Astoria GIA 1.00 old mine cut diamond 18k gold engagement ring - T&H Exclusive

$ 6,500
A GIA-graded 1.00 carat old mine cut diamond is held in four double claws on a slim, polished 18k yellow gold band.
Certificates:
An old mine cut diamond of a full carat sits in four slim, double claws on a plain 18k yellow gold band, a classic solitaire with the character of an antique stone. The cushion-shaped stone has large, rounded facets that give it a soft, glittering sparkle, quite different from the sharper flash of a modern cut. It weighs 1.00 carat in I color and SI1 clarity and is accompanied by GIA #6531679396. The simple band is polished and gently tapered, with no extras to compete with the diamond. Crafted in 18k yellow gold and hallmarked with a purity mark, the ring weighs 4.30 grams. Circa 2026, it suits someone who wants a timeless solitaire engagement ring with a little more history and personality than a standard round brilliant.

Beyond obsessed

I'll just start by saying that every piece of vintage jewelry in this shop is more beautiful than any other I saw in all of LA. Not only do I absolutely adore my ring, I had an amazing experience here as well. Basically the dream situation for a newly engaged gal!

For the past four years we have only used Trumpet & Horn for fine jewelry purchases. The team at Trumpet & Horn go above and beyond to make sure that each detail is classy and beautiful. I have worn my engagement set every day for nearing four years.
