19.40 Ct. Aquamarine from Madagascar

There are few gemstones that carry the quiet authority of aquamarine, and this cushion shape treasure from Madagascar embodies that long living tradition, with a beauty that reads as both ancient and refreshingly modern. Collected and presented by The Natural Gemstone Company, this 19.40 carat aquamarine speaks to the sea borne myths and classical tastes that have made aquamarine a favorite among collectors and jewelers for centuries. Its pale blue tone recalls the calm of shallow tropical waters, a color that captivated sailors and poets alike in bygone eras, and that still conveys serenity and steadfastness today. As a single stone with considerable presence and refined proportions, it invites a narrative of legacy and continuity, a jewel to be handed down and to be worn on the occasions that shape a family story.

The gem itself is a transparent cushion shape with measurements of 16.50 x 15.59 x 11.42 mm, a generous size that anchors any custom creation with immediate visual impact. It is fashioned with a mixed brilliant cut that marries a faceted pavilion with a scintillating crown, producing both depth and open light return. The clarity is graded very slightly included evaluated at eye level, meaning the gem reads as clean to the eye while retaining small, character giving inclusions that testify to its natural origin. The color intensity is medium, offering a clear and pleasing blue that is neither washed nor overly saturated, enhanced by expert heat treatment that is stable and widely accepted in trade. The polish is excellent, giving the surface a refined mirror like finish that allows the stone to capture and release light in a lively manner.

For custom jewelry designers and discerning clients, this aquamarine is an ideal canvas due to its size and cushion form, a shape that blends classic proportions with a contemporary sensibility. The broad table and even pavilion depth allow a variety of settings to showcase the color and clarity, whether set as a dramatic solitaire in a ring, suspended as a single stone pendant, or embraced by a delicate halo of accent stones for enhanced brilliance. The generous 11.42 mm depth affords structural integrity, making it well suited to prong or bezel mounts that protect the girdle while allowing light to enter freely from the top and sides. Its substantial face up size ensures that the gem will read as a statement piece, while the cushion outline lends itself to softened lines and vintage inspired designs that celebrate tradition, or to bold modern settings that emphasize minimalism and grace.
