I purchased this from BS Nittele's mail order in February of last year. The purchase price was just under 120,000 yen, but I've lowered the price! I hope to pass it on to someone who will appreciate it. How about it as a Christmas present? The stones are selected, and the final processing and inspection are done in Japan, so you can wear it with confidence. It's a large, single-stone diamond ring. The champagne color is said to suit Japanese skin tones very well. Please refrain from price negotiations. ■ Final Manufacturing Country: Japan ■ Material: Diamond approx. 1.0ct (SI class equivalent / champagne color) Pt999 approx. 1.8g ■ Size: Size 12 Maximum width: approx. 5.5mm Minimum width: approx. 1.3mm A large 1ct diamond ring made with a champagne-colored diamond, popular for its elegant, mature sparkle, and a pure platinum ring frame. The slightly colored, elegant champagne-colored diamond is very popular worldwide because it blends well with the skin, and there are even brands that specialize in champagne-colored diamonds. We are also particular about beauty, and the clarity is equivalent to the SI class. We have carefully selected stones with a high degree of transparency, so you can't easily see inclusions with the naked eye. It has a round brilliant cut that maximizes the brilliance of the diamond. Furthermore, we are particular about the three elements of brilliance that cannot be expressed by the 4Cs of diamond evaluation: "clarity, color, cut, and carat," and we have carefully selected diamonds with beautiful brilliance. ≪Three Elements of Diamond Brilliance≫ ◆ "Brilliance": Light entering the diamond reflects upwards, creating a strong, white sparkle. ◆ "Dispersion (Fire)": Light refracts repeatedly within the diamond, creating a colorful sparkle. ◆ "Scintillation": The contrast of light and the sparkling brilliance that occurs when the diamond is moved. The ring frame that supports the diamond uses high-quality and rare pure platinum. It is a cast construction made by pouring into a mold one by one, resulting in a heavy finish. We have minimized the prongs as much as possible and provided window frames on the sides to allow more light to enter, making the diamond shine even more. It is a product planned by a manufacturer that handles many diamonds, including size and quality. Each one comes with an appraisal certificate.
