Buying Guide: Key Purchase Considerations

What should you check before buying lab-grown gems?

  • Certification and origin: Look for IGI or equivalent certification that confirms lab-grown origin and provides color, clarity, and cut details.
  • Color and clarity: D–E color with VS1–VS2 clarity typically delivers near-colorless stones with minimal inclusions. Consider your budget and goal for brilliance when selecting color grades.
  • Setting and metal: Two-tone or solid gold settings alter the ring’s look. For pendants, consider chain length and metal tone to match the diamond’s color.
  • Size and shape variety: Lab-grown options come in many shapes and carat sizes. Ensure you can customize to your desired design or need for matching stones.
  • Ethical and environmental impact: Lab-grown stones generally offer lower environmental impact than mined stones; confirm company policies if sustainability matters to you.

How To Choose By Scenario

  • Engagement or anniversary on a budget: Look for classic shapes (emerald, oval) with high color and clarity.
  • Jewelry making: GEMHUB’s small-size diamonds are ideal for micro-settings or pavé work.
  • Gifts and daily wear: Pendants and bracelets with secure settings offer easier maintenance and versatile styling.
  • DIY projects: Round created rubies invite a bold color choice for mixed-metal designs or earring sets.
