AI-assisted summary
Description from the seller
Natural ruby (corundum) of high quality, oval faceted and with excellent overall finish. The gemstone impresses with its intense red coloration as well as very good transparency and an appealing luster.
The present gemological report confirms a natural-origin ruby from Burma (Myanmar), one of the most renowned producing regions worldwide. Particularly noteworthy is that no signs of heat treatment (NTE – No Thermal Enhancement) were detected, which makes this ruby considerably rarer and especially attractive to collectors.
The stone shows small natural inclusions typical for untreated rubies and underscores its authenticity without significantly affecting brilliance.
