Birthstone Chart-Kathleen Lynagh.jpg

A recent trend in engagement ring design is to use your birthstone for the center. Not sure which gems is for your birth month? Check out the chart above, I saved this image from a cherished issue of Town and Country - my favorite magazines for years.

If you are set on your using birthstone please keep in mind, all birthstones are not created equal. You want to wear your ring everyday and last forever?  The key to a long-lasting ring is the hardness of the gem.

If a gemstone scores less than 7.5 on the Moh’s Hardness Scale, think twice about considering it.

The Moh's Hardness Scale measures the durability of a gemstone on a scale of 1-10. The diamond scores 10 out of 10. At the bottom of this scale is the beautiful pearl at 2.5. Easily damaged, pearls are not recommended for an engagement ring if you are considering wearing it daily.

Still like the idea of a birthstone for your engagement ring, check out whether it is resilient enough to withstand everyday wear. The following guide for information only - you should choose the gemstones you want to represent your love and fit your lifestyle. These recommendations are based on my lifestyle - I wear my ring on a daily bases and work with my hands:

January - Birthstone - Garnet 6.5-7.5 on the Moh's Hardness Scale - not really recommended for an engagement ring.

February - Birthstone - Amethyst 7.0 on the Moh's Hardness Scale - again in my opinion not recommended for an engagement ring.

March - Birthstone - Aquamarine 7.5-8.0 on the Moh's Hardness Scale - not the hardiest of gems, but worth considering for an engagement ring.

April - Birthstone - Diamond 10 on the Moh's Hardness Scale - top of the list.

May - Birthstone - Emerald 7.5-8.0 on the Moh's Hardness Scale, but emeralds normally have inclusions - minute cavities trapped inside the gem - which makes them much more fragile than the Moh's Scale suggests. Avoid for an engagement ring.

June - Birthstones - Pearl, Moonstone and Alexandrite At 2.5 on the Moh's Scale, pearls are a definite no-no, as are moonstones, which score 6.0-6-5. Alexandrites score a more robust 8.5, so if you are a June baby, this is only June birthstone we would recommend.

July - Birthstone - Ruby 9.0 on the Moh's Scale - perfectly suited to an engagement ring.

August - Birthstones - Peridot, Sardonyx and Spinel Avoid peridot and sardonyx - a type of onyx - which both score 7.0 on the Moh's scale, while spinel is a more resilient 8.0 and therefore suitable for an engagement ring.

September - Birthstone - Sapphire 9.0 on the Moh's Scale - perfectly suited to an engagement ring.

October - Birthstones - Opal and Tourmaline At 5.5-6.5 on the Moh's Scale, opals are easily scratched, while tourmalines (7.0-7.5) don't quite make the grade either. Avoid both for a birthstone engagement ring.

November - Birthstones - Citrine and Topaz 7.0 and 8.0 respectively on the Moh's Hardness Scale, opt for a topaz birthstone engagement ring if you are born in November.

December - Birthstones - Tanzanite, Blue zircon, Turquoise and Blue topaz December babies are spoilt for choice with their birthstones, but only one - blue topaz, which scores 8.0 on the Moh's Scale - is robust enough to consider for an engagement ring. You can probably get away with blue zircon (7.5), but steer clear of tanzanite (6.5-7.0) and turquoise (5.0-6.0).
