3.59 Ct.Tw.Total Carat Weight Blue Sapphire Pair from Ceylon (Sri Lanka)

As a specialist with The Natural Sapphire Company, I present a precisely matched pair of Ceylon blue sapphires, weighing 1.80 carats and 1.79 carats respectively, cut in an emerald shape with step cut faceting that emphasizes broad, linear flash rather than scintillation. The dimensions are 8.23 x 6.22 x 3.04 mm and 8.17 x 6.03 x 3.09 mm, a close dimensional match that yields consistent table proportions and symmetry when set as earrings or in a matched pair design. The step cut profile of these sapphires produces parallel crown and pavilion facets that present even color planes, so eye clean clarity, evaluated at eye level, is particularly desirable in this shape, and these stones meet that standard. Color is medium intensity blue, balanced between saturation and tone, which allows the emerald cut planes to reveal a uniform color field under a variety of lighting conditions. Polish is excellent, resulting in crisp facet junctions and strong reflection of light across the table and step facets. Enhancement is heat treated, a stable and commonly accepted treatment for corundum, and this has been disclosed to preserve transparency and long term stability of the material. The slight differences in length and width are within accepted lapidary tolerances for a matched pair, and the near identical weight and proportional thickness ensure even mounting pressure and optical cohesion in paired settings.

Our sourcing approach for this matched pair reflects The Natural Sapphire Company commitment to responsible and transparent procurement from Sri Lanka, historically known as Ceylon. Each sapphire in this pair was traced through documented supply chain steps, from vetted local miners and cutters to our internal inspection, including independent gemological verification of origin and disclosed heat treatment. We maintain direct relationships with suppliers on the ground, conduct periodic site visits, and require adherence to local labor and environmental regulations, with an emphasis on fair compensation and community reinvestment in mining areas. Chain of custody documentation accompanies the pair, and our disclosure of origin and treatment is part of the sales package, ensuring informed decision making for buyers who value provenance. For clients seeking a technically precise, visually harmonious matched pair with documented provenance, these step cut Ceylon sapphires represent a combination of lapidary craftsmanship, consistent optical properties, and ethically minded sourcing backed by The Natural Sapphire Company.
