11.68 Ct. Yellowish Green Prasiolite from Brazil

One beautiful transparent 11.68 carat asscher octagon shape yellowish green prasiolite, dimensions 13.70 by 13.59 by 10.01 mm, offers a rare and memorable statement that outshines many other green gemstones on the market. This gem from Brazil displays an intense color intensity that is remarkably even across the pavilion and crown, and it benefits from an excellent polish that allows each facet to catch the light with crisp clarity. At The Natural Gemstone Company we see many green stones, but few combine this particular size, clarity, and cut with such lively, saturated color. Where peridot of similar hue often shows more visible inclusions and emerald frequently commands a much higher investment while retaining natural fissures, this prasiolite presents a clean, luminous alternative that feels both luxe and approachable. Its 11.68 carat presence gives it runway worthy scale without compromising wearable elegance, and its transparent nature makes it ideal for designs that require both light and depth.

The asscher cut paired with an octagon outline is a design choice that amplifies the gem's strengths and differentiates it from the more commonly seen round brilliant and oval cuts. The step facets of the asscher cut produce a hall of mirrors effect, offering broad flashes of light and a geometric clarity that invites inspection. In this stone the cut has been executed with precision, resulting in excellent polish and a symmetry that enhances the intense yellowish green hue. Clarity is graded very slightly included, evaluated at eye level, meaning the eye sees a nearly clean field which preserves sparkle and visual purity. Compared to some green tourmalines that suffer from color zoning, or to tinted quartz that lacks depth, this Brazilian prasiolite carries a steady, saturated tone that reads as refined and rare. It has been heat treated to develop its enticing green, a standard and stable enhancement for prasiolite that yields long lasting color when cared for properly.

When advising customers who are choosing a gift that will truly impress, I often contrast this prasiolite with sapphires, emeralds, and peridots. Green sapphire and emerald may carry exceptional prestige, yet they come with trade offs, emeralds in their natural state usually require additional care because of internal fissures and often need stabilization, while green sapphires are significantly more costly and may not provide the same warm yellowish green that delights the eye here. Peridot, while affordable, generally appears smaller at a given carat weight due to refractive properties and typically shows more inclusions. This prasiolite occupies a sweet spot in the market, offering dramatic visual impact, considerable size, clean eye appeal, and a color that feels fresh and contemporary. For someone seeking a meaningful gift that is both distinctive and wearable, this gem serves as a thoughtful alternative to traditional green stones, delivering statement making presence without the premiums attached to rare emeralds or the mass market look of common green quartz.

Presented as a striking gift, an 11.68 carat asscher octagon prasiolite from The Natural Gemstone Company suggests intention and careful taste, perfect for anniversaries, milestone birthdays, or a special engagement choice that favors individuality. Its geometry flatters both modern and vintage inspired settings, translating beautifully into a ring, pendant, or a dramatic cocktail piece. For daily wear it offers respectable durability as a gem in the quartz family, and routine care with gentle cleaning using mild soap and warm water will preserve its surface and shine. Avoid prolonged exposure to extreme heat and harsh chemical cleaners to maintain the intensity of color over time. Our recommendation for presentation is to showcase the asscher facets in an open head setting that allows light to enter freely, emphasizing the hall of mirrors effect that makes this gem so compelling. Choosing this prasiolite means gifting a distinctive, polished, and impressive stone that stands apart from other market options, and at The Natural Gemstone Company we are proud to offer such a remarkable Brazilian gem to customers who want something memorable and exceptional.
