Customers often praise Great Heights’ sales team and quick delivery. Many buyers say the finished rings met their expectations and that the lab-grown diamonds looked high quality. Reviewers also like the website and selection for being easy to use and offering plenty of options. One review flags unclear return terms for purchases involving multiple diamonds.
Examples from available reviews (Feb 2026).
Customer service representative Kim was extremely helpful throughout the process.
“She was BEYOND HELPFUL.”
Ring met expectations; arrived weeks after ordering and was perfect.
“it was exactly what I was hoping for.”
Found desired lab diamond within budget; partner was overwhelmed with joy.
“Great Heights ended up having exactly what I wanted within my budget.”
Return policy allegedly misleading; one diamond became final sale unexpectedly.
“if you buy two diamonds, one of them will become a final sale.”
Reviewers describe store staff as friendly and attentive, with guidance tailored to the buyer. Several mention a representative by name and say they received hands-on help while choosing a ring. Multiple comments note staff doing more than typical sales support.
Shoppers say they found lab-grown diamonds that fit both budget and preferences. The range and search tools make it easier to compare options at different price points. Reviews repeatedly mention strong value.
Customers call the website clear and the online ordering process easy. Several note fast shipping, including deliveries that arrived earlier than promised, and confirm U.S. shipping. Many reviewers also point to a simple custom ring-building process.
Buyers say the finished rings looked as expected and drew very positive reactions from partners. Multiple reviewers describe the lab-grown diamonds as convincing in look and craftsmanship. People also report the items arrived in consistently good condition.
One review says the return policy wording was unclear for purchases with two diamonds and ended in a final-sale outcome. This complaint shows up rarely in the reviews. No other communication issues appear with the same level of detail.
Most feedback comes from very satisfied customers who point to service, quality, and ease of use. Many five-star reviews contrast with a single one-star return complaint. That gap stands out, but it remains limited.
