ROSI™ is our gemologist-built AI that scores each diamond on light performance, structural integrity, and real-world beauty. Every center stone we source for the Lumère is graded 90/100 or higher.
“I worked with the team for three weeks. They guided me through the diamond, the metal, the proportions — every detail. The day it arrived, I knew she’d say yes. She did. Twice.”
“We chose the Lumère because it lets the diamond breathe. The center stone is a 1.8ct ROSI™-scored 96 — it sparkles like crazy. The platinum band is comfortable for everyday wear.”
“I priced this against three other jewelers. RockHer beat all of them on diamond quality at the same price point. The made-to-order timeline was exactly 9 business days. Communication was perfect.”
