Buying Guide
What to consider when choosing a marquise diamond pendant:
- Certification: IGI or IGI-certified claims support value and quality, especially for lab-grown stones. Look for carat weight, color, and clarity specifics.
- Metal choice: 14K white gold provides cool tones that enhance brilliance; yellow gold offers warmth and a classic look; sterling silver is a budget-friendly option with different durability considerations.
- Diamond cut and shape impact: The marquise cut elongates the look of the neck and can visually enlarge the diamond due to its slender silhouette. Ensure a secure prong setting to maximize light exposure.
- Chain length and adjustability: Common lengths are 18 inches; consider an adjustable chain if layering or varying necklines is expected.
- Clarity and color balance: VS1-VS2 with E-F-G color typically delivers strong visual sparkle without obvious inclusions in most lighting conditions.
- Budget and use-case: For daily wear, prioritize durability and hypoallergenic metals; for gifting, consider certifications, packaging, and presentation.
