2.37 Ct. Ruby from Ceylon (Sri Lanka)

This exquisite transparent 2.37 carat oval red ruby from Ceylon Sri Lanka offered by The Natural Ruby Company measures 8.87 by 6.43 by 4.81 mm, and is presented in a mixed brilliant cut with an excellent polish. The stone exhibits vivid color intensity and a clarity graded as very very slightly included at eye level, which means that under normal viewing conditions the stone appears clean and free of significant imperfections. The surface and facet finish are of high standard, and the mixed brilliant pavilion and crown work together to maximize face up color and light return. Enhancement is diffusion treated, a common and stable treatment that intensifies surface near color and should be disclosed for accurate valuation and care.

For an educated buyer, the combination of vivid Ceylon red, transparency, and a meticulous mixed brilliant cut distinguishes this ruby from more common red gems. Compared with garnet and red spinel, this Ceylon ruby offers a deeper and more saturated primary red, with a finer degree of transparency and stronger inertness to color shift under different lighting. Compared with sapphire of the same species, rubies typically command higher attention for intense red hues, and this stone shows the rich pigeon blood tone sought after in high quality rubies. In terms of brilliance, corundum including rubies has a lower refractive index than diamond, therefore it does not produce the same white brilliance and fire that diamonds exhibit, but the mixed brilliant cut on this piece is optimized to produce lively internal red flashes and scintillation that are more color focused, which many collectors and connoisseurs prefer for colored gemstones. The excellent polish ensures crisp facet junctions and superior light performance for its species.

This ruby is an attractive option for a collector or client seeking a high quality, eye clean Ceylon ruby with strong color and fine cut work, and it is well suited to classic settings that showcase color, such as solitaire rings or halo designs with complementary accent stones. Buyers should note the diffusion treatment when considering long term value and care, and The Natural Ruby Company can provide further details on origin verification and treatment documentation upon request, ensuring transparency and confidence in the purchase.
