Colour and Clarity: According to GIA and AGL reports, the rubies on necklace, earrings and ring are natural, with no indications of heating. Please refer to the reports for details. In our opinion, the rubies are probably from East Africa, NOT Burma. Rubies on necklace and earrings are of strong red colour, eye clean. Upon 10x loupe, there are some natural inclusions. A few stones may have surface fissures, not noticeable to naked eyes. Heart-shaped ruby on ring is of similar colour, slightly silky inclusions. Diamonds on necklace and earrings are about G to I colours, VS to SI clarity. Two rose-cut diamonds on ring are probably of K to L colours, SI clarity. Condition: Karat white gold mounts, all in very good condition.
