Rubies are commonly heated to modify their color and appearance.'; with an appendix letter, stating that 'The 5.12 and 5.03 cts rubies have received the highest origin determination issued by AGL: Classic™ Burma (Myanmar). Furthermore, they possess a number of internal features that clearly indicate that these stones were unearthed from the two most important Burmese ruby sources: the historic locality of the Mogok valley (5.12 cts) and the village of Mong Hsu (5.03 cts). Individually, they each possess a richly saturated, homogeneous color that is typical of top quality gems from these famous locales. Their beautiful color is further complemented by a high clarity and a fine cut resulting in many internal color reflections and a high degree of brilliance. Traditionally rubies of this color have been described as having a "Pigeon Blood" hue...This lack of enhancement further accentuates the rarity and desirability of this pair of gemstones. With a combined weight of 10.15 carats, rubies of this size and quality are rare from any of the world's sources...Richly saturated rubies of such origin in this size and quality are rare. Finding a single gem with these attributes is already difficult. To find such a well-matched pair is that much more exclusive. They uphold and reaffirm the esteemed status of a Burmese ruby and its reputation as the premier ruby source in the world.';
