I'm not sure if others agree, but this kind of detailed, romanticized description is what appeals to me (see below). You wouldn't have to make yours as long, but maybe take some inspiration from it:
"This is a truly stunning Art Deco platinum diamond engagement ring with very fine quality diamonds. Found together at auction with it's wedding band inscribed from 1926 (also available in my shop), this ring will be accompanied by it's independant appraisal done by a conservative GIA gemologist and certified appraiser. (the total replacement value of this ring with it's white gold diamond band, available seperately, is $6,700.00.)
Crafted of solid platinum, this ring features 29 super bright and clean diamonds in a striking, very Deco geometric design with a total estimated carat weight of 1.25 carats. (please note that there are *no* dark areas in these diamonds...any dark areas in my photos are just reflections of these very white and fiery stones!)
Measuring approximately 5.76 mm in diameter, the .65 carat center stone is a transitional cut diamond with a small open culet and all the fire I love to see in these hard to find old cut diamonds. (transitional cuts are the step between European cuts and today's modern brilliant cut diamonds, so they are a type of brilliant cut diamond, but usually have a small to tiny culet and are extremely fiery. They were only made for a very short time and so are difficult to find nowadays.) This diamond has been judged to have I color (in the near-colorless range), with VS1 clarity and no fluorescence. It's in wonderful original condition and is held in place with four double prong settings that make it look even a bit larger than it already is.
On either side of the fiery center diamond, are two bright and clear straight baguette cut diamonds. Channel set, they create an Art Deco step design, with the larger diamond closest to the center stone, and the smaller baguettes in the lower step on each side. These diamonds measure approximately 3.2 x 1.7 mm to 3.5 x 1.70 mm, (estimated at approximately .36 carats total weight) and have been graded to have G-H color and VS1 to VS2 clarity. Again, these stones are in great original condition.
Twenty-two sparkly single cut diamonds are bead set along the outer rails of the ring, 11 to each side, following the elegantly curving profile of the ring. With two more gracing the shoulders, one to each side. This gives the ring great sparkle from every angle and adds to the substantial presence on the hand. Measuring approximately 1.5 mm in diameter each, these small diamonds are G-H color with VS1 to VS2 clarity, and have an estimated total carat weight of .24 carats, for a total estimated 1.25 carats in the ring.
Substantial and striking without being at all garish, this ring has a beautiful and prominant presence on the hand. The face measures approxiately 8 x 16.3 with a rise off the finger of approximately 4.8 mm. It's comfortable on the finger and it's modest rise makes it very suitable for every day wear.
Simple and elegant, the band is still in good, strong condition. Inside it retains a clear maker's mark of "G.M. Co" as well as a mark for 10% iridium platinum. (This is a good quality platinum allloy used frequently during the Art Deco era. Iridium is a member of the precious platinum family and was added to platinum to increase it's strength, hardness and whiteness of color. It's still used occasionally nowadays by a few high end makers, and it's an alloy I am always pleased to find since it tends to stand up to time and wear so nicely.) The total weight of the ring is 3.90 grams.
Size 5.25 on my ring mandrel, this ring could be sized within reason by a good jeweler who is experienced in working with platinum. ** Please read my policies page for more information regarding sizing and feel free to message me with any questions or to obtain a quote from my trusted bench jeweler. This ring will be shipped via Express insured mail within the US, which is usually 2 days shipping time.
A very fine quality and strking 1920's Art Deco engagement ring...ready to become your family's heirloom..."
You could highlight that a solitaire is a classic and traditional style, that she will love for years to come. That solitaire is the perfect setting to feature a high-quality stone such as this. Etc. etc.
