The play-of-color effect is very beautiful. This grape motif is in very beautiful condition. It has even more red than in the photos. Thank you for the likes. It also uses solid K18 gold. Due to the rising price of gold, I apologize to those who are considering it, but if the price continues to rise, I will have to raise the price a little, so if possible, please purchase it sooner...^_^ This is a brooch and pendant in one, featuring a grape cluster design using opal stones. - Design: Grape cluster shape - Material: K18 (hallmark present) Diamond Opal All hallmarks are present. - Color: Multicolor (iridescent) - more red than in the photos - Size: Approximately 3.5cm x 2.5cm at the largest points Diamond: 0.06 (hallmark present) Opal: 3.5ct (hallmark present) Weight: Approximately 7 grams of K18 There are no chips or damage to the stones.
