What information were you provided? You need a report from reputable lab, there is no way to determine color grade or clarity from a few photos
Regarding this stone, it does not look like my ideal red color - it looks like it has brown and orange color in addition to red. This is not investment grade. The clarity is not great either
okay so I would never buy a stone as an investment. The only investment grade stones are probably well beyond anyone’s budget on this forum, and there are some high rollers here!
Without a certificate from a reputable lab, one should assume a ruby is heavily treated and not worth a lot. Please read the sticky on buying colored stones - unfortunately, you are not asking the right questions here.
With Rubies you MUST have a reputable lab certificate.
A reputable lab certificate will indicate if the rubies is untreated or heated or heated with residues or heated with diffusion or heated with significant residues.
Colour and origin aside a 2 carat ruby might cost $50,000 as a totally untreated ruby down to $50 or less if highly treated. Highly treated rubies are still called “natural”.
When it comes to origin, a Burmese origin can add a lot to the price as will a “top red” colour ie vivid red or pigeon blood red to the price. Clarity is of lesser importance, obviously a transparent ruby is worth more than a translucent ruby.
As far as being “an investment”, no.
Certainly a large size unheated Burmese ruby that is top colour and transparent is likely to hold value / increase due to rarity and appeal to collectors with deep pockets but such a ruby will cost a small fortune right now.
