Our take on the Tiffany & Co. Platinum Diamond Solitaire Engagement Ring

A pre-owned Tiffany & Co. solitaire engagement ring in platinum, set with one round brilliant cut diamond. It is a size 5 1/4 estate piece, inspected and authenticated by Long's Jewelers and sold with its original box. At $1,480 at Long's Jewelers as of November 4, 2026, it is the only new-condition listing tracked, so there is no recent price range to compare against. Buyers get the Tiffany name and setting at a fraction of new retail, but the diamond's carat, color and clarity are not stated.

Questions and answers

Is this ring worth $1,480?
That depends on the diamond. A new Tiffany platinum solitaire typically runs several thousand dollars, so $1,480 is low for the brand. Ask for carat, color and clarity before deciding; those set the real value.
What are the diamond's specs?
The listing gives only one round brilliant cut diamond. Carat weight, color and clarity are not stated, so request them from Long's Jewelers before buying.
Can it be resized?
It is a size 5 1/4. A jeweler can usually resize a platinum solitaire band, but sizing down more than a little can disturb the setting. Confirm with the seller first.
Is it really a Tiffany ring?
Long's Jewelers says its in-house jewelers and authenticators inspected it. Ask for photos of the Tiffany hallmark and any paperwork before you buy.
What comes in the box?
The original Tiffany box is included. No diamond certificate or appraisal is mentioned, so ask whether any documents come with it.
When is the best time to buy?
With only one store listing it, there is no price history to time. Compare against other pre-owned Tiffany solitaires and buy when the specs justify the price.
Where is the Tiffany & Co. Platinum Diamond Solitaire Engagement Ring cheapest?
At Long's Jewelers, for $1,480.00, 30% off, as of our latest check.
