Crescent Moon Ruby Engagement Ring Set in 14K Solid Yellow Gold
This crescent moon ruby ring set centers a marquise-cut lab-grown ruby in vivid, passionate red, cradled in a delicate crescent moon design and matched to a coordinating band. A celestial two-piece set where a rich red center meets moonlit romance — now offered in your choice of 10K, 14K, or 18K solid gold. Ruby is July's birthstone.
The ruby
The marquise center is a genuine lab-grown ruby — real ruby (corundum) with the same chemistry, hardness (9 Mohs), and vivid red as a mined stone, grown sustainably with a traceable origin. Ruby has symbolized love, passion, and vitality for centuries, and it's July's birthstone. Our ruby meaning guide and July birthstone guide explore its history and lore.
A two-piece set
Engagement Ring
Marquise lab-grown ruby center (5×10mm, ~1.2ct) cradled in a crescent moon setting with moissanite accents.

Choose your metal & karat
This set is made to order in solid gold — never plating or vermeil over a base metal — so the color runs all the way through and will never wear off or turn your skin green. Warm gold glows against the ruby's red. Choose the karat and color that suits you from the drop-down menu:
10K Gold
The most hard-wearing and budget-friendly option, with a slightly paler tone and excellent everyday durability.
14K Gold
Our most popular choice — the ideal balance of rich color, durability, and value for daily wear.
18K Gold
The richest, most saturated gold in a premium alloy with a luxurious weight.
White & Rose
Prefer a cooler or blush look? White and rose gold are available in every karat too — just select above.
