Description from the seller
Mozambique Natural Ruby – 11.33 ct – Heart Shape – Lotus Gold Certificate
Natural 11.33 carat ruby from Mozambique, cut in a heart shape, accompanied by its Lotus Gold certificate.
This stone stands out for its significant weight, expressive heart cut, and red to pink-red color. It offers a strong visual presence and could suit an original jewelry creation, especially as a pendant or as the centerpiece of a custom piece.
According to the Lotus Gold report, the stone is a natural ruby, from Mozambique, with no indication of heating or treatment. In daylight, the color is described as red, with rich saturation and a medium tone.
The ruby displays natural inclusions visible, consistent with a natural stone of this size. Its transparency is noted as semi-transparent on the Lotus certificate. These characteristics give the stone a pronounced natural appearance, while maintaining a strong decorative presence thanks to its volume, shape, and color.
Photos were taken under controlled lighting of about 5500K to render the color neutrally. Slight color variations may occur depending on the screen, ambient lighting, or actual observing 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.
