Summer Jewellery Trends – Yellow Diamonds, Cognacs and Sapphires

If you’re a summer-loving sister, check out these beautiful coloured gemstones and diamonds that would be perfect to ring in summer.

Yellow Diamonds

Yellow diamonds were rarely seen until their discovery in South Africa in the late 1860s. Yellow diamonds are less common than the colourless diamonds, but are far more common than blue, pink, and red diamonds.

Yellow diamonds come in a variety of shades and are graded in order from; fancy light, fancy, fancy intense and fancy vivid being the most opaque in colour. If you’re in the market for an engagement ring and don’t want to go for a typical white diamond, try yellow diamonds. They’re also a fantastic investment piece.


Cognacs, also know as brown diamonds were typically considered good only for industrial use until the 1980s, when abundant quantities of them began to appear in the production of the Argyle mines. In Australia, we gave them names like “cognac” and “champagne” and they are very popular alternatives to diamonds for engagement rings and dress rings.

Yellow Sapphires

Happy, bright, and beautiful, yellow sapphires sparkle from every angle and come in a variety of shades. Sapphires have an extremely high refractive rate, meaning they’re extremely sparkly. Perfect for your engagement or dress ring.

  • Mineral: Corundum
  • Chemistry: Al2O3

  • Birefringence: 0.008 to 0.010

These stones channel the cheeriness of a sunny day; it’s impossible not to smile when you see a yellow sapphire.

August Birthstone: Spinel Gemstone

August Birthstone: Spinel~

Spinel is a good candidate for the title of “History’s Most Underappreciated Gem.” Some ancient mines that supplied gems for royal courts from Rome to China produced spinel, but it was usually confused with better-known stones like ruby and sapphire.

At Artisans Gems and Jewels, we love working with Spinels as they come in a variety of colors, in particular red and pink. Mauve- or lilac-colored spinels are also attractive, and some blue spinel colors can be intense.

Spinel Facts
  • Mineral:   spinel
  • Chemistry: MgAl2O4
  • Color: red, orange, pink, purple, blue, black
  • Refractive index: 1.718
  • Birefringence: none
  • Specific gravity: 3.60
  • Mohs Hardness: 8

Here are some beautiful Spinel combinations we have available to incorporate into your jewellery designs.

Gemstone Feature: Alexandrite

Gemstone Feature: Alexandrite~

Alexandrite was discovered in 1830 in Russia’s Ural Mountains and is one of the rarest gemstones to source, particularly in large sizes. Because of its scarcity, alexandrite is a relatively expensive member of the chrysoberyl family. It shares its status as a June birthstone with cultured pearl and moonstone.

  • Mineral: Chrysoberyl
  • Chemistry: BeAl2O4
  • Color: Bluish green in daylight, purplish red in incandescent light
  • Refractive Index: 1.746 to 1.755
  • Birefringence: 0.008 to 0.010
  • Specific Gravity: 3.73
  • Mohs Hardness: 8.5

Alexandrite, with its chameleon-like qualities, is a rare variety of the mineral chrysoberyl.

Its color can be a lovely green in daylight or fluorescent light, changing to brownish or purplish red in the incandescent light from a lamp or candle flame. This is a result of the complex way the mineral absorbs light.

Alexandrite is also a strongly pleochroic gem, which means it can show different colors when viewed from different directions.
