Filter by millimeter size to find your perfect match.

Tips from John

Achieving a professional and secure setting begins with precise measurement. Because oval gemstones have distinct proportions, follow this step-by-step guide to determine the exact millimeter size you need before choosing your pendant setting:

  1. Use a Digital Caliper: Avoid using standard rulers or tape measures. Always use a digital jewelry caliper to measure your loose gemstone. It is the only way to achieve the sub-millimeter accuracy required.
  2. Measure the Length (Longest Dimension): Measure the oval stone along its longest vertical axis, running from tip to tip. Record this measurement in millimeters.
  3. Measure the Width (Widest Dimension): Measure the stone across its widest horizontal axis, running perpendicular to the length. Record this in millimeters.
  4. Compare with Calibrated Sizes: Match your length x width measurements to our standard size options (e.g., if your stone measures 7.9mm by 5.9mm, it will perfectly fit our standard 8x6 mm oval setting).
  5. Tolerance Rule: Our precision oval settings are designed to accommodate minor variances. For optimal results, your gemstone should be within +/- 0.1mm of the target setting size. For example, an 8x6mm setting can comfortably accommodate stones measuring between 7.9mm to 8.1mm in length, and 5.9mm to 6.1mm in width.

The oval cut is one of the most elegant and visually impactful gemstone shapes. Choosing a dedicated, shape-specific oval setting offers several distinct advantages for fine jewelry designs:

  • Enhanced Visual Presence: Due to their elongated shape, oval gemstones often look larger face-up than round gemstones of the equivalent carat weight. A dedicated oval setting capitalizes on this visual advantage, creating a striking focal point.
  • Elongating Aesthetic: When worn as a pendant, the vertical orientation of an oval setting creates an elegant, elongating effect on the neckline, making it a highly desirable choice for custom fine jewelry.
  • Symmetry and Balance: Our oval settings are engineered to highlight the brilliant symmetry of your stone. Precise basket alignments and perfectly spaced prongs ensure the stone is centered, maximizing light return and fire.
  • Secure Prong Geometry: Our 4-prong and 6-prong oval mountings are positioned strategically at the corners and sides of the oval curve. This specialized geometry protects the most vulnerable points of the stone while allowing maximum light entry to enhance the gemstone's natural brilliance.

FAQs

Unlike round gemstones, oval-cut stones are highly sensitive to length-to-width ratios, which typically range from 1.33 to 1.50. A precision-fit setting is critical because even a minor variance of 0.1mm can prevent the stone from resting flat in the basket, causing it to sit crooked or rock back and forth. Precision sizing ensures that the prongs or bezel align perfectly with the stone's curves, distributing setting pressure evenly and securing your gemstone safely.
