0.45 Ct. Bluish Green Sapphire from Madagascar

This 0.45 carat round bluish green sapphire presents a refined balance of size, color, and cut, making it an excellent option for an engagement center stone. The gem measures 4.63 x 4.63 x 2.95 mm and is cut in a mixed brilliant style, which combines the scintillation of a brilliant cut with the depth and color display of step facets. The material is transparent and displays a medium intense color intensity that reads bluish green in varied lighting conditions, offering subtle shifts between soft blue and green tones as the stone moves. Clarity has been graded very slightly included, evaluated at eye level, and the inclusions are minor enough that they do not detract from overall transparency or brilliance. The gem has an excellent polish, contributing to crisp facet junctions and a lively surface appearance. The sapphire has been heat treated, a standard and stable enhancement intended to improve color and clarity, and it originates from Madagascar, a source known for producing a wide range of attractive sapphire hues.

As an engagement ring stone this sapphire performs well for those seeking a distinctive but wearable option, combining classic round shape presence with uncommon bluish green coloration. At 0.45 carat the stone offers elegant finger coverage without dominating delicate settings, and the mixed brilliant cut ensures balanced light return and lively sparkle under everyday conditions. The medium intense color intensity provides sufficient saturation to be recognizable as a colored stone, while remaining versatile against various metals and settings. Paired with a warm rose gold or yellow gold mounting the green component becomes more pronounced, and paired with white gold or platinum the bluer aspects are emphasized, allowing customization to match personal style. The very slightly included clarity grade means the stone appears clean to the unaided eye, which is an important consideration for engagement jewelry that will be viewed closely on a regular basis. The excellent polish preserves crisp reflections, and the mixed brilliant cut helps mask minor inclusions by breaking up background contrast, making this sapphire a practical and attractive choice for a ring intended for daily wear.

The Natural Sapphire Company stands behind the provenance and quality of this Madagascar origin sapphire, and we can assist in selecting a setting that maximizes both its beauty and durability. Sapphires are second only to diamonds on the Mohs hardness scale among common gem materials, offering strong resistance to scratches and abrasion when set and worn responsibly, which is an advantage for an engagement piece that will be worn daily. Heat treatment applied to this stone is a widely accepted and stable practice in the trade, and it enhances the natural color and clarity without materially affecting durability. For settings, consider secure prong configurations, bezel options for extra protection, or halo styles to increase visual weight without changing the stone. Our design team can recommend proportions, gallery depth, and bezel thickness to maintain comfort while protecting the girdle and pavilion. We also provide guidance on care, recommending routine inspection of the setting, gentle cleaning with mild soap and water, and avoidance of harsh chemicals and extreme thermal shock.
