1.70 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent round blue sapphire weighs 1.70 carats, and measures 6.92 x 6.93 x 4.33 mm. The stone is cut in a mixed brilliant style, combining a faceted crown and pavilion geometry that maximizes scintillation and return of light. Clarity is described as very very slightly included when evaluated at eye level, indicating that the gem presents as eye clean with only minute internal features visible to a trained observer under magnification. Color is intensely saturated, presenting a vibrant true blue that is evenly distributed across the table and crown, and the pavilion depth contributes to a lively face up appearance. The polish is excellent, providing crisp facet junctions and a smooth surface that enhances lustre and sparkle. This sapphire has been heat treated, a standard and stable enhancement commonly accepted in the trade, and is natural in origin, sourced from Ceylon, Sri Lanka, a region renowned for producing vivid and finely colored blue sapphires. The Natural Sapphire Company presents this material as a high quality example of Ceylon blue, suitable for refined bespoke settings or classic mountings.

From a gemological and practical perspective, this sapphire offers a combination of proportions and finish that translate into impressive light performance and versatility. The mixed brilliant cut has been executed to balance face up size and depth, yielding a gem that reads slightly larger than its weight might suggest due to efficient spread. The measurements allow for comfortable integration into a solitaire engagement ring, three stone design, halo setting, or as a refined pair when matched with companion gems. As corundum, sapphire rates nine on the Mohs hardness scale, providing excellent resistance to scratching for everyday wear when properly set and cared for. Heat treatment employed in this material is intended to enhance color and clarity without altering the fundamental durability of the sapphire, and this treatment is disclosed in keeping with professional standards. The very very slightly included clarity grade underscores that the gem is visually clean at arm s length, and any internal characteristics are minor and do not detract from the gem s overall beauty or structural integrity.

Beyond its physical attributes, this Ceylon blue sapphire carries a long history of symbolic and metaphysical associations that appeal to collectors and those who value the traditional meanings of gemstones. Historically, blue sapphire has been associated with wisdom, mental clarity, and fidelity, and it is often worn as a talisman for protection and insight. Many practitioners of crystal work and metaphysical traditions regard blue sapphire as supportive of enhanced concentration, disciplined thought, and clearer communication, making it a favored choice for individuals seeking to cultivate focus and integrity in personal and professional life. On an energetic level, this sapphire is commonly linked to the throat and third eye regions in chakra based systems, and it is believed to facilitate truthful expression, intuitive perception, and calming of scattered thoughts. Users who integrate gemstones into meditation or intention practices frequently choose Ceylon blue sapphires for their reputed ability to quiet the mind while sharpening discernment. These attributes are described as traditional and experiential, rather than clinical, and should be considered personal or cultural beliefs about the stone s qualities. For those who wish to wear the gem for both aesthetic and symbolic reasons, The Natural Sapphire Company recommends secure settings that protect the girdle and pavilion, routine cleaning with warm soapy water and a soft brush, and periodic professional inspection to maintain the sapphire s brilliance and structural condition.
