Buying Guide: Oval Cut Loose Diamonds
- What to prioritize: For large stones, prioritize color and clarity (D–E, VVS–VS) to maximize brilliance. For budgeting, consider smaller carats with high color and clarity, or opt for moissanite as a durable alternative.
- Ethical considerations: Lab grown diamonds generally offer lower environmental impact and cost relative to mined diamonds, with comparable physical properties.
- Certificate and grading: Look for IGI or GRA certificates for moissanite, or IGI for lab grown diamonds to verify cut, color, and clarity.
- Shape and setting: Oval cuts elongate the finger and can appear larger than round stones of the same carat. Plan halos, prongs, or bezel settings to protect corners and maximize brilliance.
- Durability and wear: Moissanite has a hardness around 9.25 on the Mohs scale, making it highly resistant to scratches, suitable for daily wear. Diamonds measure 10 on Mohs, providing excellent durability as well.
- Buyer’s checklist: Confirm the stone’s carat weight, color grade, clarity rating, cut quality, and certification. Compare under various lighting to observe fire and brilliance.
FAQ
