There is something undeniably magnetic about a fine Burma ruby — a depth of color that seems to glow from within rather than simply reflect light. This GIA-certified cushion-cut ruby measures 6.42 x 5.89 x 4.08mm and weighs approximately 1.38 carats, offering a beautifully balanced shape with vivid crimson-red tones and exceptional brilliance. The softly rounded cushion silhouette gives the gem a romantic, old-world elegance while still feeling refined and modern in jewelry design.
Burma rubies have long been considered the benchmark for the world’s finest rubies, prized for their saturated color and unmistakable richness. This gemstone has received traditional heat treatment, a standard and widely accepted enhancement used to bring out the ruby’s natural beauty. Elegant, collectible, and endlessly wearable, this ruby would make a breathtaking centerpiece for a custom ring or future heirloom designed to be treasured for generations.

FAQ
What are treatments?
Natural gemstones are mined from the earth and come in a range of qualities. The quality of a gem is based on their color, cut, clarity and carat weight. Treatments are used to enhance earth mined gemstones to improve quality so that they can be used in jewelry.
Treatments can affect the value of a gemstone so it is important to know if your gem is treated before you buy to make sure you're getting the value you are paying for. If you're interested in learning more about treatments visit our blog here.
