If you are searching for a single stone that ends the hunt for a museum quality center gem, this 19.17 carat oval blue tanzanite is the answer. The gem measures 18.30 by 14.93 by 9.58 mm, and its mixed brilliant cut maximizes scintillation while preserving a rich face up color. Transparent and eye clean when evaluated at eye level, this tanzanite shows vivid color intensity and an excellent polish, offering deep saturated blue with the subtle violet undertone that collectors and bespoke clients prize. Heat treated to enhance stability and color, and sourced from Tanzania, this piece from The Natural Gemstone Company carries the provenance and craftsmanship you want when commissioning an engagement ring, a statement cocktail ring, or a one of a kind pendant.
Imagine this oval tanzanite set in a classic four prong platinum mount, flanked by a halo of fine round brilliant white diamonds to lift and electrify the blue, creating an intense contrast that reads luxurious from every angle. For a warmer, more vintage presentation, surround the tanzanite with a collar of rose gold beads and offset with three tapered baguette champagne diamonds on each shoulder for subtle warmth and balance. If you prefer color harmony, consider pairing two trillion cut Ceylon sapphires or a pair of minty green emeralds as side stones, placed horizontally to accentuate the oval length and introduce a refined color story. For a dramatic pendant, bezel the tanzanite in high polish yellow gold, add a pavé diamond bail, and hang it on a substantial chain so the gem becomes a wearable focal point that catches light and attention.
At The Natural Gemstone Company we know our clients are seeking certainty, rarity, and beauty, and this tanzanite delivers on all three counts. Its substantial carat weight and eye clean clarity mean that bespoke lapidary work will reveal a showstopper that photographs and performs beautifully in person.
