Buying Guide
What should I consider when choosing a marquise 1 ct diamond?
Evaluate color, clarity, cut, and carat weight in balance. Near-colorless colors (F-G, D-E) and high clarity (VVS-VS) maximize brilliance in marquise shapes, but cost rises with higher grades. Lab-grown diamonds offer ethical sourcing and savings without sacrificing visual quality.
Lab-grown vs mined: which is better for a marquise shape?
Lab-grown diamonds provide identical physical and optical properties to mined stones and usually cost less. They also offer a lower environmental impact. For marquise shapes, consistency in cut precision is essential to maximize the stone’s elongated silhouette and flame-like sparkle.
Certification and authenticity: how to compare?
Look for IGI or GIA (or equivalent) certifications. Certifications confirm color, clarity, cut grade, and carat weight. They provide confidence in grading and help with future resale or appraisals.
Practical setting tips: choosing the right setting for a marquise
Marquise stones look striking in elongated settings. Ensure the setting accommodates the stone’s dimensions and protects pointed ends. Be mindful of the stone’s girdle width and length-to-width ratio to preserve brilliance in the final piece.
Color and brilliance: what’s the impact on appearance?
Color grades from D-E to F-G offer near-colorless tones that maximize sparkle. In marquise shapes, higher color grades can enhance the stone’s perceived brightness, but the setting color and metal influence the final look.
Care and maintenance: how to keep brilliance?
Clean gently with warm soapy water and a soft brush. Avoid harsh chemicals. Regularly inspect prongs or settings to prevent loss, especially for marquise stones with extended points that can be vulnerable to damage.
