1.23 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.23 carat transparent oval blue sapphire from The Natural Sapphire Company measures 7.55 x 5.44 x 3.62 mm, and it combines classic proportions with a mixed brilliant cut to maximize sparkle and depth. The stone displays intense color intensity and an excellent polish, and it is graded as very slightly included when evaluated at eye level, which means it appears clean to the naked eye while retaining natural character under magnification. Originating from Ceylon Sri Lanka, this sapphire carries the lighter and lively Ceylon blue that collectors and designers prize, and the standard heat treatment is stable and widely accepted in the trade, improving color without compromising integrity. For durability, this sapphire has a Mohs hardness of 9, making it second only to diamond on the scale, and far harder and more scratch resistant than gemstones such as topaz and aquamarine which sit around 8, and emeralds which are around 7 to 7.5, so it is an excellent choice for daily wear in rings and other jewelry.

Compared to other market options this Ceylon sapphire offers superior balance of quality, value, and uniqueness, because it combines intense natural color, eye clean clarity, and an optimized mixed brilliant cut that enhances light return without sacrificing size appearance. Untreated stones of certain origins may command premium prices, and while those can be rarer and desirable, this heat treated Ceylon sapphire gives you the sought after cornflower to medium blue tones at a much more accessible price point, with workmanship and polish that compete with higher cost examples. In settings where durability matters, the Mohs 9 hardness means this sapphire will resist everyday wear better than most colored stones, and its very slightly included clarity offers a collector friendly look that still delivers strong value relative to flawless or near flawless specimens. If you are comparing options, consider that this sapphire from The Natural Sapphire Company delivers the visual appeal of fine Ceylon material, the practicality of exceptional hardness, and the cost effectiveness that makes it ideal for bespoke engagement rings or heirloom pieces, and our gem specialists are available to advise on settings that will showcase its color and brilliance.
