1-Carat Lab-Grown Diamond Engagement Rings
For couples seeking timeless elegance with exceptional value, our 1-carat lab-grown diamond engagement rings offer the perfect balance of size, quality, and affordability. These ethically created diamonds are chemically, physically, and optically identical to mined diamonds, but come with significant advantages: they're priced 60-90% lower than their natural counterparts, completely conflict-free, and environmentally responsible.
Each IGI-certified 1-carat diamond in our collection is hand-selected for ideal proportions (Excellent or Ideal cut grades) to maximize brilliance and fire. Whether you prefer the classic sparkle of a round brilliant, the modern appeal of a cushion cut, or the elongated silhouette of an oval diamond, our 1-carat options provide versatile styles to suit every taste.
Beyond their beauty, these diamonds represent a sustainable choice—requiring 85% less water and producing 95% fewer carbon emissions than mined diamonds. Every stone includes a laser inscription matching its IGI certificate, ensuring full traceability from our lab to your jewelry box.
Ideal For: First-time engagements, budget-conscious buyers, or those who appreciate understated luxury.
Is a 1-carat diamond the right size for an engagement ring?
A 1-carat diamond is the most popular choice for engagement rings, offering a perfect balance of presence and wearability. On a size 6 finger, a 1-carat round brilliant measures approximately 6.5mm in diameter —substantial enough to catch the eye while remaining practical for daily wear. Many couples find it strikes the ideal compromise between visual impact and budget considerations.
How much should I expect to pay for a 1-carat lab-grown diamond ring?
Prices for a 1-carat solitaire lab grown diamond ring starts at US$900 at Alya Stone — typically 2 times less than a mined diamond ring. The final cost depends on cut, color, and clarity.
Will people know it’s lab-grown?
No—lab-grown diamonds are chemically, physically and optically identical to mined diamonds. Only an expert with specialized equipment could tell the difference.
Will a 1-carat diamond hold its value over time?
Lab-grown diamonds offer exceptional value from the moment of purchase. Because your initial investment is significantly lower (typically 60-80% less than a comparable natural diamond), your potential depreciation represents far less absolute dollar value. While both lab-grown and natural diamonds experience market depreciation, the key differences are:
- Lower Risk: You're investing substantially less capital upfront compared to natural diamonds of equal quality
- Smaller Absolute Loss: A 50% depreciation on a $2,000 lab-grown diamond means losing $1,000, versus losing $5,000+ on a $10,000 natural diamond*
- Identical Enjoyment: You experience the same beauty, durability and emotional significance regardless of origin
We always recommend choosing a diamond because it speaks to your heart, not as a financial instrument. The true value comes from the lifetime of memories it will represent."
