Study Notes

Diamond Education

  • Carat:
    • 1 carat equals 200 milligrams
    • Different diamond shapes can appear different sizes for the same carat weight
    • Princess cut diamonds have most weight in the center, which makes them appear smaller
    • Sapphire is heavier than a diamond.
    • Size is an important factor for lifestyle considerations, especially for those with more active lifestyles.
    • Average diamond size desired is now 2 carats, down from the 20,000+ dollar price range to the 6,000+ dollar price range.

Diamond Color

  • A color grading system was created in the early 1900s to standardize grading, using the letters D through Z to identify colors.
  • D-F are considered colorless.
  • G-J are considered near colorless.
  • K-M are considered faint.
  • N-R are considered very light.
  • S-Z are considered light colored.
  • Colorless through light colors are what are typically worked with most.

Diamond Clarity

  • Clarity refers to internal characteristics like inclusions, which can include Carbon deposits, feathers (looking like cracks), and crystal deposits.
  • Flawless (no visible inclusions, no blemishes)
  • Internally flawless (no visible inclusions, but may have blemishes)
  • Very very Slightly Included: VVS1, VS2 (inclusions difficult for trained graders to see)
  • Very Slightly Included: VS1, VS2 (inclusions require some magnification to see)
  • Slightly Included (SI): SI1, SI2 (inclusions will be noticeable)

Diamond Cut

  • Cut refers to the facets and the way light reflects off the diamond.
  • Cut quality affects sparkle (fire and scintillation).
  • Ideal, deep, and shallow cut diamonds are possible results.
  • Shape and how light reflects affect different looks and symmetry.
  • Excellent and Very Good are ideal cuts, while Poor and Fair may not reflect light correctly.

### Diamond Fluorescence

  • Fluorescence is a natural effect of some diamonds.
  • When exposed to black light it can make some diamonds appear cloudy in daylight.
  • This can slightly detract from the price of the diamond.

Diamond Certificates

  • Certificates are created by labs to ensure authenticity in grading.
  • The grading is done by an independent third party lab so there's no conflict of interest.
  • GIA is the most common body involved.
  • Canadian origin diamond labels cost extra to include.
  • Smaller stones are often sold in groups

Gemstone Video #2

  • Sapphires, emeralds, and rubies aren't typically given certificates because those types of gems are already determined by specific origins and qualities.
  • Gemstones can be traced back to where and how they were mined.
  • Gemstones are typically described using terms that are clear and understandable (rather than overly technical).
  • "Inclusions", visible imperfections, are normal in non-diamond gemstones.
