1.85 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This pear shaped blue sapphire weighs 1.85 carat, a weight that places it in a highly desirable size category for collectors and custom jewelry clients, and its measurements of 9.02 x 6.36 x 4.56 mm give it an elegant presence on the hand. The gem is cut in a mixed brilliant style, combining facets that enhance both dispersion and scintillation, and it is transparent with intense color intensity and an excellent polish. The clarity grade is very slightly included as evaluated at eye level, meaning that any inclusions are minor and do not detract from the overall visual purity when viewed without magnification. The origin is Ceylon, Sri Lanka, and the stone has undergone standard heat treatment to develop and stabilize its rich blue tone. At The Natural Sapphire Company we emphasize that the measured weight, precise dimensions, and these quality parameters together make this example a rare and appealing choice for a signature piece.

Weight is one of the most influential factors in sapphire valuation, and a 1.85 carat Ceylon sapphire commands attention because of the interplay between size and quality. Gemstones are priced on a per carat scale that increases at notable thresholds, and stones approaching the two carat point are significantly rarer in top color and clarity, so the 1.85 carat weight contributes directly to both the intrinsic and market value of this sapphire. In addition, the pear shape concentrates visual mass towards the rounded end, which can make the stone read larger than its weight alone might suggest, providing an excellent visual return on the investment. When assessing rarity, buyers should consider that larger, transparent Ceylon sapphires with intense saturation and very slight inclusions are produced in far smaller quantities than more common sizes or lower graded stones, reinforcing the collectible nature of this gem.

From a gemological perspective there are several factors that explain why this particular sapphire is valuable to an educated buyer, and how each grading element contributes to its desirability. Color is the primary value driver for blue sapphires, and the intense color intensity of this stone indicates a strong saturation with a pleasing tone that retains brightness without appearing too dark. The very slightly included clarity grade as evaluated at eye level means that under typical viewing conditions the stone appears clean, and this level of clarity allows the mixed brilliant cut to maximize light return and sparkle. The dimensions and depth, with a total depth of 4.56 mm, suggest well balanced proportions that support good optical performance, enabling the pavilion facets to reflect light back through the crown for lively brilliance. Heat treatment in sapphires from Ceylon is a widely accepted and stable enhancement method, applied to improve color and clarity while maintaining the natural origin, and we disclose this clearly to support transparent and informed purchasing decisions.

The provenance of Ceylon, Sri Lanka is an important attribute for many buyers and collectors, because this region has a long history of producing sapphires with lively and velvety blue hues that are prized in the marketplace. Ceylon sapphires often exhibit a medium to strong tone with a vivid presence, and the intense coloration of this example aligns with that classic profile while retaining a clear transparency. For practical use and jewelry design, the 1.85 carat weight and pear shape lend themselves to a range of settings from solitaire pendants to halo engagement rings, and the stone provides a balance between everyday wearability and visual impact. Corundum is a durable mineral with a Mohs hardness of nine, and combined with a protective setting that secures the pointed end of a pear shape, this sapphire is suitable for regular use with proper care. Collectors who prioritize both aesthetic quality and long term value will appreciate that this gem combines substantial carat weight with strong color and responsible disclosure of treatment and origin.

At The Natural Sapphire Company we present this 1.85 carat pear shaped Ceylon blue sapphire as a gem that meets the expectations of discerning buyers who seek both beauty and documented quality.
