Thank you for submitting your item for appraisal. The lot presented is composed by 3 loose stones. They are all in oval shape, briolette cut and they are green-blue color. Two of them weight 0.9ct and measure 7 x 4 x 2 mm approx. The other one weights about 1.2ct and measures 7.5 x 4 x 2.5 mm approx. Observing the photos they seem to be corundum in the sapphire variety. They look transparent, the color is a bit zoned between medium blue and green. The stones seem to have a good cut and polish. Since the characteristics of the 3 gems are similar, they could be set on jewelry in a single piece or for a jewelry set.
Thank you again and feel free to contact us if you have further questions.
