0.39 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One transparent round blue sapphire weighing 0.39 carat, offered by The Natural Sapphire Company, presents a refined combination of proportions and optical performance. The gem measures 4.59 x 4.68 x 2.42 mm and is faceted in a mixed brilliant cut, yielding an average depth of approximately 52 percent, which contributes to balanced light return and lively scintillation. Clarity is described as very slightly included when evaluated at eye level, providing a clean appearance to the naked eye while retaining natural character under magnification. Color is intense and evenly distributed, with an excellent polish that enhances the stone surface and facet definition. The sapphire is heat treated, a stable and widely accepted enhancement for improving color, and its documented origin is Ceylon, Sri Lanka, known for producing vivid blue material with lively tone and saturation. The combination of size, cut, and finish makes this gem suitable for fine jewelry where both presence and refinement are desired.

This sapphire adapts readily to a wide variety of jewelry settings and design approaches, offering flexibility for custom commissions and ready to wear creations. In solitaire and minimalist ring designs the apparent diameter complements petite to medium finger sizes, while a halo setting will magnify visual size and increase overall brilliance. Classic four or six prong settings highlight the mixed brilliant cut and permit maximum light entry, whereas a bezel setting provides a secure, low profile option for active wearers and daily use. The stone is also well suited for stud earrings, bezel or prong set pendants, three stone rings, and cluster designs where it can function as either a center or accent gem. Metal pairings such as platinum or 18 karat white gold emphasize the cool blue tone, while yellow or rose gold introduce warm contrast for a more vintage or contemporary look. For bespoke work, this sapphire accommodates pavé shoulders, milgrain details, and custom engraving on the mounting, and its durability as corundum makes it practical for frequent wear. Our team at The Natural Sapphire Company can advise on setting dimensions, prong count, and protective options to ensure optimal security and aesthetic outcome, and to integrate the stone seamlessly into the intended design.
