1.67 Ct. Blue Sapphire from Tanzania

If you have been searching for a sapphire that balances understated elegance with collectible rarity your search ends here. This is a transparent 1.67 carat radiant shape blue sapphire with dimensions 6.38 x 5.02 x 5.10 mm that catches the eye with a soft and luminous presence. Its radiant cut delivers crisp facet lines and lively scintillation that is especially flattering in direct light. The color intensity is described as very light which yields an icy, ethereal blue that floats over the surface rather than dominating it. Clarity is very very slightly included evaluated at eye level which means it appears clean to the eye yet retains natural character that is prized by collectors. The gem has an excellent polish and has been heat treated to enhance its tone and stability. Origin is Tanzania which gives this stone a story and provenance that discerning buyers appreciate. At The Natural Sapphire Company we value both the aesthetic and the ethical sourcing of every sapphire and this gem is a fine example of that commitment.

For an engagement ring or signature piece this sapphire responds beautifully to careful design choices. The radiant cut offers a wonderful balance between the graceful corners of a cushion and the angular brilliance of an emerald cut so it sits with authority on the finger without feeling oversized. At 1.67 carats the gem reads as substantial in most standard settings and its measurements make it a versatile candidate for classic four prong mounts, bezel settings that emphasize its icy tone, or low profile crowns that are ideal for everyday wear. The very light blue color pairs exceptionally well with both cool and warm metals. A platinum or 18 karat white gold head will amplify the stone s inherent frost like radiance while an 18 karat rose gold mounting will introduce warmth and romance that gently intensifies the blue without overpowering it. Our gemologists at The Natural Sapphire Company can provide detailed views and measurements so you can visualize how the stone will wear on your hand or in a pendant.

When creating a custom piece the right companions will elevate this sapphire into a singular heirloom. For a timeless look surround the center with a halo of fine white brilliant cut diamonds to add contrast and increase perceived size. Small melee diamonds set into a split shank will create a sparkling frame that complements the sapphire s excellent polish. For a modern three stone design pair the sapphire with tapered baguette diamonds on either side which will accentuate the radiant cut s linear facets and create elegant visual flow. If you prefer color play consider pairing this light blue sapphire with deeper blue sapphires to create an ombre effect or with blush pink sapphires for a romantic, feminine palette. For a bold and contemporary statement combine the sapphire with green tsavorites or mint tourmalines which will highlight the cool undertones and give a fresh, unexpected contrast. In pendants a simple bezel in platinum allows the stone to float against the skin while a diamond halo elevates the luminosity for evening wear. Each pairing can be tailored by our design team to balance scale, backlighting and finger proportions so the final piece reads exactly as you envision.

Your search for a uniquely beautiful sapphire that functions as both an intimate engagement gem and a collectible stone is concluded with this Tanzanian 1.67 carat radiant. It offers an elegant combination of eye clean clarity, an excellent polish, and a delicate light blue tone that makes it versatile in design and endlessly wearable.

We provide custom sketches and CAD visualizations so you can see how diamond halos, tapered side stones, colored accents, and metal finishes will interact with this sapphire s dimensions and light performance.
