Appraising the value of antique rubies is done much in the same way as modern rubies. At C. Blackburn Jewelers we will analyze the quality and rarity of the gemstone’s 4 Cs: Color, Clarity, Cut, and Carat weight. In addition, we’ll assess any extra value that may be attributed to the ruby mine in which the stone was sourced (if identified in a lab report).
Here is a quick overview of a ruby’s 4 Cs:
Ruby Color: The most important factor in valuing a ruby is its color. Rubies range in color from pink to blood-red to brownish-red. The most valuable rubies are a pure, vivid red color known as “pigeon’s blood” red.
Ruby Clarity: Like all gemstones, rubies may have inclusions or imperfections that affect their clarity. In general, the fewer inclusions a ruby has, the more valuable it is.
Ruby Cut: The cut of a ruby refers to its shape and the way it has been faceted. A well-cut ruby will reflect light and enhance the stone’s color and brilliance.
Ruby Carat Weight: The size of a ruby is measured in carats, with larger rubies generally being more valuable than smaller ones.
Other factors that can affect the value of your emerald include: color saturation (windows/zoning), treatments (such as heat, flux, or glass filling), damage to stone (chips, cracks, abrasions), origin of mine (for example, Mozambique), lab report (GIA or IGI), and branding (such as a Tiffany ruby brooch).
