Product description

One beautiful transparent 1.25 carat asscher octagon shape blue cobalt spinel from Tanzania, measuring 5.82 x 5.64 x 4.26 mm, offers an immediate sense of refinement for anyone seeking a signature gem. The asscher cut emphasizes clean step facets and a hall of mirrors effect, allowing the intense cobalt blue to play with light while maintaining a composed, elegant face up. This gem is eye clean when evaluated at eye level, and it has an excellent polish, so the surfaces return brilliant flashes without distraction. No enhancement has been applied, so what you see is the natural, untreated color and clarity from its Tanzanian origin. At 1.25 carats the stone has presence without overwhelming a setting, making it ideal for both intimate rings and more statement oriented pieces, and The Natural Gemstone Company stands behind the accurate measurements and grading that accompany this exceptional piece.

If you are searching for the ideal engagement ring center, a rare collector stone, or a versatile jewel that adapts to daily life and special occasions, this cobalt spinel answers that need with confidence. Its intense blue reads as both sophisticated and approachable, pairing equally well with casual ensembles and formal attire, and it complements metals from platinum to warm yellow gold. The asscher cut gives architectural clarity for a modern solitaire, refined elegance for a halo design, and a sculptural charm in a bezel for everyday wear. Spinel is known for durable wearability, and this transparent, eye clean example offers the beauty and resilience that many buyers require for an item intended to be worn often. Choosing this gem from The Natural Gemstone Company means selecting a piece that ends the search, combining rarity, superb polish, untreated natural color, and versatile size. For those who desire a gem that meets the standards of both collectors and those planning a once in a lifetime moment, this Tanzanian cobalt spinel is a definitive solution, ready for setting and ready to become the cherished focal point of your next fine jewelry creation.
