Diamonds may be forever, but natural, good-quality rubies are more valuable. Gem buyers place this stone at the top rank for investment purposes because rubies are more rare and hold their value and market demand better than diamonds or other gemstones. If you're inspecting a tray of red conundrums (also known as rubies) for purchase, there are several different factors to consider.
You need to judge all of the following:
-Are the rubies real or simulated (fake)?
-If they are real, are they natural or synthetic?
-How are they color graded (i.e. hue, tone, saturation) and do they show color zoning?
-Have they received treatments?-
-What is their country of origin?
If you’re going to buy rubies, or any gemstones, you need to make sure that you get a truly independent appraisal.
That means an appraiser that YOU choose. Not one that the dealer recommends, not even one off a list of several that the dealer recommends.
If the truly independent appraisal looks good, then your bargain rubies might be a good deal.
Any reputable dealer will allow for independent appraisals.
Origin and lack of treatment should be certified.
