0.40 Ct. Yellowish Green Sapphire from Madagascar

This transparent 0.40 carat round shape yellowish green sapphire, presented by The Natural Sapphire Company, combines careful proportions with a refined finish, yielding a balanced and attractive gem. The stone measures 4.32 x 4.34 x 2.80 mm, and is fashioned in a mixed brilliant cut that merges pavilion facet geometry with a faceted crown to optimize light return. Clarity is graded very very slightly included, evaluated at eye level, which means the gem is essentially eye clean with only minor internal features visible under magnification. Color is described as yellowish green with a medium intense color intensity, offering a lively but controlled saturation that preserves brightness and versatility in many mounting styles. The surface shows an excellent polish, contributing to crisp facet reflections and consistent scintillation. The sapphire has been heat treated, a stable and widely accepted enhancement for improving tone and uniformity, and its documented origin is Madagascar, a source known for producing a diverse palette of natural sapphires.

When compared to more common gemstones, this yellowish green sapphire exhibits a distinctive balance of brilliance, durability, and color stability that sets it apart. Unlike quartz family gems, such as amethyst or citrine, which have lower refractive indices and therefore less internal reflection, corundum displays stronger light return and scintillation, producing a livelier face up appearance for its size. Compared with topaz and peridot, this sapphire offers superior hardness, scoring nine on the Mohs scale, which enhances long term wearability and maintains polish and facet crispness over time. Versus diamond, which has an inherently higher refractive index and dispersion that yield exceptional brilliance, this sapphire presents a different but complementary character, with dense, well defined flashes from its mixed brilliant faceting and a colored presence that diamonds do not provide. The medium intense yellowish green hue, combined with the very clean clarity and excellent polish, allows the gem to reflect light in a clear, saturated manner without appearing overly dark or washed out. In practical terms, the cut proportions and surface finish maximize light performance for its carat weight, making this sapphire a refined choice for settings that require both visual impact and everyday resilience.
