AI-assisted summary
Description from the seller
Platinum ring
Pear-cut diamond 0.4 carats
Central stone: a pear-cut diamond (teardrop cut).
Pavement: a triangular pavé on each side composed of small round brilliant-cut diamonds (six on each side, 12 accent stones in total).
Setting: in platinum Pt850 with a ring body featuring a double-groove (ribbon effect).
Hallmarks and interior engravings:
Pt850: platinum alloy graded at 850‰.
Manufacturer's mark: the stylized knot (musubi), a symbol of union typical of Japanese jewelry. a stylized knot with two loops (in Japanese musubi / 結び or chō-musubi / 蝶結び). In Japan, the knot is the traditional symbol of emotional bond (en / 縁), of the promise and lasting union, a recurring emblem on engagement rings (konyaku yubiwa).
0.4 (or 0.41): total diamond weight (central pear stone + pavé), equivalent to about 0.40 carat.
Technical detail: a fine vertical notch is visible on the inside and outside of the bottom of the band, which generally corresponds to a mark from resizing (welding for reduction or enlargement).
This is a vintage Japanese engagement ring with a classic-inspired design from the 1980s–1990s.
The dark line visible inside, (photo on the fingers). A natural inclusion (the most common): If it is a diamond or a natural gemstone, it is very likely a non-crystallized carbon residue or another micro-mineral trapped during formation underground. In gemology, this is called a “pinpoint” or an “inclusion.” It is a natural signature of the stone.
