AI-assisted summary
Description from the seller
Royal Antwerp Gem
Natural Fancy Sapphire 5.04 ct
Oval Cut | GRS Swiss Lab Certified | Antwerp
DESCRIPTION
An impressive natural fancy sapphire from the corundum family, displaying an attractive greenish-yellow color combination and elegant oval brilliant/step cut.
This gemstone weighs 5.04 carats and measures approximately 10.20 x 8.95 x 6.13 mm. The oval cut enhances brilliance and light reflection while maintaining balanced proportions that suit fine jewelry settings.
Fancy sapphires are highly appreciated for their diverse natural color combinations and distinctive appearance. Greenish-yellow sapphires display an interesting interplay of green and golden-yellow tones, creating a unique visual character that differs from traditional blue sapphires.
With its substantial weight exceeding 5 carats, this gemstone offers impressive dimensions and an attractive combination of colors. Its elegant oval proportions make it particularly suitable for statement rings, exclusive pendants, and custom jewelry creations.
Photographs are taken using professional macro lighting to reveal details similar to viewing through a jeweler’s loupe. Due to magnification and lighting conditions, inclusions may appear more visible in images than under normal viewing conditions.

It is your responsibility to review all of the information provided about an object, including the condition and description, before placing an order. Sellers are responsible for the information, pictures and description provided, including the quality, quantity and nature of the jewelry supplied. A small imperfection that cannot be seen in the photo but is included in the description is not a non-conformity.

A Lab Report contains only the characteristics of an article described after it has been graded, tested, examined, and analyzed using the techniques and equipment used at the time of the examination from that specific Lab. The results of any other examination performed on the article may differ depending when, how, by whom and with which grading standard the article is examined. In addition, any changes and improvements in techniques and equipment that may have occurred which may enable the examiner to detect, among other things, the use of processes for altering the characteristics of an article which use was previously undetectable, does not automatically mean the object does not conform to its description.
