As previously mentioned, a birthstone is a gemstone associated with the month you were born. The origin is believed to be from the breastplate of Aaron, the first high priest of the Hebrews. As described in the bible, he wore a breastplate containing twelve gemstones, representing the twelve tribes of Israel. In time, the American jewelry industry agreed upon an official list of birthstones, bringing consistency in the current selection of birthstones by month.
The official list per month is:
|January: Garnet||July: Ruby|
|February: Amethyst||August: Peridot, Spinel or Sardonyx|
|March: Aquamarine or Bloodstone||September: Sapphire|
|April: Diamond||October: Opal or Tourmaline|
|May: Emerald||November: Topaz or Citrine|
|June: Moonstone, Pearl, or Alexandrite||December: Turquoise, Tanzanite or Zircon|
Though the Mohs scale of hardness is a great tool when selecting gemstones for jewelry, some designers will still use softer stones because they’re just too gorgeous not to feature. In practical terms, gems softer than quartz will lose their polish and become dull simply from cleaning. Keep in mind the scale of hardness is a guideline… look how popular pearls (2.5- 4.5) and opals (5.5-6.5) are in today’s market.
At the end of the day, fall in love with a design first, inquire about the stones after. Maybe you’ll find a new favourite: amber, carved gemstones, rose-cut stones, colored diamonds, rough cut diamonds, rutilated quartz are just a few of the stunningly unique options out there. No need to lie about your birthday being in April - just go for what you love.
