IGI Certified Lab Grown Marquise 5 Ct F-G Color, VVS-VS Clarity
This IGI-certified lab-grown loose diamond offers a 5 carat marquise cut with color grades F-G and clarity in the VVS-VS range. The precision cut is designed to maximize brilliance while maintaining a more accessible price point than many mined stones. The lab-grown process—whether HPHT or CVD—produces a diamond with identical chemical and physical properties to mined diamonds, but with a significantly smaller carbon footprint. This option is ideal for designers crafting rings, earrings, pendants, or custom pieces for weddings, anniversaries, or milestone celebrations.
Key considerations include ensuring the cut quality is balanced with color and clarity to achieve maximum sparkle in various lighting. A 5-carat marquise stone can appear larger due to its elongated shape, and a high-quality setting will protect the long points, preserving symmetry and brilliance over time. For makers, this stone provides a reliable canvas for intricate prong or bezel designs that showcase the marquise silhouette.
IGI 5 Ct Marquise Lab-Grown Diamond D-E Color, VVS-VS Clarity
This option features a D-E color grade with VVS-VS clarity, suitable for designers who want near-colorless shine with minimal inclusions. Like the F-G option above, these stones are IGI-certified and lab-grown, aligning with sustainable jewelry principles. Compared with mid-range colors, D-E can slightly intensify fire and sparkle in certain lighting, depending on cut fidelity. The 5-carat marquise carat weight yields a dramatic profile, so careful consideration of proportion and girdle thickness helps ensure a balanced reveal from every angle. The listing emphasizes suitability for weddings, engagements, or anniversary pieces that demand a standout center stone.
Fascinating Diamonds 5 Carat Lab-Grown Marquise Diamond, D-E Color
Fascinating Diamonds presents an IGI-certified, 5-carat marquise with D-E color and VVS-VS clarity, highlighting near-colorless brilliance and minimal inclusions. IGI certification provides assurance of cut, color, and carat accuracy, which is crucial when working with large stones. The model emphasizes responsible supply and the same physical properties as mined diamonds, offering significant cost-efficiency and ecological advantages. Designers and buyers may compare this option against other high-clarity stones to select a balance between color perception and sparkle in low-light or bright environments.
Friendly Diamonds 5 Carat Marquise Pendant Necklace
This piece centers a 5-carat marquise lab-grown diamond in a platinum-toned pendant, offering VS clarity with E-F color in a secure diagonal “V” prong setting. The design emphasizes a chic, wardrobe-friendly aesthetic suitable for weddings or special occasions. The pendant includes an 18-inch chain, pairing utility with elegance. While primarily a jewelry piece rather than a loose stone, it demonstrates how large lab-grown marquise diamonds translate into wearable, symbolic gifts. When evaluating such pendants, consider chain length, mounting protection, and compatibility with earrings or rings to create a cohesive set.
Houston Diamond District 1-5 Carat Lab-Grown Solitaire Diamond Ring
This offering showcases a lab-grown, IGI-certified diamond in a traditional solitaire setting, advertised as 0.75 carat or up to 5 carats within a single collection. The ring emphasizes a classic design with color grades E-F and clarity around VS2-SI1, delivering refined sparkle and a secure, durable mounting. For buyers, this option illustrates how a large marquise-looking center can be integrated into an everyday ring while retaining the dramatic impact of a 5-carat stone in a refined, timeless silhouette. Return policies and certification standards are highlighted to help ensure a confident purchase of a standout piece.
Gem Stone King 5 Ct IGI Lab Grown Diamond Ring, Marquise Shape

Color grades E-F and clarity VS1-VS2 align with high-quality visuals and strong sparkle, making it a compelling option for engagement or special occasions. The two-tone setting adds warmth and a modern twist to a classic shape, appealing to buyers seeking a contemporary aesthetic without compromising on the diamond’s brilliance. Certification and setting design are emphasized as critical factors for ensuring authenticity and longevity in daily wear.
Buying Guide: Key Considerations For 5 Carat Marquise Diamonds
When selecting a 5-carat marquise diamond, buyers should weigh several factors to optimize value, appearance, and longevity. This guide compares essentials to help make informed choices.
- Color and clarity balance: For a marquise of this size, near-colorless to colorless options (D-F or E-F) with VVS-VS clarity provide exceptional sparkle. Slightly lower colors can appear more yellow in large stones if cut quality is not optimized.
- Cut quality and proportion: The elongated shape can accentuate length, so depth, table width, and girdle thickness must be well-controlled to maximize light performance and minimize bowing or bow-tie effects.
- Lab-grown vs. mined: Lab-grown diamonds offer identical physical properties with lower cost and carbon footprint. Certification (IGI, in this case) confirms color, clarity, and carat accuracy and is essential for transparency.
- Setting and protection: A marquise’s pointed ends are vulnerable to chipping. Secure prongs or bezel settings, plus a robust mounting, help preserve brilliance over time.
- Certification and origin: Reputable labs (IGI, etc.) provide certificates that validate cut, color, and carat. Cross-check with supplier warranties and return policies to ensure peace of mind.
- Styling versatility: A 5-carat marquise center works well in solitaire rings, halo designs, and pendant pieces. Consider complementary side stones or accent shapes that enhance the marquise silhouette without overwhelming it.
- Budget and value: Lab-grown stones at this weight offer substantial savings over mined alternatives, enabling premium settings or paired jewelry (ring, pendant, earrings) within a similar total budget.
In summary, selecting a 5-carat marquise diamond involves balancing color, clarity, and cut with the intended jewelry design. Certification, sustainable sourcing, and a well-chosen setting are the pillars of a durable, radiant piece that can be cherished for years to come.
