A 3.38 carat snowflake cut square octagonal lab-created strontium titanate with 0.11 carats of round white zircon in 18K yellow gold over sterling silver ring - the diamond simulant ring in the unusual snowflake cut applied to a square octagonal stone form. The snowflake faceting pattern creates a distinctive radiating optical display; the square octagonal outer form gives the stone architectural geometry. Diamond simulant produces exceptional fire. Not sizeable.
