SQ refers to square cut synthetic quartz, an elegant cut with 90-degree corners. Alternating triangular and four-sided facets are precisely arranged in symmetrical rows. This orderly faceting creates outstanding optical brilliance. The broad, flat facets act like mirrors to disperse light. Square cuts look magnificent set in simple solitaire mounts. The straight lines and geometric corners create a clean, contemporary look. SQ synthetics offer exceptional fire and sparkle. They come in classic transparent white or bold shades like cobalt and cherry. Durable yet dazzling, SQ quartz suits Art Deco styles as well as modern fashions. Their flawless clarity is beautifully displayed by the square’s large, open facets. For understated luxury, SQ synthetics are an ideal choice.
