New York—After a year filled with ups and downs, Eriness founder and designer Erin Sachse has released her “One of One” collection.
Inspired by motherhood, birth, growth, loss, new beginnings, and ending chapters, Sachse created 10 one-of-a-kind designs that reflect this period of her life.
Each day of the past year had been uncharted territory and the transformation that came from it impacted her design, the brand said.
“I designed the One of One collection while I was pregnant with my son Julius, a time filled with so much joy and anticipation about bringing life into this world. It was also a period of profound loss and reflection, as I prepared to become a mom without my own mom by my side,” said Sachse.
“On top of it all, my family home burned down [in the LA wildfires] during my third trimester. A lot of chaos and a lot of feelings! The designs in this collection reflect this beautiful, emotional period in my life.”

At the center of this pendant necklace is a vivid 3.31-carat peridot framed by brilliant-cut blue sapphire pavé in 14-karat yellow gold ($5,650)
The “Spiral” ring with a 4.96-carat blue tourmaline cabochon and tsavorite pavé in 14-karat yellow gold ($6,295)

A signet ring featuring a 2-carat emerald-cut aquamarine set in 14-karat yellow gold ($3,650)
Each of the 10 pieces are one-of-a-kind with colored gemstones in 14-karat yellow gold, including sapphire, aquamarine, tourmaline, tsavorite, peridot, and orange garnet, with diamonds as accents.
Rare and unusual gemstones layered with character were sourced for the collection, so no piece can truly be replicated in its exact form, said the brand.
There are four rings, four pendants, a pair of huggies, and a pair of earrings, all created to be irreplaceable and hold their own story.
The One of One collection launched on Oct. 10.
Its one-of-a-kind pieces retail from $1,090 to $8,295 and are available on the Eriness website.
