Julian Smith
Larsen is fantastic. I went there for an engagement ring and was very impressed with everything. The showroom is beautiful, the team (especially Rachel) are knowledgeable and very helpful throughout the design and crafting process. The timelines were met with no issues and the price was very competitive compared to other reputable jewelers. The ring is stunning - very professionally crafted. My fiancé loves it and I couldn't have asked for anything else with the design. Will definitely be back. Thank you!
