Royal Sapphire Blue River Rocks – 4.5 lb Decorative Stones for Aquariums, Gardens & Terrariums

Overview

Royal Sapphire Blue River Rocks offer a versatile decorating solution that blends natural beauty with practical, easy-care use. Each pebble is smooth and rounded, designed to be gentle to touch and to sit securely in any display. The blue hue is deep and varied, catching light to create subtle gradients across a surface. The set weighs about 4.5 lbs and contains roughly 60 stones, with sizes spanning about 2 cm to 3.5 cm for flexible arrangement options.

As an alternative to mulch, these decorative river pebbles can be used indoors or outdoors. They support soil moisture retention while helping drainage in beds or planters. Their durable, weather-resistant finish holds color over seasons, and the rounded shapes are safe for barefoot spaces, gatherings, and everyday display ideas.
