[QUOTE="Dihusky, post: 515123, member: 10304"] How did you identify the Ruby? Ruby is one of those gems that, due to its value, always required careful testing, firstly through a 10X loop, if it's clear and without inclusions it is unlikely to be a Ruby, as a Ruby is an included gem, even the highest quality Rubies have some inclusions. Next step is an SG test, this will clarify a lot of things and bring you much closer to an identity. A quick test on a ruby is 365nm UV, they glow, Garnet doesn't and in the Orient, Garnets are often passed off as Rubies to unsuspecting buyers, the UV test is close to fool-proof. A quick picture, garnet and ruby, quickly grabbed as an example. Doesn't matter what the rough quality is, they all glow. [img]https://www.prospectingaustralia.com/forum/img/member-images/10304/1569997176_ruby-vs-garnet.jpg[/img] The clarity and light from the Ruby concerns me, it is looking more like Garnet, the others I won't guess at as the image is not good enough to even get close to a suggestion.
