0.40 Ct. Bluish Green Sapphire from Madagascar

This exquisite transparent bluish green sapphire weighs 0.40 carat and measures 4.05 by 4.05 by 3.17 millimeters, a compact and elegant size that translates to a noticeable jewel when set in a ring or pendant. The round shape is executed with a mixed brilliant cut which combines a faceted pavilion design that maximizes return of light with a brilliant style crown that creates lively scintillation. The gem displays a light color intensity that reads as a subtle and refined bluish green under natural lighting, a hue that sits attractively between classic blue and the more contemporary green sapphires. An excellent polish enhances the gem s surface smoothness and facet crispness so that light plays across the stone with clarity and sparkle. When you consider these measured attributes together, the gem s proportions are well calibrated for both brilliance and wearability, offering an educated buyer an efficient and visually pleasing use of carat weight.

The sapphire comes to us from Madagascar, a source that has gained recognition among connoisseurs for producing a wide range of corundum colors with clean crystal structure. Madagascar sapphires form in metamorphic and alluvial deposits where aluminum oxide crystals incorporated trace amounts of iron and titanium, the elements most commonly responsible for blue and green tones in corundum. Those trace elements, in subtle amounts in this stone, yield the attractive bluish green hue that will appeal to buyers who appreciate uncommon but understated color. This sapphire has been heat treated, a standard and widely accepted enhancement in the industry that improves color and clarity by stabilizing and enhancing the natural crystal properties. Heat treatment is considered a permanent and stable treatment when properly performed, and it is routinely disclosed by reputable dealers. At The Natural Sapphire Company we are transparent about enhancements, and this gem is offered with full disclosure of its heat treatment history.

Clarity for this stone is graded as very very slightly included when evaluated at eye level, indicating that the gem appears clean to the naked eye with only minute inclusions that do not detract from the overall visual performance. For an educated buyer this is an important point, because clarity observed at eye level speaks directly to the everyday aesthetic you will see when the jewel is worn. The inclusion profile does not compromise durability, and the excellent polish means facet edges and surfaces are free of noticeable abrasions. Sapphires are corundum and rank nine on the Mohs hardness scale which makes them highly resistant to scratches and well suited for everyday jewelry. The mixed brilliant cut further disperses light across the gem so that even with a light color intensity the stone shows attractive life and movement. In practical terms this combination of clarity, cut, and hardness allows the sapphire to be set in styles meant for regular wear, including engagement rings that face daily use.

This sapphire makes a striking and thoughtful gift for someone special, offering a unique color story and enduring material quality. Bluish green is an uncommon and elegant choice that conveys individuality while remaining versatile in design settings from modern solitaires to classic halo mounted pieces. The stone s modest carat weight lends itself to pairing with accent diamonds or other colored sapphires for a personalized piece that feels more bespoke than off the shelf. Gifting a sapphire also carries symbolic meaning, as sapphires are traditionally associated with loyalty and wisdom, attributes often wished for in significant life moments. Purchasing through The Natural Sapphire Company connects you with a team experienced in sourcing and disclosing gemstone attributes, and we can advise on mounting choices that highlight the stone s color and brilliance. For care we recommend gentle cleaning with warm soapy water and a soft brush, and periodic professional checks of the setting, which will help preserve the gem s beauty for years to come. This Madagascar sapphire, with its transparent body, refined bluish green hue, excellent polish, and eye clean appearance, will become a memorable and cherished gift for an informed and discerning recipient.
