2.37 Ct. Topaz from Ceylon (Sri Lanka)

This beautiful transparent 2.37 carat greenish blue topaz from Ceylon Sri Lanka is a remarkable example of natural gem quality, weighing a substantial 2.37 carats and measuring 9.20 x 7.13 x 4.85 mm in an elegant oval shape, with a mixed brilliant cut and an excellent polish. The clarity is described as very very slightly included when evaluated at eye level, which means the stone presents with exceptional transparency and only the smallest inclusions that do not detract from its brilliance or face up beauty. The medium intense color intensity gives this topaz a lively greenish blue tone that is neither washed out nor overly saturated, striking a perfect balance for those who want a gem that reads as natural and refined. Importantly, this topaz has no enhancement, a trait that sets it apart from many market alternatives that rely on irradiation or heat treatments to achieve desirable colors. When you choose this gemstone from The Natural Gemstone Company, you are selecting a natural, untreated stone whose provenance from Sri Lanka adds a layer of rarity and desirability, given the countrys long history of producing fine colored gemstones.

When compared to other topaz options commonly available, this Ceylon greenish blue oval stands out in several meaningful ways. Many blue topazes on the market are Swiss blue or London blue varieties whose vivid colors are frequently the result of irradiation and heat treatment, whereas this gem maintains its color naturally, offering a more authentic and investment friendly option. Compared with aquamarine and other light blue stones, this topaz delivers a stronger face up presence for its size, due to the mixed brilliant cut which optimizes light return and scintillation. The clarity grade of very very slightly included at eye level, combined with the excellent polish, means this stone will perform more like higher end goods without the premium price tag seen in some sapphire or aquamarine pieces. The dimensions of 9.20 x 7.13 x 4.85 mm give a generous face up area for 2.37 carats, so you get impressive visual impact in rings, pendants, or bespoke pieces. Value conscious buyers looking for long term satisfaction will appreciate that this topaz needs no enhancement, so its color and character will remain stable and authentic over time.

Under different lighting conditions this greenish blue topaz reveals a subtle and engaging personality, shifting emphasis between blue and green tones while maintaining lively brilliance. In bright daylight and direct sunlight the mixed brilliant cut excels, producing lively white sparkle and a clear, clean blue with a whisper of green, the medium intense color appearing fresh and vibrant against the high quantity of natural light. Under cool fluorescent or office LED lighting the stone leans more toward pure blue, with crisp internal reflections and a slightly more clinical, icy appearance that works beautifully for modern, minimalist settings. Under warm incandescent lighting or candlelight the greenish component becomes more apparent, giving the gem a softer aqua or oceanic hue that feels romantically warm, and the excellent polish helps each facet catch the softer rays to create a gentle scintillation. The mixed brilliant cut means that the crown delivers bright flashes and the pavilion returns light efficiently, so whether the environment is harsh or subdued, this topaz retains a lively play of light rather than fading into a flat color.

For practical use and long term enjoyment this topaz offers both versatility and enduring appeal. Its oval shape and measurements make it especially suitable for classic solitaire rings, halo settings that emphasize color while protecting edges, elegant pendants that show off the face up color, and bespoke pieces where the gem is the centerpiece. Compared to similar sized aquamarines and treated topazes, this stone offers better color authenticity and a clearer appearance for daily wear, while still being comfortable to set for occasional dress wear or everyday use with sensible care. We recommend secure settings to protect the girdle from knocks, and routine cleaning with mild soap and warm water to preserve its excellent polish and brilliance. As with all fine gemstones, avoid harsh chemicals and extreme heat sources to keep the color and clarity pristine. At The Natural Gemstone Company we pride ourselves on sourcing and presenting natural, untreated gems with transparent origin information, and this Sri Lankan greenish blue topaz is a perfect example of that commitment. Its combination of honest color, fine clarity, expert mix brilliant cutting, and excellent polish makes it a superior choice for buyers who want a beautiful, authentic gem that performs consistently under varied lighting, while also representing excellent value relative to treated alternatives.
