Why Choose Lab-Grown?
- 💰 Lower prices (up to 60% less than mined)
- 🌱 Eco-conscious and conflict-free
- 🔍 Often cleaner (higher clarity for lower cost)

🔍 1.51 Carat F‑Color VS1 Clarity Round Brilliant Diamond (Excellent Cut)
💎 Key Specifications
- Carat Weight: 1.51 ct — a luxurious size that balances presence and wearability, typically commanding a higher price per carat due to rarity
- Color Grade: F — in the upper “colorless” tier (D–F), so virtually no yellow or body tint visible to the naked eye; F remains highly sought after for its pure, bright appearance
- Clarity Grade: VS1 — “Very Slightly Included that are difficult to detect under 10× magnification”; eye‑clean for most observers while offering excellent value-to-clarity ratio
- Cut Grade: Excellent — indicative of outstanding proportions and symmetry, critical to maximizing sparkle and light return; only a small fraction of diamonds reach this level
✨ Performance Highlights
- Light and Brilliance: With an Excellent cut grade, this diamond is expertly faceted to harness maximum fire, scintillation, and brilliance. Ideal cut diamonds are known to appear larger than their measured size due to optimized light performance and face-up spread
- Color-Neutral Visual Appeal: The F color grade means this diamond is effectively colorless, maintaining a crisp, white visual appeal even when set in white metal such as platinum or white gold
- Clarity and Cleanliness: VS1 clarity offers exceptional visual clarity without the premium price tag of VVS or IF grades. Inclusions (if any) are subtle and under 10× magnification only, making the stone eye‑clean in most lighting conditions
🧠 Why It Stands Out
1. GIA Certification & Conflict‑Free Sourcing
This diamond is certified by GIA (Gemological Institute of America), ensuring reliable grading across all 4Cs. James Allen guarantees conflict‑free sourcing, offering transparency and ethical assurance.
2. 360° HD + 40× Magnification
James Allen’s platform lets buyers inspect every nuance of the diamond through high-definition 360° videos and up to 40× magnification. This level of visibility helps ensure confidence in the quality before purchase.
3. Excellent Value Proposition
Combining a strong cut, high color, and solid clarity in the 1.5 ct range delivers tremendous sparkle per dollar. This blend is especially prized by savvy buyers aiming to maximize visual impact without overspending.
🎯 Ideal For…
- Engagement rings when you want both size and sparkle.
- Solitaire, halo, or three‑stone settings, where a round brilliant centerpiece shines.
- Buyers seeking eye‑clean brilliance with high color standard yet excellent value.
✅ Final Take
This 1.51 ct F‑VS1 round diamond with Excellent cut is a stellar pick for anyone seeking a large, brilliant, colorless, and eye-clean diamond. Its GIA certification, top-tier cut, and ethical sourcing from James Allen offer reassurance and premium visual performance. Whether set in a solitaire, halo, or custom design, it promises a classic sparkle with exceptional value.
🔍 1.79 Carat E‑Color VS1 Clarity Round Brilliant Diamond (Ideal Cut)
💎 Key Specifications
- Carat Weight: 1.79 ct — presents a substantial size with excellent visual impact and presence in engagement settings.
- Color Grade: E — in the upper “colorless” range (D–F), offering crisp, white appearance with no visible warmth or body tint.
- Clarity Grade: VS1 — “Very Slightly Included”; eye‑clean in most cases and offers a strong balance between clarity and value.
- Cut Grade: Ideal (IGI standard) — among the top cuts available; ensures maximum brilliance, fire, and scintillation. Only a small percentage of diamonds meet this level of optical precision and light performance
✨ Performance Highlights
- Exceptional Light Return: The Ideal cut facilitates superb balance of brilliance and fire. This cut tends to make the diamond appear larger and more luminous compared to typical cuts at the same weight.
- Color Neutrality: The E color ensures the diamond remains visually crisp and white, showing minimal color even when viewed under white or platinum settings.
- Clarity Strength: VS1 clarity practically guarantees an eye-clean diamond, minimizing visible flaws while avoiding the premium price associated with VVS or IF grades.
🧠 What Makes It Stand Out
1. Certification & Cut Precision
This diamond is IGI‑certified with an Ideal‑cut grade—the IGI equivalent of excellent or top-tier optical performance. It meets strict symmetry and polish standards, maximizing light delivery from every facet angle.
2. Ethical Sourcing & Visual Inspection Tools
James Allen guarantees conflict-free sourcing and provides 360° HD video and up to 40× magnification for each diamond. These tools allow for in‑depth visual inspection before purchasing, adding transparency and buyer confidence.
3. Premium Carat & Quality Combination
At 1.79 ct with E‑color and Ideal cut, this diamond hits a premium combination: less accessible due to rarity of high color and size, while still being ethically sourced and beautifully proportioned.
🎯 Ideal For…
- Those who prioritize size and sparkle, especially in solitaire or halo engagement ring settings.
- Buyers seeking colorless appearance (E grade) while maximizing visual fire with an Ideal cut.
- Those who want excellent clarity without paying for VVS or higher grades—VS1 delivers virtually identical performance to the eye.
✅ Final Take
The 1.79 ct E‑VS1 Ideal cut round diamond is a top-tier choice for anyone seeking maximum sparkle, color purity, and eye‑clean clarity in a luxurious weight. It pairs beautifully with minimalist settings or accent stones that allow its brilliance to take center stage. GIA-level color and clarity combined with Ideal cut performance and viewing transparency make it a compelling selection.

🔍 1.91 Carat F‑Color VS2 Clarity Round Brilliant Diamond (Excellent Cut)
💎 Key Specifications
- Carat Weight: 1.91 ct — a bold and impressive size that delivers strong wrist presence and visual impact in engagement rings.
- Color Grade: F — in the colorless tier (D–F); this stone will appear crisp and white with no perceptible warmth or tint to the unaided eye.
- Clarity Grade: VS2 — “Very Slightly Included 2”; typically still eye‑clean in most circumstances, though inclusions may be detectable under magnification, especially given the larger size.
- Cut Grade: Excellent — ensures outstanding light performance and symmetry; only a minority of diamonds achieve this level of craftsmanship, translating to superior sparkle and brilliance.
✨ Performance Highlights
- Light Performance: With an Excellent cut grade, this diamond has the ideal facet structure to maximize brilliance, fire, and scintillation, making it appear larger and more luminous on the finger.
- Color Appeal: As an F color, the diamond will appear vividly white with no detectable hue, even when set in platinum or white gold—ideal for those seeking a high-end, clean aesthetic.
- Clarity & Value: VS2 clarity offers a good balance between eye-clean appearance and cost-efficiency. At 1.91 ct, it’s especially important to inspect inclusion placement, since larger diamonds can make inclusions more visible. Still, most VS2 stones remain eye-clean without magnification.
🧠 What Makes It Stand Out
1. Precision & Sparkle from Excellent Cut
James Allen’s Excellent cut diamonds are engineered to meet stringent proportions for optimal light reflection and visual performance. With around 58 facets, this classic round shape delivers unmatched radiance on nearly any setting.
2. Ethical Sourcing & Visual Transparency
James Allen guarantees conflict‑free sourcing and provides access to high-definition 360° video and up to 40× magnification. This lets shoppers inspect every detail—especially inclusion location and light behavior—before purchasing.
3. High‑Impact Size at Smart Value
Nearly 2 ct with F color and Excellent cut offers exceptional presence and brilliance without the high premiums of higher clarity grades like VVS or IF. VS2 still delivers strong visual performance for most buyers who aren’t chasing absolute perfection.
🎯 Ideal For…
- Statement solitaire rings, halo settings, or three-stone designs where the diamond’s size and sparkle take center stage.
- Buyers who prioritize white color appearance and high brilliance, and who are comfortable with VS2 clarity.
- Those who prefer to allocate budget into cut quality and carat weight rather than ultra-high clarity grades.
✅ Final Take
The 1.91 ct F‑color VS2 Excellent cut round diamond strikes a compelling balance: high carat weight and colorless visual appeal with excellent cut performance—all at a cost-effective clarity level. Perfect for showcasing brilliance in multiple ring settings, it’s an outstanding choice for those wanting impact without overpaying.
💡 Tips Before Buying
- Examine the full grading report: check table %, depth %, symmetry, polish, and fluorescence details.
- Use James Allen’s 360° HD video and high magnification tools to assess inclusion visibility and cut performance firsthand.
- Consider a Real‑Time Diamond Inspection session with a certified gemologist to discuss eye‑cleanliness and overall impression.
- Compare side-by-side with VS1 or E color stones to evaluate sight differences vs. price trade-offs.
🔍 1.90 Carat E‑Color VS2 Clarity Round Brilliant Diamond (Ideal Cut)
💎 Key Specifications
- Carat Weight: Approx. 1.90 ct — offering commanding wrist presence and luxurious visual size in engagement settings. Larger high‑quality stones like this are increasingly rare, giving premium resale and visual impact value.
- Color Grade: E — in the “colorless” range (D‑F), this grade ensures minimal to no warm tint visible to the unaided eye—even in platinum or white‑gold settings.
- Clarity Grade: VS2 — “Very Slightly Included 2.” Inclusions are typically hard to spot under 10× magnification, and most VS2 diamonds of this weight remain eye‑clean.
- Cut Grade: Ideal — the highest proportioned cut under IGI/GIA standards for maximizing brilliance and fire. Only about 3% of stones meet this level.
✨ Performance Highlights
🔍 Light Return & Brilliance
With an Ideal cut, this round brilliant diamond is precisely faceted to strategically reflect and disperse light—resulting in outstanding sparkle, depth, and face‑up brightness. Well‑cut stones also tend to look larger than their carat weight suggests.
🎨 Color Purity
E color guarantees a crisp, white appearance with virtually no visible warmth. This makes it versatile across metal choices, particularly enhancing its presence in platinum or white gold.
👁️ Clarity & Visual Appeal
VS2 clarity maintains an excellent balance of internal cleanliness and cost-effectiveness. Inclusions—if any—should not be visible to the naked eye, although at larger sizes it’s smart to inspect via James Allen’s magnified imagery.
🔭 What Makes This Diamond Stand Out
- Size Meets Sparkle
The near‑2 ct weight commands attention. Combining that with an Ideal cut delivers both size and brilliance in one. Larger diamonds with great optics are rare and highly valued. - High-End Visual Purity
As an E-colored diamond, you get colorless quality without the steeper price tag of D-grade stones—an excellent value for a crisp, white look. - Ethical Transparency & Viewing Tools
James Allen guarantees conflict-free sourcing. Their platform includes 360° HD video and up to 40× magnification, allowing you to evaluate cut precision and inclusion placement before buying.
🎯 Ideal For…
- Engagement rings—particularly solitaire, halo, or three-stone settings—where the diamond’s center stage brilliance will be unmatched.
- Buyers aiming to maximize cut and face-up size while maintaining a colorless presentation and strong visual clarity.
- Those seeking a smart balance between clarity and cost.
✅ Final Take
The 1.90 ct E‑color VS2 Ideal cut round represents a luxurious, visually striking diamond choice—pairing size, crisp color, eye‑clean clarity, and top-tier light performance in one gem.
🔍 1.61 Carat D‑Color VVS2 Clarity Round Brilliant Diamond (Ideal Cut)
💎 Key Specifications
- Carat Weight: ~1.61 ct — a substantial size offering luxurious presence in an engagement ring while remaining wearable and elegant.
- Color Grade: D — the highest grade on the GIA color scale, virtually colorless even under magnification; considered the pinnacle of visual purity.
- Clarity Grade: VVS2 — “Very, Very Slightly Included 2,” meaning inclusions are extremely minor and typically only visible under high magnification; this grade ensures near-flawless appearance to the naked eye.
- Cut Grade: Ideal — this round brilliant meets the top standards (by IGI/GIA) for optimal light return; such cuts are rare but deliver exceptional brilliance and fire.

✨ Performance Highlights
- Exceptional Brilliance: The Ideal cut faceting is engineered to maximize light return, yielding outstanding sparkle, scintillation, and perceived size. A well-cut round diamond often appears larger face-up than its carat weight suggests.

- Near-Flawless Clarity: VVS2 clarity ensures an ultra-clean appearance, with inclusions detectable only under magnification and not visible to the naked eye. This clarity grade pairs beautifully with a diamond of this cut and color.
🧠 What Makes It Stand Out
- Flagship Quality Visual 4Cs
Combining D color, VVS2 clarity, and Ideal cut in a ~1.6 ct diamond places it among the top 1–3% of all diamonds faceted for maximum light performance. - Ethical Sourcing & Inspection Tools
James Allen offers conflict-free sourcing and visualization tools like 360° HD zoom and 40× magnification, allowing buyers to scrutinize inclusion location and light performance before purchase. - Perfect Balance of Beauty and Value
For buyers seeking uncompromised optical performance without paying for >2 ct stones, this diamond offers superb brilliance with premium 4C quality in a compelling size and price category.
🎯 Ideal For…
- A truly luxury-caliber solitaire or halo engagement ring where every aspect—size, brightness, whiteness, clarity—is uncompromised.
- Those who want a diamond with maximum white appearance, gleaming from every angle and under any light.
- Individuals seeking near-perfect clarity without the steep premiums of IF or FL grades—VVS2 is visually indistinguishable in this application.
✅ Final Take
This 1.61 ct D-color VVS2 clarity Ideal-cut round diamond represents pinnacle quality: top-tier color, near-flawless clarity, and precision cut in one gem. It’s ideal for those demanding brilliance and purity in a stunning—and ethically sourced—package.
🔍 1.93 Carat F‑Color VS1 Clarity Round Brilliant Diamond (Excellent Cut)
