No reserve price - 46 pcs Diamond (Colour-treated) - 5.07 ct - Round - Fancy Blue - I1, I3 - Gem Report Antwerp (GRA)

Colored diamonds, especially those with shades of blue, are among the rarest and most fascinating gemstones, often formed when boron atoms are incorporated into the diamond’s crystal lattice. This lot includes 46 round diamonds subjected to color treatment to enhance their fancy blue hue, collectively weighing about 5.07 carats. Color treatments can involve processes such as high-temperature annealing or irradiation, which alter the stone's natural colors for aesthetic appeal. The clarity grades range from I1 to I3, indicating inclusions that are evident under magnification and sometimes visible to the naked eye, typical for diamonds in this commercial range. The diamonds come with certification from the Gem Report Antwerp (GRA), a laboratory known for gemstone grading. Such treated fancy blue diamonds offer an affordable way to enjoy the allure of colored diamonds but differ from naturally colored stones in value and origin. They are often used in fashion jewelry where vibrant color and visual impact take precedence.
