What does the IGI certification mean for this piece?

This ring carries IGI certification, meaning the diamond has been independently evaluated and documented by the International Gemological Institute. The lab assesses color, cut, clarity, and carat weight, then records the results on a report. That documentation confirms the 5 carat cushion diamond meets the stated grades.

What do the color and clarity grades mean for this diamond?

This diamond holds a G color grade and VS1 clarity. G sits in the near-colorless range, showing no obvious tint to the eye while remaining a step below the top colorless grades. VS1 means any inclusions are very slight and require magnification to locate, so the stone reads clean face-up.

Whose birthstone is Diamond and what month does it represent?

Diamond is the birthstone for April. It is the sole traditional and modern birthstone for that month, with no commonly recognized secondary stone. A diamond ring like this one suits an April birthday directly, though many wear it regardless of month given the stone's broad appeal.

Is 14K or 18K gold better for a diamond ring?

This ring uses 14K yellow gold, which is 58.3 percent pure gold alloyed for added strength, making it well suited to daily wear. 18K gold is 75 percent pure, offering richer color but a slightly softer surface. The better choice depends on your lifestyle and how warm you want the metal to look.

How do I find the right ring size?

Ring size is best confirmed by a local jeweler using a professional sizing set, which gives the most reliable result. At home, you can wrap a strip of paper around the base of your finger, mark where it meets, and measure that length against a printable size chart for an approximate reading.

Can this ring be resized?

This ring can typically be resized by a qualified jeweler, since the solitaire setting and 14K gold band allow adjustment within a reasonable range. Significant size changes may require more work. We recommend confirming your size before ordering and consulting a jeweler for any resizing after delivery.

14K yellow gold ring with one cushion diamond stone in solitaire setting

5 Carat Cushion Lab Grown IGI G/VS1 Diamond Solitaire Ring in 14K Yellow Gold

Name: 5 Carat Cushion Lab Grown IGI G/VS1 Diamond Solitaire Ring in 14K Yellow Gold
Brand: Oath Jewelry
SKU: 66226-3
Availability: InStock

A cushion-cut diamond at 5 carats sits dead center, its softened corners and broad facets spreading light across the full width of the stone. The single-stone setting leaves the diamond fully exposed on a slim 14K yellow gold band, so the warm metal frames the diamond without competing with it. The raised profile keeps the stone clear of clothing, though the height suits considered wear over heavy daily tasks. Every order ships free with a 30-day return policy.

The Meaning

A solitaire diamond has long stood for singular commitment, the lone stone carrying the full weight of meaning without distraction. The cushion cut, one of the oldest faceting styles, traces back to candlelit eras when broad facets were shaped to hold and return soft light. Diamond itself reads as constancy, the hardest natural material set against the softest sentiment.

A stone this size marks a moment meant to be remembered: a proposal, a milestone anniversary, a promise spoken aloud. Worn day after day, it becomes shorthand for the decision behind it, a quiet reminder on the hand of why it was chosen.
