Hello Derek, I’m very glad that you chose Mearto for your online appraisal, Considering the photographs, overall pattern, stone quality and the metal used, I concluded that this is a Angara Engagement Ring with a 1 Carat Heated Ruby as a Center Stone and two Pieces of H Colour, SI2 clarity garade diamonds of a total of 0.32 Carats. The center stone was a AAA quality natural Ruby put in a Prong setting. The center stone was heated, heating is a process to enhace the stone's clarity. As for the diamonds, H color diamonds appear primarily colorless to the naked eye but have a faint yellow hue that’s often visible under magnification in bright lighting, especially when they’re compared to diamonds of a higher color grade. SI2 clarity grade means your diamonds have noticeable inclusions that are very easy for a diamond grader to see using 10x magnification but mostly not visible to human eye. The Metal Ring was made of 14K White Gold. The piece was worn once and in good condition without any visible faults. Made of Natural Ruby and Diamonds. Dimensions: 6 Milimeters for the Ruby. Condition: The piece was worn once and in good condition without any visible faults. Provenance: Purchased from Angara Website in September 2021. 4500-5500$.
