1.50 Ct. Greenish Blue Sapphire from Madagascar

One exceptional 1.50 carat emerald cut greenish blue sapphire, transparent and unenhanced, offers a rare combination of presence and refinement that is seldom available. This gem measures 6.28 by 5.98 by 4.10 millimeters, and its elongated step cut presents broad facets that draw the eye into a deep, intense color field. Evaluated at eye level with a clarity grade of very slightly included, the stone reads as clean and luminous to the naked eye, and the inclusions that do exist are minor and character giving, rather than distracting. The polish is excellent, producing crisp facet junctions and a mirror like finish that amplifies the stone body color, while the origin from Madagascar adds provenance and a distinctive regional hue profile that collectors and connoisseurs value. At The Natural Sapphire Company we carefully select unheated sapphires like this for their natural color integrity, and this example stands out for its vivid greenish blue tone that sits between classic ocean blue and a deep teal, offering an unusual and sophisticated color identity.

Viewed and worn, this emerald cut sapphire has a composed, architectural elegance, a quiet authority that reads as deliberate rather than loud, which is exactly the kind of statement a discerning client seeks. The emerald cut clarifies the gem color, so subtle shifts from teal to ocean blue become part of the jewel narrative as the light moves. In direct daylight the blue side of the spectrum comes forward, while in warmer light the green undertones lend a sensuous warmth. At 1.50 carats and with the proportions given, the stone has enough table to display its internal color and enough depth to carry saturated hue, producing a presence on the finger that is both refined and noticeable. Set as a solitaire in a four prong light and secure mounting, the gem will read as modern and minimalist, whereas a low profile bezel will protect the pavilion and produce a streamlined wearable piece for everyday elegance. Metal choice further tunes the personality, with platinum or 18 karat white gold sharpening the blue aspect and offering a crisp contemporary backdrop, 18 karat yellow gold adding a warm, almost botanical contrast that accentuates the green notes, and 18 karat rose gold creating a softly vintage romance that complements the teal in a more intimate way.

For a custom design that elevates this rare Madagascar sapphire into a truly bespoke object d art, consider complementary stones that play with color harmony and light. A halo of fine brilliant cut diamonds will lift the perceived color and add scintillation around the broad emerald table, while tapered baguette side stones or step cut diamond shoulders will echo the emerald cut geometry and create a cohesive architectural silhouette. For collectors who desire color dialogue, small mint green tsavorites placed as accent stones will mirror the sapphire green undertones and produce a lush, jewel like palette, whereas delicate pink sapphires or padparadscha sapphires will introduce a flattering warm contrast that sets the greenish blue into sharper relief. For a modern luxe approach, flanking Paraiba tourmaline accents with their electric blue green sparkle will generate an exuberant, rare gemstone conversation, and for a vintage inspired piece, champagne or cognac diamonds as side stones will soften the composition and add warmth. In a pendant, a simple bezel with a diamond pavé bail will send flashes of light to the table and offer striking mobility, and in a cocktail ring a double halo with alternating melee sapphires and diamonds can create depth and rhythm that fully embraces the center stone.

Owning an unheated, emerald cut Madagascar sapphire of this quality is an invitation into an elite circle of collectors and clients who appreciate natural rarity and exceptional craftsmanship, and at The Natural Sapphire Company we stand behind the origin, the natural state, and the ethical sourcing of this gem. This stone is not mass produced, the combination of its weight, its natural intense color, excellent polish, and its clean eye level appearance is uncommon, and we offer bespoke design consultations to ensure that the final piece is personalized and enduring. Sapphire rates nine on the Mohs scale, which makes this gem an excellent choice for daily wear, though we recommend routine professional inspection and gentle cleaning to preserve the polish and setting security. For preservation, a soft brush with mild soapy water is effective for cleaning at home, and an annual check by a trusted jeweler will maintain prong integrity and overall finish. If you wish to explore mounting options, view CAD illustrations, or discuss pairing stones that respect both your aesthetic and lifestyle, our design specialists at The Natural Sapphire Company will guide you through a private, appointment only process that ensures your piece is as unique as the gem itself, and that you become part of a small group of owners who possess something truly exceptional.
