A little extra care can keep your rings looking and feeling their best.

Avoid harsh chemicals such as bleach remove jewelry when showering, deep
cleaning, going in the hot tub, pool etc. to avoid buildup.

We have a lot of hardened metals in our world today that can scratch and
ding precious metals like silver & gold. Avoid things with metal
handles like garden tools. The serrated metal of gym equipment and free
weights are the worst it is best to leave your jewelry at home when
going to the gym doing yard work etc.

Gemstones vary in their hardness and durability. Softer gems require more care.

Example of softer gems - pearls, moonstone, quartz.

Example of harder gems - sapphire and diamonds.

You can research the Mohs scale for more information.

For at home cleanings I recommend using a soft tooth brush and some warm
soapy water. I recommend a mild and natural soap like a Dr. Bronners or
a Mrs. Meyers. If your ring has stones you want to be sure to clean
behind them as well to help them stay extra sparkly.

If you have a high shine silver ring that you want to stay as shiny as
possible store it in an air tight container when not wearing it to avoid
oxidization.

I have always been drawn to symbolism and the moon. I love the perfect balance of the triple moon symbol and the meaning behind it which is quite deep. The triple moon symbol has the full moon in the center and a waxing and waning crescent on either side and is symbol of the divine feminine. It symbolizes the past present and future as well as the 3 phases of a womans life - *** The Maiden the Mother and the Crone ***
The waxing moon represents the Maiden, growing with potential and new beginnings, youth, innocence and new opportunities.
The full moon represent the Mother and the mastery of giving and receiving love including self love, Fertility, nurturing and realized potential.
The waning moon represents the Crone, wisdom, contentment, self mastery and awareness and fulfillment.

The center stone represents the full moon and is a 6mm (shown in rose gold) or 6.5mm (shown in yellow gold) Chatham Alexandrite that weighs approximately 1.10 carats, the larger side stones are also Chatham color change Alexandrites with a combined weight of approx. .25 carats. The engagement ring is set with 8 additional black or white diamonds, they have a combined carat weight of approximately .12 carats, the white diamonds are VS clarity. The black diamonds have been heat treated to make their color solid.

The bottom wedding band is chevron shaped and set with an additional 15 diamonds, they have a combined approximate weight of .19 carats and can be set with black or white diamonds.
The top wedding band is our Sunray ring that is set with an additional approx. .07 carats of VS white or black diamonds.

**PLEASE leave me a note in the notes to seller box at checkout with your preference of side diamonds, your rings can be set with black or white diamonds)

The engagement ring on its own is 14mm's wide across the widest point at the top and the band is about 2mm's wide.
When stacked the 3 ring set is approximately 22mm's wide across the top and each band is about 2mm's wide.
