1.87 Ct. Blue Sapphire from Tanzania

This transparent 1.87 carat oval blue sapphire from Tanzania stands out immediately for its weight, a key factor that elevates both value and rarity. At 8.44 x 6.38 x 3.84 mm the stone has an ideal spread that reads larger on the finger than many stones of similar dimensions, and the mixed brilliant cut amplifies its fire and light return, creating lively scintillation across the surface. Clarity is graded very very slightly included when evaluated at eye level, which means the gem delivers exceptional transparency without significant visible interruptions to color or brilliance. With medium color intensity and an excellent polish, this sapphire balances depth of hue with brightness, a combination that often becomes more difficult to find as carat weight increases. Importantly the stone is untreated, no enhancement whatsoever, a quality that is far rarer in the market and one that materially increases desirability and resale value compared to the common heat treated alternatives.

When comparing this stone to other offerings on the market the advantages are clear, at similar price points many sapphires will be smaller, more heavily included, or have undergone enhancement to improve color, whereas this Tanzanian sapphire presents a rare package of nearly two carats, fine clarity, natural color, and superior cutting and polish. The price per carat typically climbs steeply as weight reaches and exceeds the two carat threshold, so a 1.87 carat untreated stone provides disproportionate value and investment potential, offering a buyer the look and presence of a larger gem without the premium of higher carat brackets. For customers seeking an heirloom quality center stone for an engagement ring or a single stone pendant, this gem delivers a compelling combination of visual impact and long term value. At The Natural Sapphire Company we source and present sapphires with full disclosure and verification, and this Tanzanian oval is a strong example of our commitment to quality, authenticity, and client education, offering a distinct alternative to the mass market and treated stones commonly encountered elsewhere.
