1.42 Ct. Blue Sapphire from Tanzania

Long before this pear shaped blue sapphire reached the careful hands of our lapidaries, it was formed deep within the earth, in the dramatic landscapes of Tanzania, where heat, pressure, and time conspired to create one of natures most enduring treasures. Embedded in metamorphic rock and carried by ancient rivers, this crystal grew slowly, layer by layer, acquiring its intense blue color from trace elements that found their place in the corundum lattice. Small scale miners, working with knowledge passed down through generations, located the rough crystal and brought it to light, where its original character could be appreciated, long before human hands began to shape it into its final form. The story of this sapphire begins in that remote geology and in the lives of those who work the land, a quiet procession from earth to skilled craftsmanship that is part of every gemstone we present at The Natural Sapphire Company, a lineage you will carry when you choose this stone.

When the rough reached our workshop, it revealed potential that a practiced eye immediately recognized, a transparency and depth of color that would reward a thoughtful cut. Our cutters chose a mixed brilliant cut and a pear shape to honor the stone’s natural proportions and to amplify its vibrant saturation. The finished gem weighs 1.42 carats and measures 8.31 x 5.06 x 4.46 mm, dimensions chosen to balance the stone’s depth and surface area for optimal light performance. Evaluated at eye level, the clarity is described as very slightly included, a testament to the stone’s clean appearance to the unaided eye, while the polish is excellent, leaving every facet crisp and precise. Importantly, this sapphire is in its natural state with no enhancement, a fact that preserves both its value and its honest narrative from mine to market. The mixed brilliant faceting pattern brings together the fire of a brilliant cut and the classic elegance of step or facet arrangements, producing scintillation and return of light that reward movement and viewing from any angle.

As you consider how this gem will live in your collection, imagine it as the centerpiece it was born to be, a stone that commands attention while remaining supremely versatile. The elongated pear silhouette flatters the finger, making it an exceptional choice for a solitaire ring that elongates and refines the hand, or for a pendant that draws the eye toward the throat and creates an intimate focal point. Set in a delicate halo to increase presence without overpowering the core, or presented as a clean bezel for a modern, architectural expression, the sapphire’s intense color intensity and mixed brilliant cut ensure that it remains the visual anchor in any setting. In daylight the sapphire reveals cooler, velvety blue tones, while indoor lighting can summon flashes of brighter blue that dance from the pavilion to the table, a lively performance born of excellent polish and thoughtfully executed facet junctions. At 1.42 carats and with these proportions, the gem reads as substantial without feeling oversized, a rare equilibrium that makes it an ideal candidate for bespoke commissions or as a cherished heirloom piece.
