1.89 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This one point eight nine carat round blue sapphire is a classic and versatile choice for an engagement ring, grounded in measurable qualities that an educated buyer will appreciate. The gem measures 7.37 x 7.40 x 4.11 mm, providing a substantial face up presence without overwhelming most finger sizes. The round shape coupled with a mixed brilliant cut balances the best of both worlds, combining a faceting scheme that encourages lively return of light, with a pavilion design that adds depth and saturation to the color. The excellent polish enhances that light return by ensuring facet junctions are crisp and reflective, which is particularly important in a darker sapphire where surface quality can influence perceived brightness. At one point eight nine carat this sapphire sits in a size range that reads as meaningful and wearable, making it ideal for a central stone in a traditional solitaire, or as a centerpiece framed by shoulders or a halo for added presence.

From a clarity and grading standpoint this sapphire was evaluated as eye clean at eye level, which means there are no inclusions visible to the unaided eye under normal viewing conditions. For colored gemstones and especially for sapphires, eye clean status preserves both aesthetic appeal and value, allowing the stone to show its color evenly and without distractions. The mixed brilliant cut helps mask and distribute minor internal features while maximizing optical performance. The stone has a dark color intensity, which gives it a rich and classic blue tone that many buyers seek in an engagement sapphire. Dark intensity in sapphires can convey a sense of permanence and dignity, while still being vibrant when set and inspected under a range of lighting conditions. The combination of eye clean clarity, a skilled cut, and excellent polish produces a stone that reads as high quality both to the informed collector and to a partner who will wear it every day.

This sapphire has been heat treated, which is a common and widely accepted enhancement in the trade, used to improve color uniformity and remove certain inclusions that do not affect durability.
