Marquise Aquamarine and Diamond Ring in Platinum, 3.77ct

$15,495

A marquise-cut aquamarine set in platinum — icy water blue against bright metal.

Platinum never fades, never needs replating, and holds stones more securely than any gold alloy. The choice when nothing should compromise the piece.

The center stone holds a full 3.77 carats of aquamarine. The marquise cut sits facing forward — light gathers at the apex and disperses through the body of the gem. Accent diamonds totaling 1.80ct catch the light around the center, hand-set with traditional bench work.

Aquamarine reads like still water — calm, cool, clear. Lights up in cool morning light and softens in evening.

Wears every day — clean enough for the office, present enough to be noticed across a room.

Questions, Answered

Before You Decide

What if the size is not right?

One complimentary resize within 60 days of delivery, up to 1.5 sizes, for U.S. orders. Some designs cannot be resized; our atelier will advise. Beyond that window, our atelier still handles resizing for you; speak with a gemologist and we will take care of it. If you are unsure of your size before ordering, start with our ring sizing guide.

When will my ring ship?

Once your order is placed, it passes a final quality inspection and ships fully insured via FedEx Priority Overnight on U.S. orders, signature required.

How do I care for this stone?

Colored gemstones keep their best color with simple habits: remove the ring for heavy work and workouts, clean it with mild soap, lukewarm water, and a soft brush, and have our atelier check the setting periodically. Cleaning and inspection are available through our atelier.

How does platinum hold up to daily wear?

Platinum is a naturally white metal that never fades and never needs replating. With daily wear it develops a soft patina that many owners come to prefer, and it takes a fresh polish beautifully whenever you want the bright finish back.
