Three Stone Bluish Green Tourmaline Ring 1.56 Ct., 18K White Gold

This ring from The Natural Gemstone Company centers on a transparent bluish green tourmaline weighing 1.56 carat, cut to a cushion shape with a mixed brilliant faceting style. The stone measures 7.48 by 6.54 by 4.77 millimeters, displaying intense color saturation and an excellent polish that promotes lively light return and deep color depth. The tourmaline is graded as very slightly included evaluated at eye level, which for an experienced buyer indicates minor inclusions that do not materially detract from visual performance or color intensity when the stone is mounted. Flanking the center are white asscher octagon shaped lab grown diamonds with a combined weight of approximately 0.46 carats, clarity grades in the VS1 and VS2 range, and an F color grade, placed to enhance the central stone without overpowering it. The entire composition is crafted in platinum 950, a dense and highly durable precious metal that secures the settings and maintains a bright white backdrop to emphasize the green tones of the tourmaline and the near colorless quality of the diamonds.

For an educated buyer assessing value, several technical strengths are immediately evident. The tourmaline originates from Brazil, a location renowned for producing saturated, gem quality green and bluish green tourmalines, and provenance from this source supports the stone character and market perception. The intense saturation of color is the primary driver of desirability for this hue, as tourmaline value rises with richer, evenly distributed coloration and strong saturation without excessive darkness. The clarity grade very slightly included evaluated at eye level means the stone is effectively eye clean in most viewing scenarios, and its excellent polish ensures maximum brilliance from the mixed brilliant cut. The cushion shape with mixed brilliant faceting balances focal depth with surface scintillation, making the stone read larger than its carat weight might suggest. The lab grown asscher diamonds add refined contrast through step and octagonal geometry, their VS clarity grades assuring minimal to no visible inclusions, and F color providing high whiteness that complements platinum. Using platinum 950 rather than a lower purity metal is a quality signal for longevity and for maintaining prong integrity and mirror like finishes over years of wear.

Durability considerations are essential for daily wear, and this ring has been designed with those factors in mind. On the Mohs hardness scale, tourmaline typically registers around 7 to 7.5, while diamond is a 10, so the side diamonds will resist scratching and abrasion far better than the center tourmaline. Platinum 950 offers exceptional toughness and will protect the stones with robust prongs and a stable setting platform. Tourmaline does not have perfect cleavage like some gemstones, but due to its characteristic crystal structure and possible internal features, it can be vulnerable to sharp blows and to surface abrasion where inclusions reach near the surface. The very slightly included grade reduces that risk compared to more heavily included material, but care remains prudent. For everyday use this ring is well suited, provided basic precautions are observed, such as removing the ring for heavy manual work, sports, or tasks that could subject the stone to impact. Routine maintenance will maximize longevity, including gentle cleaning with warm soapy water and a soft brush, periodic professional inspections to check prong security, and gentle polishing of the platinum if desired. Ultrasonic cleaning is generally safe for well seated, low inclusion tourmaline, but if there are internal fractures or reaching inclusions it is best to consult our gem care team at The Natural Gemstone Company before using aggressive methods.

Taken together, these attributes make this platinum 950 ring an intelligent choice for a buyer seeking a statement center stone with reliable performance characteristics. The 1.56 carat bluish green tourmaline offers a rare and desirable color presence enhanced by a mixed brilliant cushion cut and excellent polish. The eye level clarity of very slightly included preserves visual purity while the lab grown asscher diamonds provide high quality contrast in VS clarity and F color. The platinum 950 mounting combines security with an enduring white metal finish that will maintain its appearance for decades with proper care. When durability, aesthetic quality, and gemological integrity are priorities, this ring represents a well balanced option, and The Natural Gemstone Company can provide additional images, testing reports, or maintenance advice to support a confident purchase.
