Tension set rings are especially desirable because they create the striking illusion of a floating stone, making the diamond the unmistakable focal point while showcasing the engineering of the setting itself. The 0.603ct diamond gives the ring refined brilliance, while the substantial platinum construction adds both visual weight and a sense of serious craftsmanship that collectors appreciate in signed modern jewelry. What makes this piece particularly special is its maker and date, as Tokyo Matsuda designs carry strong design interest and the Ubiwa model reflects a more architectural, collector-oriented approach than a standard solitaire. Bold, sculptural, and unmistakably modern, this is a standout platinum ring with strong designer appeal and lasting visual impact.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eWeight: 24.7 Grams\u003c\/div\u003e\u003cdiv\u003eStone: H VS1 0.60ct Diamond\u003c\/div\u003e\u003cdiv\u003eMeasurements: 25.4 x 6.9 x 24.22mm\u003c\/div\u003e\u003cdiv\u003eSize: 7\u003c\/div\u003e\u003cdiv\u003eHallmark: Tokyo Matsuda, Ubiwa, 2001\u003c\/div\u003e\u003cdiv\u003eMetal: Platinum 900\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eItem #: BR-1913-060326-18\u003c\/div\u003e","brand":"Blue Ribbon Rarities","offers":[{"title":"Default Title","offer_id":41160199503944,"sku":"BR-1913-060326-18","price":3495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2223\/5059\/files\/IMG_2990_3657383.jpg?v=1781478391","url":"https:\/\/www.blueribbonrarities.com\/products\/tokyo-matsuda-ubiwa-platinum-0-60ct-diamond-tension-set-ring","provider":"Blue Ribbon Rarities","version":"1.0","type":"link"}
