated by a substantial double halo of brilliant-cut diamonds:
25 diamonds of about 0.08 ct each (total about 2.00 ct)
20 diamonds of about 0.05 ct each (total about 1.00 ct)
Estimated quality (as per technical appraisal F&H 18.81 SA – Lugano):
Color: G/H
Clarity: VS
The diamonds are clearly present, bright and very sparkly, creating a splendid corona of light around the ruby.
Documentation Included

The F&H 18.81 SA appraisal states:
18 KT white gold
Total weight 11.20 g
Estimated composition and quality of the diamonds
Ring size
Current size: 18 (Italian size).
Ring size adjustment available before shipping through a jeweler with laser technology (about 2 business 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 (courier maximum insured)
Carefully and professionally packaged
Sealed after verification in a jeweler's shop
The ring will be delivered in an elegant jewelry case (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 jewelry store and remove the seal there.
NOTE: The ring has been photographed in different lighting conditions to best show the ruby’s characteristics.
The stone may appear more transparent when the ring is not worn, while when 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 under different lighting conditions.
Final Considerations
This is a ring with great character, luminous and dramatic, designed for those who love important jewelry that makes a statement.
I also own a coordinated necklace with NATURAL RUBY (CORUNDUM) of about 13 carats, also surrounded by a double halo of diamonds for a total of about 4 carats, with similar gemological characteristics.
The necklace is not yet for sale.
I will consider listing it in future auctions, once this experience ends.
